Errors

The API uses standard HTTP status codes.

Status	Meaning
200	Success
201	Resource created
400	Bad request — invalid input
401	Unauthorized — missing or invalid x-webhook-signature
404	Resource not found
409	Conflict — e.g. duplicate entry
422	Unprocessable entity — validation failed
500	Internal server error

Error responses include a JSON body:

{
  "statusCode": 400,
  "message": "Validation failed",
  "error": "Bad Request"
}
