Integrate with a channel manager API for short-term rental listings (Guesty or Hostaway)

Steps

1. Register as a technology partner with the channel manager (Guesty or Hostaway) and obtain API credentials; both use OAuth2 or API key flows documented in their developer portals.
2. Retrieve the list of properties (listings) managed under the account using the listings endpoint; store the channel manager's listing ID for each property.
3. To update availability and pricing, send calendar updates via the calendar or availability endpoint, specifying the listing ID, date range, nightly rate, and availability status.
4. To receive reservations, register a webhook endpoint URL with the channel manager; they will POST reservation events (created, modified, cancelled) to your endpoint.
5. Parse incoming reservation webhooks: extract guest name, check-in/check-out dates, total payout, booking source (Airbnb, Vrbo, direct), and reservation status.
6. Respond to webhooks with HTTP 200 within the timeout window (typically 5–10 seconds); process heavy logic asynchronously via a queue.
