Embedded Signup is Meta’s embedded flow that lets a business authorize and connect its WhatsApp Business Account / number to a partner solution (e.g. Tech Provider) in a few browser steps.

It cuts friction versus long manual onboarding. In 42agents the agency’s client completes Embedded Signup; the agency does not invent a parallel OAuth.
