How to setup a WhatsApp channel (Embedded signup)

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. VowChat embeds this interface when you choose WhatsApp Cloud while adding a Channel, so no manual tokens or webhook URLs are required.

Prerequisites at a glance

• Facebook (Meta) login

• Business information

• VowChat workspace with WhatsApp feature enabled

Onboarding workflow inside VowChat

Step 1. Go to Settings → Channels → "Add Channel". Select WhatsApp.

Step 2. Click on the "Connect with WhatsApp Business" button.

Step 3. Start Meta flow. Log in with the Facebook account that will manage the WABA. Provide business details or pick an existing portfolio, then choose an existing WABA or create a new one.

Step 4. "Add agents" to your WhatsApp channel.

Tip: Use a dedicated browser tab and disable ad-blockers; Meta's OAuth windows rely on third-party cookies

Compliance checkpoints

1. Business verification: Upload legal documents if Meta prompts during or after signup

2. Display name review: Ensure the WhatsApp display name matches branding guidelines to prevent rejection
