Connect Versapay to Hypamoon
Yes. Versapay 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 Versapay, answered from its own docs.
- Public API docs
- Yes. Versapay has a developer site with an API reference. Read the docs
- A key you create yourself
- Yes. Account holders set up and disable API credentials themselves in their account settings, in UAT and production. developers.versapay.com
- Versions or a changelog
- Yes. The API reference is versioned (1.3.x) and Versapay commits to backward compatibility with each release. developers.versapay.com
- How it signs in
- HTTP Basic with an API token and key, or a JWT generated alongside them.
- Webhooks
- Yes. It can tell your app when something changes. developers.versapay.com
- Hosting
- Cloud
- Condition
- Needs a Versapay account; without one, Versapay Support sets up the account and the integration.
What you can build
Push invoices from your own system into Versapay so customers can pay them online, and ask your chat which customers paid this week.
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.
- Versapay has a UAT sandbox with simulated settlements, and webhooks for payment and invoice events.
Try it in your chat
Fill in what to read and write, and send it.

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.
