Basecamp OAuth 2.0 connector profile – StackOne setup guide

You must have access to register applications on the 37signals Launchpad. This is typically available to account administrators or developers.

Register an OAuth Application

Create an OAuth 2.0 application on the 37signals Launchpad to obtain your API credentials.

Access the Launchpad Integrations Page

Navigate to 37signals Launchpad and sign in with your Basecamp account.

Create a New Application

Click Register another application to begin creating a new OAuth application.

Complete the Application Form

Navigate to the application form and fill in the required details.

Name of your application: Enter a descriptive name (e.g., StackOne Integration App)
Your company’s name: Enter your organisation name
Your website URL: Enter your company website URL
Products: Select the Basecamp 5 product from the list
Redirect URI: Use https://api.stackone.com/connect/oauth2/basecamp/callback

Copy Your Credentials

Once registered, click your application name to view the credentials.
