No per-channel code.\n\n- **Text** \u2192 echoed back.\n- **Anything else** (image, audio, video, document\u2026) \u2192 a reply describing the attachment.\n\n### Before you start\n**Connect at least one channel first** \u2014 use the *Connect a Channel* workflow, or the [Fiwano portal](https://fiwano.com). The responder wires itself to channels you've already connected; with none connected, there's nothing to reply on.\n\n### Setup\n1. Add your **Fiwano API** credential to the Trigger and both reply nodes.\n2. *(Recommended)* Set a **Webhook Secret** on that **credential** \u2014 the Trigger uses it to verify incoming signatures. (The node's own Webhook Secret field is just an override; leave it empty to use the credential's.)\n3. **Save & Activate.**\n\n### What activation does\nThe Trigger is set to **Auto-Setup \u2192 All Active Channels**: on activation it points **every active channel** at this workflow at once \u2014 registering its webhook URL, the selected **Event Types**, and the credential's secret. Connect a channel later? Re-activate to wire it. Deactivating clears the webhook again.\n\nKeep **Event Types** on *Message Received*. n8n must be publicly reachable.\n\n[Docs](https://fiwano.com/documentation/n8n) \u00b7 [Get an API key](https://fiwano.com)",
