Requires iam.credentials.delete on an active principal bound to the authenticated organization. Authenticate with an active, unexpired IAM credential of type api_key. Application API keys (including legacy API keys) and provider OAuth tokens cannot authorize IAM management endpoints. Use an existing IAM credential with these permissions, or create your first management credential in the Dashboard.

Permanently deletes the credential. It can no longer authenticate. A successful response contains request_id and no data.
