Connect the official WhatsApp Business API (Embedded Signup)
Advertz connects your number to the official WhatsApp Business API through Meta’s Embedded Signup. Your WhatsApp Business Account stays in your own Meta Business portfolio, and Meta bills message charges to your own payment method.
Before you start
- A phone number that is not currently active on the WhatsApp or WhatsApp Business app (or Meta’s coexistence option where it is available)
- Admin access to your business’s Facebook / Meta Business portfolio
- Your business’s legal name and website
Connect your number
- Go to WhatsApp → Link Meta WhatsApp and start the connection.
- Log in with the Facebook account that manages your Meta Business portfolio.
- Select or create your business portfolio and WhatsApp Business Account.
- Enter your phone number and verify it with the code sent by SMS or voice call.
- Set the display name customers will see.
When the flow finishes, the number appears as connected and you can send and receive messages from the Inbox.
After connecting
- Add a payment method in Meta (WhatsApp → WhatsApp Billing shows how) so template messages can be delivered.
- Complete Meta Business Verification to raise your messaging limits.
- Already have templates in Meta? Use WhatsApp → Import from Meta.
