New Subscriber gets a message

What are you trying to achieve?

I am trying to build an automation so that when a new subscriber is listed in my ConvertKit account, they receive a message via WhatsApp or SMS.

Steps taken so far

I have already connectet all the API’s for ConvertKit and Twilio, but I have no Idee how to continue

Show us the scenario and the step where you’re stuck.

So my first step is from ConvertKit (watch subscriber activated), and the next step is Twilio (create a message).

The problem is that I don’t know how to automate it so that it takes the new phone number of the subscriber and sends them a template message.
