Hello @francoisjacquet , Please could you explain the new gateway, WhatsApp Cloud API.
There is indeed a new gateway, the WhatsApp Cloud API for the SMS Premium module.
Here is the help:
WhatsApp Cloud / Business API. First 1000 conversations each month are free. For configuration, please enter the access token in the API key field and your from phone number ID in the API username field. Error codes and possible solutions.
Here is the setup link: https://developers.facebook.com/docs/whatsapp/cloud-api/get-started
In other words, this is a way to send messages to WhatsApp from RosarioSIS.
Oh, one thing, I was not able to test it myself as I do not want to create an account at Meta/Facebook for privacy reasons.
Please let me know here if you have any issue with the WhatsApp API.
