You can create an OAuth2 application if you want to grant a third-party application access to your account. Here’s how to do that once you have a Coinbase.com account:
Sign in to your account and access the profile menu from your account dashboard.
Choose Settings from the drop-down menu.
Select the API tab. You can create an OAuth2 application by selecting + New OAuth2 Application.
Fill in the necessary information for the OAuth2 application form. Some of the information that you’ll be asked for includes:
the Application Name.
You will not be able to rename your application after it has been created.an optional Website that will serve as your application’s homepage.
a Description of your application.
an icon for your application.
a list of Permitted Redirect URIs.
an optional Notification URL that serves as your webhook for notifications.
If you have questions about the information that the OAuth2 application is requesting, the application form provides links to relevant developer documentation. You can also access developer documentation here.
Select Create Application.
You’ll be provided with your Client ID and Client Secret. The final page of the application process will give you this new information as well as providing a summary of information that you provided in the application form.
