is is mandatory to have a official facebook developer account for whatsapp api?

for my SaaS I would need a whatsapp notification system but I don't want to create the developer account. I wanted a simple api to call. I have found some platforms doing it but this is supposed to be a scam. because they wanted to scan a qr to get access to my whatsapp. do you know any alternative APIs which will give me a number and also send a message. submitted by /u/khila
