Add Client ID to Domains

POST

/domains/add-client-id

Registers an OAuth client ID on one or more domains for a third-party integration.

The clientId is validated against the target app before being applied. If the app name you provide doesn't match the client ID exactly but is a substring of the registered name, the API will use the official app name automatically.
