From what is see they want an XML post. which i assume is a TEXT Data type in the API Server Action.
But how do i generate the loop of phone numbers as they want there.
And also catch the error message.
Haven’t looked at the docs/links, but seeing the words XML POST pretty much means it can’t be done with default Wappler components.
Custom module (PHP & NodeJS) or custom code (ASP.NET) is the only option.
