WhatsApp Tech Docs | Security & Encryption

The WhatsApp Business API provides you with the most complete framework to implement this new channel without compromising your GDPR compliance or security policies.

Secure Conversations with WhatsApp Encryption

The WhatsApp Business API is fully programmable, and tyntec — as an official provider — has taken one  step further to enhance security.  At tyntec privacy, secure data transmission, and encryption have been part of our daily operations for over 15 years — much before GDPR even existed.

Media and messages are only stored for delivery and deleted after 7-30 days respectively tyntec has operated telecommunication services for over 15 years and has to follow strict security and data protection regulations — even before the GDPR ruling
HTTPS connection and multiple layer security options, like VPN or TLS, ensure the message data reaches our platform without being exposed

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.
