fulcrum-js

A JavaScript and TypeScript library for the Fulcrum API.

Installation

npm install --save @fulcrumapp/fulcrum-js

Quick Start

Using the Fulcrum Client

The easiest way to get started is with the FulcrumClient:

import { FulcrumClient, FulcrumRegion } from '@fulcrumapp/fulcrum-js';

const client = new FulcrumClient({
  apiKey: 'your-api-token',
  region: FulcrumRegion.US,  // Required: US, AU, CA, EU, or custom URL
  userAgent: 'MyApp/1.0.0'   // Optional but recommended
});

// Get all forms
const formsResponse = await client.forms.getAll();
console.log(formsResponse.data);

// Get records for a specific form
const recordsResponse = await client.records.getAll({ formId: 'form-id-here' });
console.log(recordsResponse.data);

Data Residency / Regional Endpoints

Fulcrum supports multiple data residency regions. You must specify a region when creating the client:

import { FulcrumClient, FulcrumRegion } from '@fulcrumapp/fulcrum-js';

// United States
const usClient = new FulcrumClient({
  apiKey: 'your-api-token',
  region: FulcrumRegion.US  // https://api.fulcrumapp.com/api/v2
});

// Australia
const auClient = new FulcrumClient({
  apiKey: 'your-api-token',
  region: FulcrumRegion.AU  // https://api.fulcrumapp-au.com/api/v2
});

// Canada
const caClient = new FulcrumClient({
  apiKey: 'your-api-token',
  region: FulcrumRegion.CA  // https://api.fulcrumapp-ca.com/api/v2
});

// European Union
const euClient = new FulcrumClient({
  apiKey: 'your-api-token',
  region: FulcrumRegion.EU  // https://api.fulcrumapp-eu.com/api/v2
});

// Custom endpoint (for internal clients or new regions)
const customClient = new FulcrumClient({
  apiKey: 'your-api-token',
  region: 'https://custom.fulcrum.com/api/v2'
});

TypeScript Support

import { FulcrumClient, FulcrumRegion } from '@fulcrumapp/fulcrum-js';
import type { FormsResponse } from '@fulcrumapp/fulcrum-js';

const client = new FulcrumClient({
  apiKey: 'your-api-token',
  region: FulcrumRegion.US,
  userAgent: 'MyApp/1.0.0'
});

// Get all forms with full type safety
const response = await client.forms.getAll();
const forms: FormsResponse = response.data;
forms.forms?.forEach((form) => {
  console.log(form.name);
});

CommonJS (Node.js)

If you need CommonJS for compatibility with older Node.js projects:

const { FulcrumClient, FulcrumRegion } = require('@fulcrumapp/fulcrum-js');

const client = new FulcrumClient({
  apiKey: 'your-api-token',
  region: FulcrumRegion.US
});

// Get all forms
client.forms.getAll().then(response => {
  console.log(response.data);
});

Version History

Version 3.0 (Latest)

Direct axios responses instead of wrapped Page objects
All methods return Promise<AxiosResponse<T>> for consistent response handling
Full TypeScript support with comprehensive type definitions

New Features:

🎯 271+ API methods covering the complete Fulcrum API
🔒 Full TypeScript support with 106 TypeScript interfaces
📦 Auto-generated from OpenAPI spec - always up-to-date with API changes
⚡ Modern axios-based HTTP client - better error handling and OTEL support
🧩 Comprehensive type safety - catch errors at compile time
📚 Enhanced API coverage including Report Templates, Workflows, Batch Operations, Groups, and more
🎁 Dual module support - ES Modules (recommended) and CommonJS for compatibility
📊 Built-in OpenTelemetry instrumentation - automatic tracing for all API calls

See the Upgrading section for migration details.

Version 2.x

Version 1 of this library used callbacks for API responses. Version 2 uses Promises. Promises offer some advantages over the callback pattern used previously. You can read more about them in the Promises section.

Usage

The v3 API provides a clean, resource-based interface through the FulcrumClient:

import { FulcrumClient, FulcrumRegion } from '@fulcrumapp/fulcrum-js';

const client = new FulcrumClient({
  apiKey: 'your-api-token',
  region: FulcrumRegion.US,  // Required: US, AU, CA, EU, or custom URL
  userAgent: 'MyApp/1.0.0'   // Optional but recommended
});

All methods are organized by resource (records, forms, projects, etc.) and return axios responses with full TypeScript support.

Using the Wrapper Client

The wrapper client provides a simpler, more intuitive API:

import { FulcrumClient, FulcrumRegion } from '@fulcrumapp/fulcrum-js';

const client = new FulcrumClient({
  apiKey: 'your-api-token',
  region: FulcrumRegion.US,  // Required
  userAgent: 'MyApp/1.0.0'   // Optional
});

Working with Records

// Get all records for a form
const response = await client.records.getAll({
  formId: 'form-id-here',
  perPage: 1000,
  page: 1
});
console.log(`Found ${response.data.records?.length} records`);

// Get a single record
const recordResponse = await client.records.getById('record-id');
const record = recordResponse.data.record;

// Create a record (no content-type headers needed!)
const createResponse = await client.records.create({
  record: {
    form_id: 'form-id-here',
    status: 'submitted',
    latitude: 40.7128,
    longitude: -74.0060,
    form_values: {
      'field-key': 'value'
    }
  }
});

// Update a record
await client.records.update('record-id', {
  record: {
    form_values: {
      'field-key': 'new value'
    }
  }
});

// Delete a record
await client.records.delete('record-id');

// Get record history
const historyResponse = await client.records.getHistory('record-id');

Working with Forms

// Get all forms
const formsResponse = await client.forms.getAll();
const forms = formsResponse.data.forms;

// Get all forms with pagination
const paginatedResponse = await client.forms.getAll({
  page: 1,
  perPage: 100
});

// Create a form
const createFormResponse = await client.forms.create({
  form: {
    name: 'My New Form',
    description: 'Form description'
  }
});

// Update a form
await client.forms.update('form-id', {
  form: {
    name: 'Updated Form Name'
  }
});

// Delete a form
await client.forms.delete('form-id');

Working with Projects

// Get all projects
const projectsResponse = await client.projects.getAll();

// Create a project
await client.projects.create({
  project: {
    name: 'My Project',
    description: 'Project description'
  }
});

// Update a project
await client.projects.update('project-id', {
  project: {
    name: 'Updated Project'
  }
});

// Delete a project
await client.projects.delete('project-id');

Working with Webhooks

// Get all webhooks
const webhooksResponse = await client.webhooks.getAll();

// Create a webhook
await client.webhooks.create({
  webhook: {
    name: 'My Webhook',
    url: 'https://example.com/webhook'
  }
});

// Update a webhook
await client.webhooks.update('webhook-id', {
  webhook: {
    name: 'Updated Webhook'
  }
});

// Delete a webhook
await client.webhooks.delete('webhook-id');

Query API

// Execute a query (JSON format is default)
const queryResponse = await client.query.get({
  q: 'SELECT * FROM "My Form" WHERE status = \'submitted\' LIMIT 100'
});

const rows = queryResponse.data.rows;

Accessing the Full API

For API methods not yet wrapped, access the full underlying API client:

// Access any of the 271+ API methods directly
const response = await client.client.changesetsGetAll();
const response2 = await client.client.photosGetAllMetadata({ formId: 'form-id' });

This gives you access to all Fulcrum API endpoints while still benefiting from the configured client.

OpenTelemetry Instrumentation

The Fulcrum client includes built-in OpenTelemetry instrumentation that automatically creates spans for all API operations. This provides automatic distributed tracing without any additional configuration.

How It Works

Every API call is wrapped in a span with a descriptive name (e.g., Records.getAll, Forms.create) that will appear in your traces alongside the automatic HTTP spans created by axios instrumentation. This gives you both high-level operation context and low-level HTTP details.

Span Naming Pattern: <Resource>.<operation>

Examples:

Records.getAll - Fetching all records
Records.getById - Fetching a single record
Forms.create - Creating a new form
Query.post - Executing a SQL query

Span Attributes

Spans include relevant Fulcrum-specific attributes:

fulcrum.form_id - Form ID for record operations
fulcrum.record_id - Record ID for single record operations
fulcrum.project_id - Project ID for project operations
fulcrum.skip_workflows - Whether workflows were skipped
fulcrum.skip_webhooks - Whether webhooks were skipped
fulcrum.query.sql - SQL query being executed
fulcrum.query.format - Query response format (json/csv/geojson)

Example: Setting Up Tracing

import { NodeSDK } from '@opentelemetry/sdk-node';
import { getNodeAutoInstrumentations } from '@opentelemetry/auto-instrumentations-node';
import { ConsoleSpanExporter } from '@opentelemetry/sdk-trace-node';
import { FulcrumClient, FulcrumRegion } from '@fulcrumapp/fulcrum-js';

// Initialize OpenTelemetry
const sdk = new NodeSDK({
  traceExporter: new ConsoleSpanExporter(),
  instrumentations: [getNodeAutoInstrumentations()],
});

sdk.start();

// Create Fulcrum client - tracing is automatic
const client = new FulcrumClient({
  apiKey: 'your-api-key',
  region: FulcrumRegion.US,
});

// All API calls are automatically traced
const records = await client.records.getAll({ formId: 'abc123' });

// Your trace will show:
// └─ Records.getAll (fulcrum.form_id: abc123)
//    └─ HTTP GET https://api.fulcrumapp.com/api/v2/records

Trace Hierarchy

When you make an API call, you'll see a trace hierarchy like this:

Your Application Span
└─ Records.create (fulcrum.form_id: abc123, fulcrum.skip_workflows: false)
   └─ HTTP POST https://api.fulcrumapp.com/api/v2/records
      └─ DNS lookup
      └─ TCP connection
      └─ TLS handshake
      └─ HTTP request/response

The Fulcrum span (Records.create) provides business context, while the nested HTTP span provides technical details about the network request.

Error Tracking

Errors are automatically recorded in spans with full exception details:

try {
  await client.records.getById('invalid-id');
} catch (error) {
  // Span will be marked as error with exception details
  // Error status and message automatically recorded
}

Custom Instrumentation

The client uses the standard OpenTelemetry API, so you can add your own custom spans:

import { trace } from '@opentelemetry/api';

const tracer = trace.getTracer('my-app');

await tracer.startActiveSpan('processRecords', async (span) => {
  span.setAttribute('record.count', 100);

  // Fulcrum API calls will be nested under this span
  const records = await client.records.getAll({ formId: 'abc123' });

  // Your processing logic
  for (const record of records.data.records || []) {
    // Process each record
  }

  span.end();
});

This creates a trace hierarchy like:

processRecords (record.count: 100)
└─ Records.getAll (fulcrum.form_id: abc123)
   └─ HTTP GET https://api.fulcrumapp.com/api/v2/records

Working with Forms (Low-Level API)

const form = formResponse.data.form;
console.log(form.elements);  // Access form schema

// Create a form
await api.formsCreate('application/json', 'application/json', {
  form: {
    name: 'My New Form',
    description: 'Created via API',
    elements: [
      {
        type: 'TextField',
        key: 'name',
        label: 'Name',
        required: true
      }
    ]
  }
});

// Update a form
await api.formsUpdate('form-id', 'application/json', 'application/json', {
  form: {
    name: 'Updated Form Name'
  }

        version: '1.0.0'
      }
    }
  }
);

const changesetId = changesetResponse.data.changeset.id;

// Perform operations with the changeset
await api.recordsCreate(
  'application/json',
  'application/json',
  false,
  false,
  {
    record: {
      form_id: 'form-id',
      changeset_id: changesetId,
      form_values: {}
    }
  }
);

// Close the changeset
await api.changesetsClose(changesetId);

TypeScript Usage Tips

Using Types for Better IDE Support

import {
  DefaultApi,
  Configuration,
  // Response types
  RecordsResponse,
  FormsResponse,
  ProjectsResponse,
  // Model types
  Record as FulcrumRecord,
  Form,
  Project,
  // Request types
  RecordsCreateRequest,
  FormsCreateRequest
} from '@fulcrumapp/fulcrum-js';

// Type-safe record creation
const createRecordRequest: RecordsCreateRequest = {
  record: {
    form_id: 'form-id',
    status: 'submitted',
    latitude: 40.7128,
    longitude: -74.0060,
    form_values: {
      'name': 'John Doe'
    }
  }
};

// Using the client
const response = await client.records.create(createRecordRequest);

// TypeScript knows the response type
const record: FulcrumRecord = response.data.record;

Type-Safe Form Values

// Define your form structure
interface MyFormValues {
  name: string;
  age: number;
  email: string;
}

// Create type-safe record
const createRequest: RecordsCreateRequest = {
  record: {
    form_id: 'my-form-id',
    form_values: {
      'name': 'John',
      'age': 30,
      'email': '[email protected]'
    } as MyFormValues
  }
};

Handling Errors

import { AxiosError } from 'axios';

try {
  const response = await api.recordsGetSingle('invalid-id');
} catch (error) {
  if (error instanceof AxiosError) {
    console.error('API Error:', error.response?.status);
    console.error('Message:', error.response?.data);
  } else {
    console.error('Unexpected error:', error);
  }
}

Upgrading from v2 to v3

Version 3 is a major rewrite with breaking changes. The new API provides complete type safety and comprehensive API coverage.

What Changed

1. Import Paths and Module System

v3 uses ES Modules by default (with CommonJS support for compatibility).

v2.x:

// CommonJS only
const { Client } = require('@fulcrumapp/fulcrum-js');
const client = new Client('token');

v3.0:

// ES Modules (recommended) - Use the wrapper client!
import { FulcrumClient, FulcrumRegion } from '@fulcrumapp/fulcrum-js';

const client = new FulcrumClient({
  apiKey: 'token',
  region: FulcrumRegion.US
});

// Or CommonJS for legacy compatibility
const { FulcrumClient, FulcrumRegion } = require('@fulcrumapp/fulcrum-js');

2. Method Names and Structure

The API structure changed from resource-oriented to flat method names.

v2.x:

// Resource-based API
await client.records.all({ form_id: 'abc' });
await client.records.find('record-id');
await client.records.create({ form_id: 'abc', ... });
await client.records.update('id', { ... });
await client.records.delete('id');
await client.forms.all();
await client.forms.find('form-id');

v3.0:

// Use the wrapper client for a cleaner API
await client.records.getAll({ formId: 'abc' });
await client.records.getById('record-id');
await client.records.create({ record: { form_id: 'abc', ... } });
await client.records.update('id', { record: { ... } });
await client.records.delete('id');
await client.forms.getAll();
await client.forms.getById('form-id');

3. Response Structure

v2.x returned custom Page objects:

const page = await client.records.all({ form_id: 'abc' });
console.log(page.objects);        // Array of records
console.log(page.currentPage);    // Current page number
console.log(page.totalPages);     // Total pages
console.log(page.totalCount);     // Total count

v3.0 returns standard axios responses:

const response = await api.recordsGetAll(false, undefined, 'abc');
console.log(response.data.records);     // Array of records
console.log(response.status);           // HTTP status code
console.log(response.headers);          // Response headers
console.log(response.data);             // Full response body

4. Error Handling

v2.x:

try {
  const record = await client.records.find('id');
} catch (error) {
  console.error(error.message);
}

v3.0 uses axios error structure:

import { AxiosError } from 'axios';

try {
  const response = await api.recordsGetSingle('id');
} catch (error) {
  if (error instanceof AxiosError) {
    console.error('Status:', error.response?.status);
    console.error('Data:', error.response?.data);
  }
}

5. Query API

v2.x:

const result = await client.query('SELECT * FROM "Form"');
const geojson = await client.query('SELECT * FROM "Form"', 'geojson');

v3.0:

const jsonResponse = await api.queryPost('application/json', 'application/json', {
  q: 'SELECT * FROM "Form"'
});

const geoResponse = await api.queryPost('application/geo+json', 'application/json', {
  q: 'SELECT * FROM "Form"'
});

6. Media Handling

v2.x:

// Upload photo
const stream = fs.createReadStream('photo.jpg');
await client.photos.create(stream, { accessKey: 'key' });

// Download photo
const photoStream = await client.photos.media('photo-id', 'large');
photoStream.pipe(fs.createWriteStream('photo.jpg'));

v3.0:

// Upload photo
await api.photosUpload('application/json', 'image/jpeg');

// Download photo
const response = await api.photosLargeFile('photo-id');
// response.data contains the file blob

7. Changesets

v2.x:

const changeset = await client.changesets.create({
  form_id: 'form-id',
  metadata: { app: 'my-app' }
});

await client.records.delete('record-id', changeset.id);
await client.changesets.close(changeset.id);

v3.0:

const response = await api.changesetsCreate('application/json', 'application/json', {
  changeset: {
    form_id: 'form-id',
    metadata: { app: 'my-app' }
  }
});

const changesetId = response.data.changeset.id;

await api.recordsDelete('record-id');  // Changeset handled differently
await api.changesetsClose(changesetId);

Migration Strategy

Recommended: Use the Wrapper Client

The v3 wrapper client (FulcrumClient) provides a clean, resource-oriented API similar to v2:

Install v3:

npm install @fulcrumapp/fulcrum-js@latest

Update your imports:

// Old v2 code
import { Client } from 'fulcrum-app';

// New v3 code
import { FulcrumClient, FulcrumRegion } from '@fulcrumapp/fulcrum-js';

Update client initialization:

// Old v2
const client = new Client('api-token');

// New v3
const client = new FulcrumClient({
  apiKey: 'api-token',
  region: FulcrumRegion.US  // Must specify region
});

Method names are slightly different but similar:
- .all() → .getAll()
- .find() → .getById()
- Parameters are now typed objects instead of positional

Advanced: Direct Generated API Access

For advanced use cases, you can access the full generated API client directly through client.client:

import { FulcrumClient, FulcrumRegion } from '@fulcrumapp/fulcrum-js';

const client = new FulcrumClient({
  apiKey: 'token',
  region: FulcrumRegion.US
});

// Access any of the 271+ API methods directly
const response = await client.client.changesetsGetAll();

V2 Usage (Legacy)

Note: The following documentation is for v2.x. If you're using v3.0, see the Usage section above.

There are three main exports from this module: Client, getUser, and createAuthorization.

Client

API calls are made using a client. Let's assume you already have an API token and you want to make some calls to the API. If you need an API token, see the getUser and createAuthorization functions.

import { Client } from '@fulcrumapp/fulcrum-js';
// or
// const fulcrum = require('@fulcrumapp/fulcrum-js');
// const Client = fulcrum.Client;

const client = new Client('your-api-token');

client.forms.all({schema: false})
  .then((page) => {
    console.log(`I got you ${page.objects.length} forms.`);
  })
  .catch((error) => {
    console.log('Error getting your forms.', error.message);
  });

Various methods are available for each of the resources. Check the chart below for details.

Client Resources and Methods

Resource	Methods
Forms	find, all, create, update, delete, history
Records	find, all, create, update, delete, history
Projects	find, all, create, update, delete
Changesets	find, all, create, update, close
Choice Lists	find, all, create, update, delete

Memberships	all, create, change
Roles	all
Child Records	all
Layers	find, all, create, update, delete
Audit Logs	find, all
Authorizations	find, all, create, update, delete, regenerate

find

Finds a single resource. The single parameter is a resource id.

This method returns a Promise containing the resource.

client.forms.find('abc-123')
  .then((form) => {
    console.log('success', form);
  })
  .catch((error) => {
    // There was a problem with the request. Is the API token correct?
    console.log(error.message);
  });

Check the Fulcrum API Docs for an example of returned objects.

all

Search for resources. The single parameter is an options object. The options object will be converted to query string parameters and properly url encoded. The options will vary depending on the resource, but the pagination options, page and per_page, are always accepted.

This method returns a Promise containing a page. The page object has 5 properties.

property	description
`objects`	An array of the resources requested
`currentPage`	The current page
`perPage`	The number of resources returned per page
`totalPages`	The total number of pages required to return all resources
`totalCount`	The total count of all resources with respect to current query parameters

const options = {
  form_id: '043d36a5-d144-4bca-b6ce-be210476e913',
  page: 1,
  per_page: 2
}

client.records.all(options)
  .then((page) => {
    console.log(
      `Got page ${page.currentPage} of ${page.totalPages} containing ${page.objects.length} of ${page.totalCount} total resources.`
    );
    // Got page 1 of 5 containing 2 of 10 total resources.
  })
  .catch((error) => {
    console.log(error.message);
  });

create

Create a resource. The single parameter is an object. The object should represent the resource you are creating. Check the Fulcrum API Docs for examples of resource objects.

This method returns a Promise containing the created resource.

const obj = {
  name: 'My Awesome Webhook',
  url: 'http://foo.com/fulcrum_webhook',
  active: true
};

client.webhooks.create(obj)
  .then((webhook) => {
    console.log('success', webhook);
  })
  .catch((error) => {
    console.log(error.message);
  });

update

Update an object. Parameters are a resource id and an object. The id is the unique id for the resource to be updated. The object should represent the resource you are updating.

This method returns a promise containing the updated resource.

const obj = {
  name: 'My Awesome Webhook',
  url: 'http://foo.com/fulcrum_webhook',
  active: false,
  id: '139c8c99-d4e4-4bf0-a0c5-ed6b6e2e5605'
};

client.webhooks.update(obj.id, obj)
  .then((webhook) => {
    console.log('success', webhook);
  })
  .catch((error) => {
    console.log(error.message);
  });

delete

Delete a resource. The single parameter is a resource id.

This method returns a promise containing the resource that was deleted.

client.forms.delete('6fc7d1dc-62a4-4c81-a857-6b9660f18b55')
  .then((form) => {
    console.log('success', form);
  })
  .catch((error) => {
    console.log(error.message);
  });

Handling Authentication Errors

The client also provides a registerAuthenticationErrorHandler method which accepts a single parameter, a function to handle authentication errors. Authentication errors will still be thrown but all authentication errors will be sent to the function passed into this method. This is helpful if you've built a client application where a user "logs in" using the getUser and createAuthorization methods (documented below), and for some reason the authorization token has been deleted. This can tell your application to reset the current session and prompt the user to "log in" again. Using this method is optional.

import { Client } from '@fulcrumapp/fulcrum-js';

const handleAuthError = () {
  console.log('The authorization token is no longer valid');
  destroySession();
  promptLogIn();
};

const client = new Client('your-api-token');

client.registerAuthenticationErrorHandler(handleAuthError);

query

The Client object has a query method that can be used to access the Query API. The arguments are a SQL string, and an optional format. The default format is 'json'. Other formats are 'csv' or 'geojson'.

import { Client } from '@fulcrumapp/fulcrum-js';

const client = new Client('your-api-token');

client.query('SELECT * FROM "Manhole Inspections" LIMIT 1;')
  .then(result => console.log(result))
  .catch(error => console.log(error));

// or to get GeoJSON
client.query('SELECT * FROM "Manhole Inspections" LIMIT 1;', 'geojson')
  .then(geojson => console.log(geojson.features[0].geometry.coordinates[0]))
  .catch(error => console.log(error));

getUser

This is a helper function to get user data including organizations you belong to. Use this in conjunction with createAuthorization to create an API token.

import { getUser } from '@fulcrumapp/fulcrum-js';
// or
// const fulcrum = require('@fulcrumapp/fulcrum-js');
// const getUser = fulcrum.getUser;

getUser('[email protected]', 'password')
  .then((user) => {
    console.log(user);
    // user.contexts is an array of the organizations you belong to. Use These
    // ids with createAuthorization to create API tokens.
  })
  .catch((error) => {
    console.log(error.message);
  });

createAuthorization

This is a helper function to create authorizations (API tokens) associated with a user and organization (a membership).

import { createAuthorization } from '@fulcrumapp/fulcrum-js';
// or
// const fulcrum = require('@fulcrumapp/fulcrum-js');
// const createAuthorization = fulcrum.createAuthorization;

const email = '[email protected]';
const password = 'password';
const organizationId = 'organization-id-from-getUser';
const userId = 'optional user id';
const note = 'My awesome app version 4.20';
const timeout = 60 * 60 * 24;

createAuthorization(email, password, organizationId, note, timeout, userId)
  .then((authorization) => {
    console.log(authorization);
    // authorization.token is your API token to use with the rest of the API.
  })
  .catch((error) => {
    console.log(error.message);
  });

Promises

Using Promises, we have more options for flow control and handling errors. In some JavaScript environments we can use the await operator.

The await expression causes async function execution to pause until a Promise is fulfilled, that is resolved or rejected, and to resume execution of the async function after fulfillment. When resumed, the value of the await expression is that of the fulfilled Promise.

In other words, they let us write asynchronous code, where we usually have nested callbacks, in a more sequential pattern. Below is an example of how we would have made two sequential API calls with version 1.

function getFormAndRecord(callback) {
  client.forms.find('abc-123', (error, form) => {
    if (error) {
      callback(error);
      return
    }

    client.records.find('def-456', (error, record) => {
      if (error) {
        callback(error);
      } else {
        callback(null, [form, record]);
      }
    })
  });
}

getFormAndRecord((error, results) => {
  if (error) {
    return console.log(error);
  }

  return console.log(results);
});

And here's an example of using the await keyword to pause execution until the promises (API calls) are resolved.

async function getFormAndRecord() {
  try {
    const form = await client.forms.find('abc-123');
    const record = await client.records.find('def-456');
    console.log(form, record);
  } catch (error) {
    console.log(error);
  }
}

getFormAndRecord();

If either the client.forms.find or client.records.find methods fail, they will be picked up in the catch, allowing us to log errors from a single place and have a much cleaner way of making multiple API calls.

Below is a real world example where we 1) create a changeset, 2) delete a record associated with that changeset, 3) close the changeset. This is similar to how the mobile apps work where all adds, updates, and deletes are associated with changesets.

async function deleteRecord(formId, recordId) {
  try {
    // metadata is an arbitrary object describing the
    // app/environment that the changeset was performed in
    const changesetObj = {
      form_id: formId,
      metadata: {
        app: 'fulcrum-js',
        version: 99.78
      }
    };

    console.log('Creating changeset ...');
    const changeset = await client.changesets.create(changesetObj);

    console.log('Deleting record ...');
    await client.records.delete(recordId, changeset.id);

    console.log('Closing changeset ...');
    await client.changesets.close(changeset.id);

    console.log(`Deleted record ${recordId} in changeset ${changeset.id}.`);
  } catch (error) {
    console.log(error.message);
  }
}

deleteRecord('abc-123', 'def-456');

Media

This library supports creating all media types supported by the Fulcrum API - photos, videos, signatures, and audio. The create method for each of these resource type accepts a Readable Stream and an optional object containing the unique access key for the media.

import fs from 'fs';

const photo = fs.createReadStream('photo.jpg');

client.photos.create(photo)
  .then(created => console.log(created))
  .catch(error => console.log(error));

To specifiy your own access key (unique id) for a piece of media, pass it along in an options object. Otherwise we'll create one for you using the uuid package.

import fs from 'fs';
import uuid from 'uuid';

const photo = fs.createReadStream('photo.jpg');
const key = uuid.v4();

client.photos.create(photo, {accessKey: key})
  .then(created => console.log(created))
  .catch(error => console.log(error));

Since the create method accepts a Readable Stream we can pipe that stream directly from an http request, keeping us from downloading a file and saving it to a temporary file, then deleting it after a successful create.

import request from 'request';

client.photos.create(request('https://nodejs.org/static/legacy/images/logo.png'))
  .then(created => console.log(created))
  .catch(error => console.log(error));

Sometimes you might not have access to a media stream, but will have a Buffer of the entire resource. The library won't be able to infer the file name so you'll need to supply a fileName option.

const photo = fs.readFileSync('photo.jpg');

client.photos.create(photo, {fileName: 'photo.jpg'})
  .then(created => console.log(created))
  .catch(error => console.log(error));

Use the media method to get photos, signatures, audio, and video in multiple sizes. The parameters passed to this method are id (also referred to as access key), and size. The default size is original. The sizes available for each media type are:

Resource	Sizes
Photos	'original', 'thumbnail', and 'large'
Signatures	'original', 'thumbnail', and 'large'
Videos	'original', 'small', and 'medium'
Audio	'original'

Get the original photo size.

const writeStream = fs.createWriteStream('original.jpg');

client.photos.media('4352ac45-8527-43ac-819f-0bc735119767')
  .then(photo => photo.pipe(writeStream))
  .catch(error => console.log(error));

Get the small version of a video.

const writeStream = fs.createWriteStream('vid.mp4');

client.videos.media('5b9b6c9c-2a79-4f69-9539-9c0cb958f0a0')
  .then(video => video.pipe(writeStream))
  .catch(error => console.log(error));

Tracks

Use the track method to get audio and video tracks in multiple formats. The parameters passed to this method are id (also referred to as access key), and format. The default format is json. The other available formats are geojson, kml, and gpx.

Download the track for a video in json format.

client.videos.track('ccf931bd-4e0f-4562-8c00-3a57f8a62589')
  .then(track => {
    fs.writeFileSync('track.json', JSON.stringify(track));
  })
  .catch(err => console.log(err));

Download the track for an audio in gpx format.

client.audio.track('ccf931bd-4e0f-4562-8c00-3a57f8a62589', 'gpx')
  .then(track => {
    fs.writeFileSync('track.gpx', track);
  })
  .catch(err => console.log(err));

Development

Install dependencies:

cd fulcrum-js
npm install

Building

This project uses TypeScript compilation to build ESM and CommonJS outputs:

npm run build       # Build everything (generated client + wrapper)
npm run build:wrapper # Build only the wrapper (src/ → dist/)
npm run clean       # Remove dist/ and generated/dist/ directories
npm run lint        # Check code quality with ESLint
npm test            # Run tests with Jest

OpenAPI Client Generation

The Fulcrum API client is defined in src/ and can be regenerated from the OpenAPI specification.

Updating the Client from OpenAPI Spec

To update the generated client from the latest Fulcrum API specification:

Update the OpenAPI spec (optional, only if the spec has changed):

# Download main spec file
curl -s "https://raw.githubusercontent.com/fulcrumapp/api/spike/power-automate-testing/reference/rest-api.json" > openapi/rest-api.json

# Download external schema files
curl -s "https://raw.githubusercontent.com/fulcrumapp/api/spike/power-automate-testing/reference/components/schemas/ReportTemplateRequest.json" > openapi/components/schemas/ReportTemplateRequest.json

Generate the client from the OpenAPI specification:
```
npm run generate
```
Build the project:
```
npm run build
```
Run tests to ensure nothing broke:
```
npm test
```

How Generation Works

The project uses @openapitools/openapi-generator-cli to generate TypeScript API client code from the OpenAPI specification located at openapi/rest-api.json.

Configuration details:

Generator: typescript-axios
Output: generated/ directory
Package: fulcrum-generated
Module System: Dual build - CommonJS (dist/index.js) and ES Modules (dist/esm/index.js)
Features:
- Full TypeScript support with type definitions
- ES6+ and CommonJS module formats
- Promise-based async/await API
- Axios HTTP client with OTEL support
- 106 TypeScript interfaces/types
- 271+ API methods

Generated package.json exports:

{
  "main": "./dist/index.js",      // CommonJS entry point
  "module": "./dist/esm/index.js", // ES modules entry point
  "typings": "./dist/index.d.ts"   // TypeScript definitions
}

This dual-build approach ensures the client works in both modern (ESM) and legacy (CommonJS) environments.

Manual Customizations

The following custom logic is maintained manually in the src/ directory:

Client.js: Main client class that wraps resource endpoints
Fetcher.js: HTTP client using axios with request queuing
Page.js: Pagination response wrapper
resources/: Resource-specific implementations for each API endpoint
Auth helpers (getUser, createAuthorization in index.js)
Error handling and authentication error callbacks

These manual implementations provide:

A user-friendly API that matches the Fulcrum platform conventions
Request queuing with p-queue (concurrency: 3)
Automatic pagination support via the Page class
Custom error handling and authentication callbacks
Media streaming support (photos, videos, signatures, audio)
Better TypeScript/IDE support with explicit type definitions

Generated Code Integration

When regenerating from the OpenAPI spec, the generated code is placed in the generated/ directory. To integrate new generated APIs:

Review the generated code in generated/
Copy relevant parts to src/resources/ or src/ as needed
Adapt the code to match the existing API patterns
Update src/index.js to export new resources
Add tests for new functionality in test/

HTTP Client

The project uses axios for HTTP requests (as of v2.7.0). Previously it used isomorphic-fetch, but switched to axios for:

Better OTEL (OpenTelemetry) instrumentation support
Automatic request interception
More consistent error handling
Isomorphic support (works in Node.js and browsers)

OTEL Integration

To integrate OpenTelemetry tracing:

import { Client } from '@fulcrumapp/fulcrum-js';
import { BasicTracerProvider } from '@opentelemetry/sdk-trace-node';
import { registerInstrumentations } from '@opentelemetry/auto-instrumentations-node';
import { AxiosInstrumentation } from '@opentelemetry/instrumentation-axios';

// Initialize tracing
const tracerProvider = new BasicTracerProvider();
registerInstrumentations({
  tracerProvider,
  instrumentations: [new AxiosInstrumentation()],
});

// Now all axios requests (including Fulcrum API calls) will be traced
const client = new Client('your-api-token');

Tests

npm test                    # Run all tests
npm run test -- test/test_forms.js  # Run specific test file
npm run lint                # Check code quality

API Verification

To verify the API client against a live Fulcrum account, use the verification script:

npm run verify

This interactive script will:

Prompt you for your Fulcrum API token
Test all available list operations (Forms, Records, Projects, Webhooks)
Display colored output showing success/failure for each endpoint
Print statistics about the responses (count of items, sample data)
Exit with code 0 on success, 1 on failure

Example output:

Enter your Fulcrum API token: ****************************

Writing Tests

Tests are located in the test/ directory and use Mocha + nock for HTTP mocking.

Example:

import { Client } from '../src/index';
import nock from 'nock';

describe('Forms', () => {
  it('should list forms', (done) => {
    const client = new Client('test-token');

    nock('https://api.fulcrumapp.com')
      .get('/api/v2/forms')
      .reply(200, { forms: [] });

    client.forms.all()
      .then((page) => {
        expect(page.objects).to.deep.equal([]);
        done();
      })
      .catch(done);
  });
});

Publishing

To publish a new version to npm:

# Ensure all tests pass
npm test

# Update version in package.json
npm version patch  # or minor/major

# Build the project
npm run build

# Publish to npm
npm publish
