How to use the systeme.io public API (Application Programming Interface)

In this article, you will learn how to configure and use the systeme.io public API, including how to generate API keys and what actions you can perform.

1. What is an API?

The acronym API stands for "Application Programming Interface", a series of instructions by which a platform offers services to other platforms. It's a strategic gateway for external developers, enabling them to access specific functionality or data from a platform in a structured, secure way. It's like a set of ready-to-use tools that make it easy to build new applications, services, or combinations.

In short, systeme.io opens up to other platforms to offer its services where it has added value.

2. How does our public API work?

Our API exposes a carefully selected set of features, enabling developers to interact with our platform transparently and efficiently. If you'd like to know more about how it works, you can read our official API documentation.

3. How to generate your API keys

API keys are unique identifiers that authenticate requests to our Public API. They enable you to programmatically access and manage various resources on our platform.

To connect an external integration, you first need to generate a secure API key. Click on your profile picture and select Settings (1). In the left menu, click MCP & API keys (2).

Scroll down to the Public API keys section and click Create (3).

Give your key a name, set an expiration date, and click Save (4).

Your key is now ready.
