What is WhatsApp Embedded Signup?
Embedded Signup is a browser-based interface supplied by Meta that authenticates a Facebook user, creates (or links) a WhatsApp Business Account (WABA), adds a phone number, and returns production credentials in one flow. Chatwoot Cloud embeds this interface when you choose WhatsApp Cloud while adding an Inbox, so no manual tokens or webhook URLs are required.
