Creating a Custom OAuth Application

A custom OAuth application is required to authenticate on Desktop applications, Web applications, or Headless machines while using the REST API.

To register an OAuth application and obtain the OAuth client credentials, the Client Id, and Client Secret:

1. Log in to your PayPal developer account.
2. Navigate to My Apps & Credentials (under Dashboard).
3. Scroll to the REST API apps section.
4. Click Create App.
5. Specify a name for your application.
6. From the drop down list, select the sandbox account from which data will be retrieved.

PayPal generates a set of sandbox and live OAuth keys for the application. The sandbox credentials display after the application has been created. To see the live credentials, select the Live option.

The sandbox credentials are used to get data only for the sandbox account you selected while creating the application. The Live credentials are used to get data only for the developer account that was used to create this application.
