WhatsApp Encryption
WhatsApp messages are encrypted from tyntec to the device, and secured over HTTPS (and optional SSL/VPN) from your application to tyntec.
In addition to high-level encryption, WhatsApp also displays a security message at the start of the chat. This helps make sure that your customers know that their conversation is with an authentic company — this message cannot be faked by a scammer as it is generated by WhatsApp.
Opt-in
One of the reasons why WhatsApp is successful is its stance against spam behavior. That’s why their opt-in plays a crucial role in WhatsApp Business Account B2C interactions. The opt-in must be an active opt-in; it needs to be triggered by a user action, such as entering a phone number or checking a box to indicate consent.
An end user must first consent to receiving messages from the brand on WhatsApp by opting in via a third-party channel. This can be any channel your business uses to communicate with the customer today — your website, app, email, SMS, retail location, etc. Get inspired here on how to collect opt-ins for WhatsApp
Opt-out
For end user protection WhatsApp has implemented a reporting and blocking mechanism. Enterprises must respect all requests (either on WhatsApp or off) to block, discontinue, or otherwise opt-out of communications from you via WhatsApp. If a user communicates an opt-out selection, enterprises must update their contact list to remove that user and cannot send (or attempt to send) any further messages to that user using the Business Products.
