Kit Marketing API: Watch Broadcasts, Add Form Subscriber

About this integration

Creator email marketing — subscribers, broadcasts, and automations.

There are 11 triggers, 24 search modules and 31 actions available. The integration connects via basic or oauth authentication. Webhook-based triggers fire instantly without polling.

How to connect

The credential form asks for API Key, Client ID, and Client Secret.

OAuth asks you to approve read:subscribers, write:subscribers, and read:tags before access is granted.

Sign in and approve access — your password is never shared with WEXTL®, and you can revoke access from the provider at any time.

Enter your credentials below. WEXTL stores them encrypted and uses them only to call the API on your behalf.

You’ll be redirected to sign in and approve access — your password is never shared with WEXTL.

Use it in workflow automation

Start with Watch Broadcasts, then add Add Form Subscriber.

The canvas below runs Watch Broadcasts into Add Form Subscriber — watch the video, then drop a node onto the canvas.

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

Then add Add Form Subscriber as the next node. Branch, filter, or hand off to other integrations from there.

The integration includes 42 ready-made modules for marketing work — each run logs its inputs and outputs for debugging.
