Hi everyone,

I'm dealing with a very frustrating issue with WhatsApp Cloud API setup and I wanted to ask if anyone here has gone through the same thing.

My business was successfully verified, but I still cannot complete the WhatsApp Cloud API onboarding process.

The problem is not just about access tokens. I am also unable to register the phone number in the Meta interface itself.

These are the errors I keep getting:

• "An error occurred while registering your phone number"
• "This page is not available at the moment. Please try again in a few minutes."
• sometimes it also says the phone number is invalid

What makes this worse is that the issue happens directly in Meta's setup interface, so it does not seem to be just an API request formatting problem.

Things I already tried:

• reconfiguring 2FA
• setting a valid 6-digit PIN
• deleting and recreating the test phone number
• adding another user to the Business Manager
• trying different browsers
• testing with another user profile
• creating a completely new app
• repeating the setup from scratch

I also checked Meta Status and noticed there was an incident/disruption affecting Meta business services, so now I am not sure whether this is:

1. a platform-side issue, or
2. some hidden restriction/block on my personal profile, Business Manager, or WhatsApp Business Account

Support already gave me a generic AI-style response and then closed my ticket without actually resolving anything.

Has anyone experienced this exact problem before?
Did it fix itself after some time, or did you have to contact a specific team/forum to get it solved?

Any help would be really appreciated.
