Using OAuth 2.0 Authentication
Extending the functionality of Tempo to integrate with external systems or users requires the Tempo Administrator, Jira Administrator, Tempo Team Administrator, and Tempo Account Administrator permissions.
Integrators can use OAuth 2.0 to provide secure authentication for access to Tempo data.
To generate credentials for access to Tempo data:
Select Settings  in the Tempo sidebar.
Under Data Access, select OAuth 2.0 Applications.
Enter Name, Redirect URLs, and Client Type.
Enter Authorization Grant Type. You will typically select Authorization code as the Authorization grant type.
Click Add. Your named credentials are generated and added to the page.
Under Actions, click the Information icon to display the Credentials dialog.
Click the Copy icon to the right of the Client ID or Client secret to copy it to the clipboard. You can obtain an access token for your application, and then make requests to the Tempo REST API.
To revoke credentials for access to Tempo data:
Select the credentials you want to revoke.
Click Delete.
Refer to the Tempo REST API documentation for information about how to retrieve, restore, and revoke an access token. For detailed information about OAuth 2.0, consult their specification at https://oauth.net/2/ .
