Webhook not configured

Course watches require an enabled webhook destination.

Resolution

Configure and enable your webhook in the developer portal.

Response handling

Keep the response's request_id for diagnostics. Retry only transient rate limits and 503 responses, respecting Retry-After with bounded exponential backoff and jitter. For monthly_quota_exceeded, stop polling until RateLimit-Reset or upgrade. Correct 400, 401, 403, and 406 requests before retrying.
