Build a Whatsapp flow

What is the problem & what have you tried?

Hi, I am building a WhatsApp flow, which works well in several trials. As I keep building, the error started to happen. It keeps saying “Missing value of required parameter ‘to’.”, Then I deleted and rebuilt the same thing, and the error is gone. But it happened to another module. It is so annoying and I don’t know why. Can anyone help? Thank you

Hey there,

This usually means that the number is missing. Can you show a screenshot of how the module is setup?

As Stoyan said, it means no number is being mapped to the “to” section in the WhatsApp Business Cloud module.

If you’re mapping this from previous modules, the issue might lie there.
