Right now, it sounds like you’ve hit all the possible routes the old on-premise API is gone, the Cloud API register endpoint is deprecated, and even the WhatsApp Manager isn’t auto-approving your number despite everything being verified.

A lot of businesses are running into this issue lately, and it’s definitely frustrating.

One thing that can help is working through an WhatsApp BSP. They typically handle number registration, approvals, and backend setup directly with WhatsApp, bypassing many of the API roadblocks. Plus, many BSPs offer ready-to-use tools like automation, CRM integration, and analytics, which save time and effort.

If you want to avoid the technical back-and-forth, it’s recommended exploring one of the WhatsApp Business API partners.
