Problem
I am a registered WhatsApp Tech Provider and I'm trying to onboard my own business phone number using the Coexistence feature (WhatsApp Business App onboarding via Embedded Signup).
During the Embedded Signup flow, when I reach the business portfolio selection screen, my own portfolio is grayed out with the message:
"This business portfolio owns Developer APP. You can only select other business portfolios."
This means I cannot select the portfolio that owns my app to onboard my own production WhatsApp Business App number.
What I've tried
- Selecting other business portfolios — these belong to other businesses and I don't want to use them
- Looking for a pure API approach to trigger Coexistence without Embedded Signup — doesn't seem possible since the WBA ↔ Cloud API linking requires the Embedded Signup UI flow
Question
Is there a supported way for a Tech Provider to onboard their own production WhatsApp Business App phone number to Cloud API with Coexistence enabled, without using a third-party business portfolio?
