This guide will walk you through how to integrate ActiveCampaign with systeme.io.
Important note: This integration is not mandatory. If you want to use email marketing in systeme.io, you can do it for free using our built-in autoresponder.
To get started, you will need the following:


Ensure your API is enabled in ActiveCampaign. If you haven't enabled your API, please refer to this ActiveCampaign article to learn how to enable it and generate your API URL and Token.
Once your API is enabled, activate the integration by checking the Activate box. Enter your API URL and API key in the corresponding fields, then choose your desired triggers.
Finally, click on Save to start the integration.

This integration supports three triggers:
Contacts and their associated systeme.io tags will be synchronized with your contact list in ActiveCampaign.
Notes:
- This is a one-way integration, meaning that changes made to your contact list within ActiveCampaign will not be reflected in systeme.io.
- If you reset your API key in ActiveCampaign, remember to update it in your systeme.io settings as well.
