[docs.propstack.de](https://docs.propstack.de/reference/webhooks) **Hosting**\ Cloud ## What you can build Send new website inquiries into Propstack as contacts, and get a message in your chat when a listing price changes. 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](https://hypamoon.com/docs/adapters) ### 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. - Webhooks for 18 events, such as new clients, property updates and tasks, registered through the API. Each account can have only one API key. ## Try it in your chat Fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for Propstack.

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. Say this in your chat > 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.
