Fiwano is a unified API for integrating WhatsApp, Instagram DM and Facebook Messenger into SaaS products, AI agents, CRMs, helpdesks and automation workflows. Instead of building and maintaining separate Meta integrations, developers can receive inbound messages through unified webhooks and send replies through one REST API. Fiwano handles Meta app setup complexity, token refresh, webhook retry delivery, API version tracking and channel-specific request differences. For B2B SaaS and agency products, Fiwano also supports embedded setup flows. Your product can generate a setup link, send your customer into Facebook authorization, let them select the required Meta channels, and then use Fiwano API to receive and send messages without making the customer log in to Fiwano. Fiwano is built for builders who need official Meta APIs without a heavy CPaaS or inbox platform: - Solo builders and vibe coders building AI agents. - Automation professionals and n8n builders. - Agencies connecting client Meta channels repeatedly. - SaaS teams embedding customer-owned WhatsApp, Instagram or Messenger channels. Plans start at $12/month for text messaging and $19/month for media and WhatsApp templates.
