Issue with AuthKitToken.create()

[onemansempire]

I'm implementing AuthKit in my application following your documentation at https://docs.picaos.com/authkit/setup, but I'm encountering an "Authentication service error" when users try to connect integrations through the AuthKit modal.

Setup Details:

• Using @picahq/authkit-node (latest version) in a Supabase Edge Function (Deno environment)
• Using @picahq/authkit frontend SDK in React
• Slack integration is configured and marked as "Visible in AuthKit" in my Pica dashboard
• Slack OAuth app is properly configured with redirect URI: https://app.picaos.com/connections/oauth/callback
• API key is valid and working (51 characters)

The Problem:

When I call AuthKitToken.create() as documented, it's returning a list of connection definitions instead of a link token:

{
  "rows": [
    {
      "id": 525637,
      "connectionDefId": 11,
      "type": "api",
      "title": "Slack",
      "image": "https://assets.picaos.com/connectors/slack.svg",
      "activatedAt": "2025-10-08T21:12:20.156442",
      "secretId": "0510a9dc-09f2-4234-af57-ebc1efc0aa26",
      "clientSecretDisplay": "dddd...d",
      "clientIdDisplay": "9659444955701.9663269274290",
      "scopes": "...",
      "environment": "test",
      "active": true
    }
  ],
  "total": 1,
  "pages": 1,
  "page": 1,
  "requestId": 33862
}

Expected Behavior:

According to the documentation, AuthKitToken.create() should return a link token in a format like:

{
  "linkToken": "...",
  "identity": "user-id",
  "identityType": "user",
  "expiresAt": "..."
}
My Code:

// Backend (Supabase Edge Function)
import { AuthKitToken } from 'https://esm.sh/@picahq/authkit-node@latest';

const authKitToken = new AuthKitToken(picaApiKey);
const tokenData = await authKitToken.create({
  identity: userId,
  identityType: 'user',
});
// Returns connection definitions instead of link token
// Frontend (React)
import { useAuthKit } from '@picahq/authkit';

const { open, isLoading } = useAuthKit({
  token: {
    url: `${supabaseUrl}/functions/v1/authkit-token`,
    headers: {
      'Authorization': `Bearer ${accessToken}`,
      'apikey': supabaseAnonKey,
    },
  },
  onSuccess: (connection) => {
    console.log('Connected:', connection);
  },
  onError: (error) => {
    console.error('Error:', error); // Shows "Authentication service error"
  },
});

Debugging:

When I log the available methods on the AuthKitToken instance:

Object.getOwnPropertyNames(Object.getPrototypeOf(authKitToken))
// Returns: ["constructor", "_clientInfo", "_url", "create"]

The create() method exists, but it seems to be calling the wrong internal API endpoint (possibly /connections/definitions instead of a link token endpoint).

Questions:

• Is AuthKitToken.create() the correct method for generating link tokens?
• Is there a different method or SDK version I should be using?
• Could this be related to using the SDK in a Deno environment (Supabase Edge Functions)?
• Is there a direct Pica API endpoint I should call instead of using the SDK?

Environment:

• Runtime: Deno (Supabase Edge Functions)
• SDK Import: https://esm.sh/@picahq/authkit-node@latest
• Frontend: React with @picahq/authkit
• Account Type: Free tier (test environment)

I'd really appreciate any guidance on how to properly generate AuthKit link tokens. Happy to provide more logs or debugging information if needed!

Thank you for your help!
