Use it in workflow automation

Start with Watch Events, then add Create a Lipdub.

The canvas below runs Watch Events into Create a Lipdub — watch the video, then drop a node onto the canvas.

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

Then add Create a Lipdub as the next node. Branch, filter, or hand off to other integrations from there.

The integration includes 8 ready-made modules for marketing work — each run logs its inputs and outputs for debugging.
