I’m looking for a compact web service that accepts rate data from my own external endpoint, reshapes it to Guesty’s pricing format, and pushes the updates to multiple listings through the official Guesty API. What I need built • A small REST endpoint (or equally light web app) that ingests JSON from my external source. • Logic to authenticate with Guesty (OAuth), map the incoming data to the correct listing IDs, and call the Guesty rate-update endpoints in bulk. • Robust handling of pagination, rate limits, and retries so no update is missed. • A way for me to trigger the process manually or on a schedule—CLI, cron, or lightweight UI are all fine. Delivery expectations • Clean, well-commented code in Python (FastAPI), Node.js, or Go—whatever you work fastest in. • A README covering environment variables, setup, and deployment steps (Docker-ready if possible). • Sample test calls or logs that prove rates changed inside my Guesty account. • A short hand-off session to walk me through the workflow. If you’ve integrated with Guesty before, mention it—familiarity with their quirks will be a big plus.
