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.<ul><li>One API, three channels — the same request format for WhatsApp, Instagram DM and Messenger; no per-channel logic to build and maintain.</li><li>Built for AI agents &amp; chatbots — receive messages on a webhook, process them with your model or agent, send replies through the API. It's a primary use case.</li><li>Verified n8n nodes&nbsp;— build agent visually in n8n, no code; action + trigger nodes (with HMAC verification built in), installable right from n8n.</li><li>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.</li><li>Official Meta APIs — no ban risk — built on the WhatsApp Cloud API, Instagram Messaging API and Messenger API, not browser automation or unofficial clients.</li><li>Ship in an afternoon, not a sprint&nbsp;— a step-by-step cookbook walks you through the whole integration end-to-end, from connecting an account to your first two-way message.</li><li>AI-friendly docs&nbsp;— 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.</li><li>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.</li><li>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.</li></ul>📖 Documentation:&nbsp;<a target="_blank" rel="noopener noreferrer nofollow ugc" class="break-all link-break text-gray-500 hover:underline" href="https://fiwano.com/documentation">https://fiwano.com/documentation</a>📦 Cookbook — step-by-step integration guide:&nbsp;<a target="_blank" rel="noopener noreferrer nofollow ugc" class="break-all link-break text-gray-500 hover:underline" href="https://github.com/fiwano-com/fiwano-cookbook">https://github.com/fiwano-com/fiwano-cookbook</a>🚀 Create an account &amp; API key: 7-day free trial, no credit card
