Connect Square Appointments to Hypamoon
Yes. Square Appointments has a public, versioned API and you create the key yourself, so your chat can write the adapter.
OpenThe check
Three questions about the API of Square Appointments, answered from its own docs.
- Public API docs
- Yes. Read the docs
- A key you create yourself
- Yes. Same personal access token as the rest of the Square API. Creating, changing or cancelling bookings for the seller needs a paid Appointments plan. developer.squareup.com
- Versions or a changelog
- Yes. Date based API versions in the Square-Version header. developer.squareup.com
- How it signs in
- Personal access token of your own Square app as a Bearer token; OAuth for apps used by other sellers.
- Webhooks
- Yes. It can tell your app when something changes. developer.squareup.com
- Hosting
- Cloud
- Condition
- Full read and write access to the seller calendar needs Appointments Plus or Premium. On the free plan an app can only manage the bookings it created itself.
What you can build
Check open slots and book, move or cancel appointments from your chat, and send booking details to your own tools.
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
- Your adapter uses a fixed key: you paste it once in the Hypamoon portal, never in the chat, and it only goes to the API host you allow.
- Bookings are handled by the Square Bookings API, together with the Customers, Team, Locations and Catalog APIs.
Try it in your chat

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.
