Connect your WhatsApp number
Link your WhatsApp Business number so you can send and receive messages.
Before you can send or receive messages, your WhatsApp Business number must be connected to Nezler Connect. Most businesses have this done by the Nezler team during onboarding. If yours is already connected, you'll see a green dot and your number under Settings → WhatsApp connection.

What you need
- A phone number that is not active on the normal WhatsApp or WhatsApp Business app. (Meta can sometimes move an existing WhatsApp Business app number. Ask us to check yours.)
- A Facebook account with access to your business's Meta Business Suite.
- Your business name exactly as you want customers to see it. Meta reviews the display name.
Option 1: let the Nezler team do it (recommended)
Send us the phone number and your business details. We'll register the number with Meta, connect it and test it. You'll receive a 6-digit code on that number by SMS or call during the process; share it only with your Nezler account manager.
Option 2: connect it yourself
- In Meta's WhatsApp Manager, add your number and verify it with the code Meta sends.
- Copy three things from Meta:
- WhatsApp Business Account ID
- Phone number ID
- a permanent access token from a System User in Meta Business Settings
- In Nezler Connect, open Settings. Paste them into the WhatsApp connection box and click Save & verify.
- When the details are right, the box turns green and shows your number and business name.
Click Test connection at any time to check that everything still works.
After connecting
Your approved templates are copied in from Meta automatically. Customers can now message your number, and their chats appear in the Inbox.
