# Flatfile Company Validation Plugin
2+
3+
This plugin implements a company validation RecordHook for Flatfile. It validates company information including name, website, address, and EIN (Employer Identification Number). The plugin uses external APIs for address validation and EIN verification, providing detailed error messages for unverified information.
4+
5+
## Features
6+
7+
- Validates company name
8+
- Validates company website format
9+
- Validates company address using Google Maps API (optional)
10+
- Validates EIN using EIN Verification API (optional)
11+
- Configurable validation options
12+
- Detailed error messages for invalid data
13+
14+
## Installation
15+
16+
To install the plugin, run the following command:
17+
18+
```bash
19+
npm install @flatfile/plugin-company-validation
20+
```
21+
22+
## Example Usage
23+
24+
```javascript
25+
import { FlatfileListener } from "@flatfile/listener";
26+
import companyValidationPlugin from "@flatfile/plugin-company-validation";
27+
28+
const listener = new FlatfileListener();
29+
30+
listener.use(
31+
companyValidationPlugin({
32+
sheetSlug: "companies",
33+
googleMapsApiKey: "YOUR_GOOGLE_MAPS_API_KEY",
34+
einVerificationApiKey: "YOUR_EIN_VERIFICATION_API_KEY",
35+
validateAddress: true,
36+
validateEIN: true,
37+
})
38+
);
39+
```
40+
41+
## Configuration
42+
43+
The plugin accepts a configuration object with the following properties:
44+
45+
- `sheetSlug` (string): The slug of the sheet to apply the validation to
46+
- `googleMapsApiKey` (string): Your Google Maps API key for address validation
47+
- `einVerificationApiKey` (string): Your EIN Verification API key
48+
- `validateAddress` (boolean): Whether to validate company addresses
49+
- `validateEIN` (boolean): Whether to validate EINs
50+
51+
## Behavior
52+
53+
The plugin performs the following validations:
54+
55+
1. Company Name: Checks if the name is longer than 1 character
56+
2. Company Website: Validates the website format using a regex pattern
57+
3. Company Address (optional): Uses Google Maps API to verify the address
58+
4. EIN (optional): Verifies the EIN using the EIN Verification API
59+
60+
For each invalid field, the plugin adds an error message to the record. The record is then returned, allowing Flatfile to display the errors to the user.
61+
62+
Note: Address and EIN validations are performed only if the respective configuration options are set to true.
