Lesson
Make can't reply to WhatsApp users with usernames
A Make user runs a WhatsApp Business chatbot. Customers who set a WhatsApp username arrive with a new kind of ID instead of a phone number. Make's Send a Message module rejected the username, and sending to the new ID returned a message ID but nothing was delivered. Replies in the thread suggest calling WhatsApp's Cloud API directly with Make's HTTP module.

The lesson: If your WhatsApp bot replies go missing, check whether those customers use usernames.
Copy this prompt
In my Make scenario, a WhatsApp reply fails when the customer has a WhatsApp username. Look at the incoming message data and tell me which ID field I get. Then explain how to send the reply with Make's HTTP module to WhatsApp's Cloud API instead, step by step, and how to test it with one message.

Watch out for
- A 'sent' status with a message ID doesn't mean it was delivered. Check delivery on a real phone.
