Can I go back from the WhatsApp API to the Business app with the same number?
Updated 7 October 2026
Only if you remove the number from the API first. After you delete the account to move to the API, you cannot use that number in the Business app again unless you deregister it from Cloud API.
- To use an app number with Cloud API, you either delete your account or onboard through a partner that supports app number onboarding.
- If you delete the account, your existing messaging history is lost.
- Moving through a partner that supports business app number onboarding keeps your history.
Keep ordering the same when you move
Menuthere's WhatsApp ordering runs on your restaurant's own number, and its Order Now button opens the menu already signed in, so moving to the API does not change how customers order.
