Finally got an example of working with WhatsApp. It's a bit of a pain to setup but this tutorial includes the high-level steps for setting up the connection. You need to create your app at https://developers.facebook.com/ Once you have your app setup, then you need to Set Up WhatsApp so that you can generate an Access Token and get your Test Phone Number, and eventually assign your real phone number. With that setup, you should have everything you need to create both WhatsApp Triggers in n8n and send messages to WhatsApp with n8n. Let me know if you have any questions!
