Connect Guesty to Hypamoon
Yes, with one catch. Guesty has an open API that you can use yourself, but it signs in with OAuth only, and that takes more work in a Hypamoon adapter today.
OpenThe check
Three questions about the API of Guesty, answered from its own docs.
- Public API docs
- Yes. Public Open API docs with a quick start. Read the docs
- A key you create yourself
- Yes. An admin creates an API application under Integrations, API & Webhooks and copies the client ID and secret. open-api-docs.guesty.com
- Versions or a changelog
- Yes. Paths under /v1 and a published changelog feed. open-api-docs.guesty.com
- How it signs in
- OAuth 2.0 client credentials; a token lasts 24 hours and at most five tokens per key per day.
- Webhooks
- Yes. It can tell your app when something changes. open-api-docs.guesty.com
- Hosting
- Cloud
What you can build
Look up reservations and guests across your listings from your chat, and send a check in message when a booking comes in.
Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. How adapters work
Good to know
- Guesty signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Guesty takes more work: ask your chat to check this first.
- Up to five OAuth applications per account. Marketplace and channel partners use a separate partner route.

Tool not listed? Ask the chat to check its API.
The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.
Check if [software] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog. Link the pages you used.
Fill in the name of your software. Checking needs no connection to Hypamoon.
