Connect your WhatsApp number
Step-by-step linking for both Coexistence and API-only numbers.
What you'll learn
- Link an existing WhatsApp Business app number with Coexistence
- Link a clean number with API only
- Recover if a new number was registered on WhatsApp by mistake
Have your business website and business email ready before you start (see Create a website and business email for Meta). Meta asks for both.
Coexistence: number already on the WhatsApp Business app
- In StreamHost, select Connect WhatsApp.
- Choose the second option, Connect an existing….
- Enter the business website and business email you created earlier.
- Continue through Meta's setup until a QR code appears.
- On your phone, open WhatsApp Business → Settings → Linked devices → Link a device and scan the QR code.
You can now use the WhatsApp Business app and StreamHost at the same time.
API only: a clean, new number
Do not register the number on WhatsApp before linking it to StreamHost.
- Prepare a new number that has never been on WhatsApp.
- In the StreamHost dashboard, select Connect WhatsApp.
- Choose the first option at every step and follow the setup until it completes.
If the number is already registered on a WhatsApp account, that account must be deleted before it can be linked through the API. Deleting it removes all existing messages and contacts on that account.
Registered the number on WhatsApp by accident? Follow WhatsApp's guide to deleting an account, then link it.
