AGNT v0.2 — WhatsApp bridge via 360Dialog

WhatsApp is the dominant messaging platform in Bali and across Southeast Asia, so bringing Andy to WhatsApp was the highest-priority feature after MVP launch. AGNT v0.2 integrates the 360Dialog Cloud API for inbound webhook processing, outbound template messages, and media uploads. Users verify their WhatsApp number with a 6-digit OTP (5-minute expiry) and immediately start chatting with Andy.

The session store was refactored to be channel-agnostic. A user who starts a venue search on Telegram can continue the conversation on WhatsApp without losing context. Message routing detects the inbound channel and formats responses appropriately — WhatsApp gets rich media cards while Telegram uses inline keyboards. Language detection runs on every inbound message so Andy responds in the user's preferred language without manual configuration.

On the infrastructure side, the send queue gained per-channel retry logic with exponential backoff and dead-letter handling. WhatsApp template messages require pre-approval, so a template registry was added to the venue admin dashboard where operators can manage and preview their approved templates before deployment.
