Connect your WhatsApp number

MeAPI connects your number through Meta’s own Embedded Signup — a Facebook pop-up where you choose your business and verify the number. MeAPI never sees your Facebook password.

What you need

• A Facebook account that can manage your business (or create one during signup).
• Your business name, website (or social page) and category.
• A phone number that can receive an SMS or voice call for verification, or the number you already use in the WhatsApp Business app (see Coexistence).
• A number on the regular WhatsApp (not Business) app must be deleted from that app first — or use coexistence after moving it to the WhatsApp Business app.
• No Facebook Page and no business verification needed to connect (unverified businesses start with lower messaging limits); the popup adds the number to your business itself.

Steps

1. Log in at login.meapi.in and open Connection.
2. Choose how to connect:
   • Connect a new number — a number not in use on WhatsApp. It will run on the API only.
   • I already use the WhatsApp Business app on this number — keep the app (coexistence).
3. In the Facebook pop-up, log in and select or create your Meta Business portfolio.
4. Create or select a WhatsApp Business Account and enter the display name customers will see. Meta reviews display names; keep it the same as your business or brand name.
5. Add and verify the phone number with the code Meta sends by SMS or call (for coexistence: scan the QR code shown, from the WhatsApp Business app).
6. Back in MeAPI, the number shows as Connected. Under My Numbers you can see its quality rating, messaging limit and name status.

Note

Meta charges for template messages are billed to the WhatsApp Business Account. Add a payment method in Meta’s WhatsApp Manager → Payment settings before sending business-initiated templates, or they may fail.

After connecting

• Templates: create some under Templates, or pick from the library — Meta reviews each one.
• Verify your business in Meta Business Settings to raise your messaging limit and to qualify for the official business account badge later.
• Invite your team under Agents, and connect more numbers the same way if your plan allows.

Troubleshooting

Problem	Fix
Pop-up closes without connecting	Allow pop-ups for login.meapi.in and try again; finish every step in the pop-up
“This number is already registered”	It is still on a WhatsApp app — delete it there, or use coexistence if it is on the Business app
No verification code	Choose voice call instead of SMS; landlines must use voice
Display name rejected	Use the exact business name shown on your website or documents
