This guide shows you how to register your own app with Fathom to obtain your OAuth credentials (client ID & secret). These are required to let your users grant your app access to their Fathom account.
1

Create a Fathom account

If you don’t have a Fathom account, sign up for a free account at fathom.ai.

Register your application

  1. Navigate to the create app form.
  2. Fill in all the required details for your application.
  3. For the Redirect URLs field, add: https://api.nango.dev/oauth/callback
  4. Submit the form to create your application.
  5. After creation, note your Client ID and Client Secret for both production and development environments. You’ll need these when configuring the integration in Nango.
Currently, the only available OAuth scope is public_api.
