HeyGen API key. Obtain from your HeyGen dashboard.
Optional client-supplied key for safely retrying mutations. Subsequent calls within 24 hours that share this key replay the original response — even if the request body differs slightly (a warning is logged). A retry that arrives while the original is still in flight gets a 409 request_in_progress. Keys must be 1–255 characters from [A-Za-z0-9_:.-]; a UUID is a safe default. Scope is per-endpoint and per-resource: the same key on a different route or path parameter is independent.
1 - 255^[A-Za-z0-9_\-:.]{1,255}$Webhook endpoint ID
Successful response
Response from rotating a webhook endpoint's signing secret.
