How we built the Twilio API for WhatsApp

WhatsApp was designed as a pure peer-to-peer messaging network with end-to-end encryption between devices. Rather than hitting a central API, WhatsApp business messaging requires hosting, managing and scaling Docker containers that emulate “devices” on the network. In this talk, we’ll dig into how we built the processes, infrastructure and orchestration necessary to reliably do this at scale. We’ll hear from Deliveroo on how they were able to integrate WhatsApp notifications in just a few weeks and the impact it’s had on their business.
