# Create OAuth credentials

> Creates a reusable OAuth client credential set. Attach it to a webhook by passing the returned id as that webhook's `webhookOauthId`. Several webhooks may share one credential set, so rotating its client secret covers all of them at once. The client secret is write-only and is never returned.

**Endpoint Permissions:** Owner, Admin, Non-Signing Admin.
