How to create a public API key in systeme.io
In this article, you will learn how to create a public API key in systeme.io.
What are 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, such as contacts and tags. You can have a maximum of two API keys at any given time.
Creating a public API key on systeme.io:
To create a public API key, click your profile picture, select Settings (1), and scroll down to Public API keys (2).

Click Create (3) to start creating a public API key.

In the Create public API key popup, enter a name, and select an expiration date and time for your API key.
Once done, click Save (4).

To choose a specific expiration date and time, select it from the calendar and click Apply.

Note: To keep your API key active indefinitely, leave the 'Expiration' field empty.

Notes:
- To easily identify and manage your tokens, each must have a unique name.
- A token can only be copied immediately after creating it. If you forgot to copy your token, delete it and create a new one.
- As a security measure, we will send you an email notification whenever a new public API key is created in your systeme.io account.
