Unable to Add WhatsApp Number — Meta Docs Say Migration Possible Without Deletion (Need Clarification

Status: Open · Asked by sdwivedi on · 0 views

sdwivedi — Question ·

Hi Team,

I'm trying to add my WhatsApp number to Pabbly ChatFlow, but I keep getting this error on the Facebook Business onboarding screen:

“This phone number is already registered to a WhatsApp account. To use this number, disconnect it from the existing account.”

Screenshot attached.

However, Meta’s latest documentation (Updated Oct 31, 2025) mentions that it IS possible to migrate an existing WhatsApp Business App number without deleting it if the onboarding is done through a Solution Provider who supports Business App Number Onboarding.

Here is the reference page from Meta Developers:
https://developers.facebook.com/documentation/business-messaging/whatsapp/solution-providers/migrate-existing-whatsapp-number-to-a-business-account

According to Meta’s docs:


  • If the number is a regular WhatsApp Messenger number, deletion is mandatory.
  • If it's a WhatsApp Business App number:
    • You can delete the account and migrate — but you’ll lose chat history.
    • OR
    • You can migrate without deleting, IF your Solution Provider supports Business App Number Onboarding.
  • With this supported migration:
    • Chat history is preserved
    • The number can work simultaneously with:
      • WhatsApp Business App
      • The Solution Provider’s platform

This is exactly what I want.

❓ My Question for Pabbly ChatFlow Team


Does Pabbly ChatFlow support WhatsApp Business App Number Onboarding as defined by Meta?

Specifically:

  1. Can I migrate my existing WhatsApp Business App number without deleting it?
  2. Does Pabbly support the partner-level migration flow that preserves history and avoids the “disconnect number” requirement?
  3. If yes, what is the correct onboarding process inside Pabbly?

Right now, the onboarding flow forces me to delete my existing WhatsApp Business app account, which doesn't match Meta’s documented capability for partner onboarding.

Why This Is Important


Deleting the number causes:
  • Total loss of WhatsApp Business App chat history
  • Required downtime
  • Inability to use the Business App again unless deregistered from Cloud API

But according to Meta, with supported partner onboarding, none of this is required.



Would appreciate clarification from the Pabbly team:

? Does Pabbly ChatFlow support the no-deletion migration path?
? If yes, can you provide the correct steps?
? If not, is this feature planned?

Thanks! ?
