Get started with the Make API

At Make, we develop newsletter and SMS software for marketing and communication. If you are looking for documentation on how to get started or in need of assistance, then head over to our support section.

API reference

If you just want to jump straight into the reference documentation, that can be found here:

API overview

All of our endpoints are organised around RESTful principles, and we follow the OpenAPI Specification. This allows us provide Web-based interactive documentation which you can use to browse and interact with our API endpoints from the comfort of your Web browser.

API limitations

There's currently a limit of 10.000 on each bulk insertion. Please conform to this principle to avoid a 422 unprocessable entity response.

Before you start

Here are a few things to know before you start.

You need to have a Make account to access resources from our API. If you don't have an account yet, you can sign up for a free demo over on our homepage.


To authenticate and authorize API calls we use Basic HTTP Authentication. Under the API Settings section of your Make account you can find credentials needed for that authentications. Userid should be used as a username, and APIKey as a password.
