Is it possible to save the WhatsApp or WhatsApp Business App number when switching to the WhatsApp Business API?

If the number is already connected to WhatsApp and WhatsApp Business App, then this number can also be used in the WhatsApp Business API, but for this you need to delete the account in the WhatsApp messenger.
The WhatsApp\WhatsApp Business App and WhatsApp Business API application number databases are separate databases from each other. If the number is in the WhatsApp application database, then it cannot be used in WABA and vice versa. That is why before you start connecting the number, you need to delete the account in the messenger.
The emigration process itself may take some time. If you need to connect the API urgently, then we offer to read the article – which number is suitable for connecting the WhatsApp Business API?
If you want to transer the number, the procedure will be as follows:
1-Delete your WhatsApp account or WhatsApp Business App via the account settings in the app. Without deleting an account in WhatsApp apps, switching to the WhatsApp Business API is not possible;
3-Register in the Chat API/ Registration with deferred verification it will allow you to connect a WABA number in just 5 minutes.
Important! During the emigration process, all incoming messages will be saved on WhatsApp servers and will come to you after the transition is completed. It is worth downloading the previous history of correspondence in advance, since it will not be saved during emigration.
And that's it. If you have any questions about emigration, feel free to write to our support – we will help. Good luck!
