Chat SDK adds WhatsApp adapter support
By Steven Van ·
The adapter supports reactions and multimedia downloads but not message history, editing, or deletion, under WhatsApp's own restrictions.
Vercel's Chat SDK now supports WhatsApp, joining Slack, Discord, GitHub, Teams, and Telegram as supported platforms. Bots built on the new adapter can send messages and reactions, use auto-chunking, and receive read receipts. It also downloads multi-media content such as images, voice messages, and stickers, and supports shared locations via Google Maps URLs. The adapter builds on a community contribution from @ghellach in PR #102.
Some WhatsApp-specific limits apply: the adapter doesn't support message history, editing, or deletion. Cards render as interactive reply buttons with up to three options, falling back to formatted text, and WhatsApp's 24-hour messaging window means bots can only respond within that period after a user's last message.
