We know that Facebook is eventually planning to integrate WhatsApp into Facebook’s other apps as well. As reported by the WABetaInforeverse-engineering of @Alex193a has found evidence of this in the latest version of Facebook Messenger. The following table shows the message of “whats_app” references.
This can be a pre-cursor to the long process of the integration of the Facebook Messenger and WhatsApp users. The main difference between the two messaging platforms that WhatsApp stores the chat information in the device, in addition to the end-to-end encryption, along with the ad-free). This is the reason why I write is only allowed to be used on a single device.
The point of the references to the tables in a local database, to Facebook messenger, which are necessary for the administration of the messaging and related services. There are also mentions of other elements that will make it possible to use the Facebook Messenger to know what the WhatsApp users are to be blocked, the push notification of WhatsApp, and the details of the chat box.
