What do I need to work with WhatsApp via the Chat API?
The service is very easy to work with. The service is based on WhatsApp Web protocols, therefore, to use the Chat API, you need a phone with the WhatsApp application installed on it, with which you can scan the QR in your personal account and you can start working.
We recommend that our customers stop all other applications on the phone so that WhatsApp does not go into the background, connect the phone to power and a stable network. With the help of such measures, the service will be as stable as possible.
After authorization, the service uploads up to 20 recent messages from each dialog to its database and generates a webhook on them. If you don't need to create a webhook for these messages, then use ignoreOldmessages.
You can unlink your phone number at any time. You can also do this through your personal account.
Through your personal account, you can also clear the instance if you plan to finish working with the service or transfer the instance to another user. Cleaning will delete all data and settings of the instance, and it will fail for a while.
