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 the WhatsApp and WhatsApp Business App applications, then this number can also be used in the WhatsApp Business API, but for this you will need to use the number emigration procedure.
To understand the essence of the emigration process, we can imagine that the WhatsApp\WhatsApp Business App and WhatsApp Business API application numbers database are separate databases from each other. If the number is located in the WhatsApp application database, then it cannot be used in the API and vice versa. Emigration transfers a number from one database to another.
The emigration process itself may take some time. If you need to connect the API urgently, then we offer you an article - which number is suitable for connecting the WhatsApp Business API?
If you want to save the number, the procedure will be as follows:
1-Write us the phone number that you want to submit to the emigration procedure;
2-Delete your WhatsApp account or WhatsApp Business App via the account settings in the app;
3-Register in the Chat API (if you have not been registered yet) and go through one of two registration methods – Classic or Registration with deferred verification.
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.
