Anyone know an API-first WhatsApp Cloud API calling solution that's dead simple? I'm trying to dodge Meta's labyrinth of docs. This is purely for voice calling - no messaging needed. Every solution I find seems built for messaging first, and the calling side is either bolted on or buried in jargon. Ideally something with a clean endpoint, minimal setup, and no certification drama. CPI optimisation is my day job, so I need to test this quickly without getting lost in verification loops. Thoughts?
