Authentication
All calls to the Docusign Agreement Desk API are authenticated using an access token that your app obtains using one of the standard OAuth 2.0 grants supported by Docusign:
Note: See Choose an OAuth type for details on when to use each authentication type.
The only difference between authenticating with the Agreement Desk API and the eSignature API is that, when requesting the access token in your OAuth2 scenario, you must request special Docusign Agreement Desk scopes in addition to your other Docusign eSignature Authentication scopes.
Important: If the required Docusign Agreement Desk API scopes were not explicitly requested, calls to the Docusign Agreement Desk API will fail.
