WhatsApp is currently the most used messenger across majority of the countries worldwide. It has over 1.6 billion users.
One of WhatsApp main selling points is security. All the messages between Amio and WhatsApp are end-to-end encrypted. The messages that you sent via API are secured via HTTPS.
WhatsApp is currently missing buttons but you can easily emulate them using descriptive icons like 1️⃣, 2️⃣ or 3️⃣. However, it can send and receive rich contact cards, media and locations.
