All messages sent using the WhatsApp channel of the Sinch Conversation API are securely encrypted “end to end” so they cannot be tampered with in transit, nor after they arrive on the device. This makes the solution ideal for sending content such as boarding passes, account details and other security sensitive details which today may require the ongoing expense of a custom app to obtain the level of security confidence you require.
Through the use of delivery and read receipts you can also be confident that your content has arrived and use these to drive automatic follow-up.
Refer to the WhatsApp Encryption Overview WhitePaper for more details.
