We use conventional HTTP response codes to indicate the success or failure of an API request. In general:
2xx indicate success. 4xx indicate an error that failed given the information provided (e.g., a required parameter was omitted). 5xx errors indicate an error with ours servers (these are rare).
Upon a successful send request, our server will respond with a 200 (success) HTTP response code, and you will be provided with a message record which includes our ID.
