Download the maintained Postman collection, or import that URL directly into Postman. The relative download path continues to work if the documentation moves to a custom domain. Set the collection variables:
  • api_key: your server-side Production key.
  • email_id: an email returned by POST /v1/emails.
  • message_id: a message returned by the list operation.
  • attachment_id: an attachment listed on a message.
The collection includes exactly the eight public v1 operations and contains no polling or test scripts. The Create email request uses Postman’s dynamic GUID to produce a fresh idempotency key.
The collection contains no API key or Postman environment. Store real API keys only in your private local environment and never commit or share them.
