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. - Only the account owner can create webhooks. Software built for other Follow Up Boss customers must be registered as a system. ## Try it in your chat Fill in what to read and write, and send it.
