Create an app to get credentials and use these credentials to authenticate when you make REST API requests.

 

1. Go to My Apps & Credentials. Click Log In.

2. In the REST API apps section, click Create App.

3. On the Create New App page, enter an app name, select your sandbox developer account, and click Create App.

4. The Sandbox tab shows your client ID. Click Show to show your secret. Note your client ID and secret. You'll need these values later.
