Generate hotel guest upsell recommendations with OpenAI, Sheets and Slack

Description

📘 Description
This workflow automates guest upsell discovery and recommendation for hotels by combining Google Sheets, OpenAI, and Slack. It is designed to help hospitality teams proactively identify the single best upsell opportunity for each guest—before arrival or during the stay—without manual analysis or guesswork.

The workflow runs on a fixed daily schedule and reads guest records from Google Sheets, which acts as the operational source of truth. Guests are automatically categorized based on stay status (upcoming arrivals vs. currently checked in). For each guest, relevant context such as room type, repeat status, spend level, preferences, and special occasions is prepared and passed to an AI engine. The AI deterministically recommends one high-confidence upsell (e.g., room upgrade, airport pickup, spa, dining, or experience), returns a structured JSON response, and explains the reasoning behind the recommendation.

The selected upsell type is written back to the spreadsheet for tracking, and a clear, actionable Slack notification is sent to the team so they can act immediately. Any workflow failure triggers a Slack alert, ensuring reliability and operational visibility.
