How to Connect Your WhatsApp Business Number to a Shared Team Inbox

The steps to connect a WhatsApp business number to Nexus through Meta’s official window, what to prepare first, and what happens to your number afterwards.

What to prepare before you start

Have a number you are entitled to use and a Facebook account that can manage your business at Meta. The number can be new or one already used in the WhatsApp Business app, because Meta offers a mode that lets the phone app keep working alongside Nexus (Coexistence).

Business verification at Meta affects your sending limit and display name. You can start without waiting for it, but the number of new customers you can reach per day stays smaller until your business is verified.

Connecting through Meta’s window

In Nexus, open the Channels screen and choose to connect WhatsApp. Meta’s own sign-up window (Embedded Signup) opens: you sign in with your Facebook account, pick or create a WhatsApp Business account, enter the number, and enter the verification code Meta sends to it. Nexus never sees that code.

When it finishes, Nexus gets access to that business account and starts receiving incoming messages. You can invite agents, set how chats are shared out, and reply from one shared inbox.

Message fees and the payment card

WhatsApp message fees are paid straight to Meta through the payment method on your WhatsApp Business account, not through Nexus. Attach the card at Meta before sending templates; without an active payment method, templates are not delivered.

You can disconnect the number from Nexus at any time. Disconnecting stops new messages reaching Nexus and does not delete your WhatsApp Business account at Meta.

Limits

Business verification, display-name approval and sending limits are decided by Meta, not by Nexus. Nexus shows their status but cannot speed them up.
