The following document explains how to set up auto-fill for the application credentials in ActiveDocs: https://access.redhat.com/documentation/en-us/red_hat_3scale/2.1/html/api_documentation/create-activedocs-spec#useful_tools

It mentions only app_ids, app_keys or user_keys.

As part of the implementation for this RFE: https://github.com/3scale/system/issues/8422 two additional values were added: client_ids and client_secrets.

So, the functionality of the x-data-threescale-name values is currently as follows:

• user_keys return only the credentials of the applications for services that are using API key authentication mode.
• app_ids and app_keys return the credentials of the applications for services that are using App Id / App Key or OAuth authentication (including OpenID Connect) – they are not excluding OAuth / OpenID Connect for backwards compatibility.
• the new client_ids and client_sercrets value are used to return only the credential of the applications for the services that use OAuth and OpenID Connect authentication mode.

This needs to be documented.
