API Access Authentication Method Settings
The API Access method issues client credentials for programmatic access: each client is a Client ID and Client Secret pair associated with a user account, which external systems use to obtain access tokens.
To add it, go to the Authentication tab, select Add and choose API Access.

The editor shows the list of API clients, with their Client ID, User Account, Validity, and Expiration. Use Add, Edit, and Remove to manage them.
