Use it in workflow automation

Start with Watch Contacts, then add Add a Contact to a Group.

The canvas below runs Watch Contacts into Add a Contact to a Group — watch the video, then drop a node onto the canvas.

Select the Watch Contacts trigger and the workflow fires automatically when the event occurs — no polling required.

Then add Add a Contact to a Group as the next node. Branch, filter, or hand off to other integrations from there.

The integration includes 12 ready-made modules for communication work — each run logs its inputs and outputs for debugging.
