API Response Format

This page is under construction.

Postman uses conventional API Responses Codes to indicate the success or failure of an API request.

Response codes do not tell you the delivery status or if your emails are sent. You should be calling the status endpoint.

Code	Description
201	Created. The message is being sent.
400	Bad Request. Failed parameter validations, message is malformed, or attachments are rejected.
401	Unauthorised
403	Forbidden. Request violates firewall rules.
413	Number of attachments or size of attachments exceeded limit.
429	Rate limit exceeded. Too many requests.
500	Internal Server Error. This includes error such as custom domain passed email validation but is incorrect; see here.
