How to register your own FreeAgent Sandbox OAuth app

Register an OAuth client application with FreeAgent Sandbox and connect it to Tenklo

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

Create a developer account

Go to the FreeAgent Developer Dashboard and sign up for a developer account if you don't have one.

Register your application

  1. Navigate to your Apps page.
  2. Click on the Create New App button.
  3. Fill in the required fields. For the OAuth Redirect URIs, enter https://api.tenklo.dev/oauth/callback.
  4. Submit the form, and your app will be generated. The OAuth identifier will be your Client ID and the OAuth secret will be your Client Secret needed to configure this in Tenklo.
The same application can be used for both FreeAgent production and sandbox environments. The sandbox environment uses api.sandbox.freeagent.com as the base URL.
