Connect Ultimo to Hypamoon
Possible, with help from Ultimo. There is an API, but the docs or the key only come after you ask Ultimo for access.
PossibleThe check
Three questions about the API of Ultimo, answered from its own docs.
- Public API docs
- No. The API documentation sits behind the Ultimo customer sign-in; Ultimo only says publicly that it offers a REST API for integrations. Read the docs
- A key you create yourself
- Yes. An Ultimo administrator generates an API key in the Ultimo Configuration Tool; this is described by an integration partner, not on a public Ultimo page. support.workspace365.net
- Versions or a changelog
- Not confirmed. Versioning not visible without the customer documentation.
- How it signs in
- An API key that an administrator creates in the Ultimo Configuration Tool, sent in an ApiKey header.
- Webhooks
- Not confirmed.
- Hosting
- Cloud and self-hosted
- Condition
- The API documentation is only available to Ultimo customers, and the Business Integration REST API is part of the higher Ultimo editions. Integration partners in the Ultimo marketplace (for example Workspace365) connect through the same API.
What you can build
Create work orders in Ultimo from a fault form or chat, and send your team a daily overview of overdue maintenance.
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.
- Ultimo runs mostly as a cloud service; an on premises version is still maintained. An on premises installation would have to be reachable over HTTPS for any adapter.
- Ultimo works with certified partner integrations. Ask Ultimo or your administrator which API your environment offers before you plan an adapter.
Try it in your chat
First get access from Ultimo. Then fill in what to read and write, and send it.

In Claude, or another chat with the full Hypamoon connection; adapters are not in ChatGPT yet. You paste the key in the portal, never in the chat. The full recipe

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.
