Automatic Letter Printing and Mailing API
Intelliprint lets you easily create, send, and track letters for your business. Automate the process for future campaigns and get more done with less effort.
The Intelliprint API is designed with a simple and predictable URL structure that makes it easy to use.
Every endpoint accepts request bodies encoded as JSON, or with form encoding.
Responses are JSON-encoded, with standard HTTP status codes.
For authentication, we use API keys provided in the Authorisation header using HTTP Bearer authentication.
