When using the SEND MESSAGE API from the GHL API 2.0, if the fromNumber is a number bought in GHL the system works properly, it returns a 201 status and the messages gets to the whatsapp destination number.

But if the business whatsapp number has been imported from meta and not directly bought on GHL, the API fails with a 400 error, specifically: "Request failed with status code 404"

It would be great to be able to send WA messages via API even with imported WA numbers.
