Telegram Hotel Search Bot (OpenAI + WinWin MCP) | n8n Workflow

Find real hotel offers in Telegram—powered by OpenAI + WinWin MCP (n8n Workflow)

This Telegram Hotel Search Bot workflow lets you search and display live hotel deals inside Telegram. It uses an OpenAI-powered agent with WinWin MCP to find offers, then sends rich offer cards with photos, pricing, dates, a Google Maps link, and booking buttons—plus a built-in photo gallery powered by an n8n Data Table.

What this workflow does

• Triggers on Telegram messages and button taps (callback queries), routing requests by type (start, free-text search, gallery request, or other actions).
• On /start, sends a welcome message; on searches, shows a “searching” acknowledgement.
• Uses an OpenAI agent with Postgres chat memory to interpret the user’s request and call the WinWin MCP search (with filters when needed).
• Validates photo URLs via the Photo Validation tool before sending.
• Parses the agent’s structured output into up to three offers. If no results are returned, sends a “no results” Telegram message with the search summary.
• Formats each offer into a Telegram card including photos, pricing, dates, highlights, Google Maps link, a View Gallery button, and the booking URL.
• Saves all hotel- and room-level photo URLs for displayed offers into an n8n Data Table so galleries can be shown later without re-running the WinWin search.
• When users tap View Gallery, they can choose hotel or room photos; the workflow loads matching rows from the Data Table, validates reachable URLs, and sends photos back in media groups.

Use cases

• Build a Telegram-based hotel deals assistant for SaaS demos or customer support.
• Demo “live search → rich results cards” using n8n, OpenAI, and WinWin MCP.
• Create an interactive experience where users browse photo galleries and book directly via inline buttons.
