Embedded signup
Meta’s in-product flow for connecting a WhatsApp Business Account to a platform without leaving it.
Embedded signup is the guided window where you sign in with Facebook, pick or create a WABA, register the phone number and grant the platform access — all without hand-copying tokens between dashboards.
It is also where you choose between coexistence and full migration. A platform that cannot offer that choice at this step cannot offer coexistence at all.
