ChatRail

What is ChatRail?

ChatRail helps developers send, receive, schedule, and auto-reply on WhatsApp through one REST API. It uses linked devices instead of the official Meta Business flow, so you can pair a number by QR, start quickly, and skip template approval. The product includes a workspace for connections, message logs, delivery tracking, retries, scheduling, and session monitoring. You can attach context to each message so AI replies stay grounded in your data, and you can control whether replies are human-reviewed or automated. It also supports webhooks, media, groups, sandbox testing, and MCP tools for managing everything from your editor. The focus is on production alerts, operational workflows, and simple integrations with existing stacks like n8n, Zapier, Supabase, and more.
