Fiwano puts WhatsApp, Instagram and Facebook Messenger behind one REST API, so you can add two-way messaging to an external product — a chatbot, an AI assistant, a CRM or a helpdesk. The core loop is simple: receive a message via webhook, reply through the API.

• One API, three channels — the same request format for WhatsApp, Instagram DM and Messenger; no per-channel logic to build and maintain.

• Built for AI agents & chatbots — receive messages on a webhook, process them with your model or agent, send replies through the API. It's a primary use case.

• Verified n8n nodes — build agent visually in n8n, no code; action + trigger nodes (with HMAC verification built in), installable right from n8n.

• No Meta app setup — connect accounts through our verified Meta Tech Provider app: no developer portal, no app creation, no App Review on your side.

• Official Meta APIs — no ban risk — built on the WhatsApp Cloud API, Instagram Messaging API and Messenger API, not browser automation or unofficial clients.

• Ship in an afternoon, not a sprint — a step-by-step cookbook walks you through the whole integration end-to-end, from connecting an account to your first two-way message.

• AI-friendly docs — the entire documentation ships as a single LLM-ready file (llms-full.txt, docs + OpenAPI). Drop it into your AI coding assistant and let it scaffold the integration against the real API.

• Embed in your SaaS — an OAuth flow lets your customers connect their own WhatsApp/Instagram/Facebook accounts inside your product; your code never touches their credentials.

• Reply-friendly economics — replying to inbound is free across all three channels (within WhatsApp's 24-hour window); a flat subscription with no per-message markup.
