WhatsApp with a new phone number
Use this path when the number is not registered on WhatsApp yet. If the same number already runs the WhatsApp Business App, use the existing-phone guide instead.
In the app: Setup → Channels → WhatsApp
Get a number if you do not have one
The number must be able to receive a voice call for Meta verification. SMS OTP is not supported in this flow.
- If you need a new line, buy one in CoPulse under Setup → Channels → Phone (wallet top-up required; promo credits cannot buy a number).
- Wait until the phone channel shows the number as ready.
- Return to WhatsApp setup and continue below.
Onboarding steps in CoPulse
- Contact email — enter a real inbox, confirm the checkboxes, click Start onboarding. Gupshup OTP and later Meta voice OTP go here.
- Verify OTP — paste the 6-digit Gupshup email code and click Verify OTP.
- Meta signup — open the Gupshup popup, Continue with Facebook, select or create a Business portfolio and WhatsApp Business account.
- On Add a number, choose Add a new number, enter country code, number, and display name.
- Select Phone call — not Text message. CoPulse shows a sticky banner and emails the code to the Step 1 address.
- Enter the 6-digit voice code, confirm permissions, then click Finish on Facebook.
- Stay in Gupshup and click its last Continue / Finish. Do not close Gupshup after Facebook says you are connected.
- Return to CoPulse and continue to Go live.
Do not
- Select Text message / SMS for number verification.
- Close the CoPulse tab or the Gupshup window before Gupshup’s last Continue / Finish.
- Remove Gupshup as a partner in Meta Business Manager after connecting.
Then test
After go live, use Chat on WhatsApp and Settings → Try this channel. Settings (greeting, widget, templates) are explained on Connect WhatsApp.
FAQ
Why must I choose Phone call instead of SMS?
CoPulse can display and email the voice OTP. SMS OTP is not wired into this onboarding, so verification will stall if you pick Text message.
