OAuth is a supported authentication pattern, but each consent flow must be configured and tested for the exact destination. A successful API-key test does not establish OAuth readiness for a particular AI client.
Identify the two consent relationships#
An AI client may authenticate to an installation or its gateway using a supported first-party sign-in flow. Separately, a server may need OAuth credentials to call an upstream service on behalf of a business account.
These are not interchangeable. An upstream OAuth broker may need provider authorisation and token endpoints, client registration details and scopes. Do not switch an existing API-key connection to OAuth merely because the client offers an OAuth button.
Follow the agreed connection flow#
Use the exact server or gateway address in the handoff. When a browser consent screen opens, check the domain, account and requested access. Authorise only the intended audience and scope using the provider's normal process.
Do not send a callback URL containing an authorisation code to support or paste it into an AI conversation. Keep tokens and client secrets in the supported encrypted configuration route.
Verify after consent#
Confirm that the AI client returns to a connected state, discovers only the intended tools and completes the agreed read-only action in the correct account. Where refresh is part of the configured flow, verify it rather than assuming the initial connection will last indefinitely.
When consent fails#
Record the stage and redacted error. A mismatched redirect address, unsupported registration flow, wrong account, missing scope or expired upstream grant can require different fixes. Do not disable authentication, accept a certificate warning or reuse another person's token as a workaround.
