What you can build
Look up transactions and settlements from your chat, and refund or void payments for approval.
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.
- The Webhooks REST API uses the Login ID and Transaction Key as basic authentication, and you need a Signature Key to verify notifications.
