Thank you for your suggestion. While we don't support ActiveCampaign integrations through a prebuilt connector at the moment, it is still possible to integrate to ActiveCampaign using Workato's HTTP connector.
The HTTP connector is generally used for making API calls to applications that we don't formally support (like ActiveCampaign).
You can find out more about our HTTP connector here, and more about ActiveCampaign's API Doc here.
Send us a ticket, we will try our best to assist you with your problem
I suggest that you integrate ActiveCampaign.com
