Intelliprint API Reference

Send mail as easily as sending email. With the Intelliprint API, you can send letters and postcards in just a few lines of code.

The API is designed to be REST-ful. Every resource has a predictable URL, and every endpoint accepts data encoded as JSON or multipart/form-data. Responses are JSON-encoded with standard HTTP status codes.

Authentication requires an API key (create one here) in the Authorization header.
