Connect Nmbrs to Hypamoon
Yes. Nmbrs 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 Nmbrs, answered from its own docs.
- Public API docs
- Yes. Read the docs
- A key you create yourself
- Yes. A Starter subscription on the developer portal gives a client ID and secret at once. Private and partner subscriptions need validation by Nmbrs first. developer.payroll.nmbrs.com
- Versions or a changelog
- Yes. Versioned API with update notes; the older SOAP API ends on March 1, 2027. support.nmbrs.com
- How it signs in
- REST API with OAuth 2.0 via the developer portal. The older SOAP API uses your username and an API token, but it stops on March 1, 2027.
- Webhooks
- Yes. It can tell your app when something changes. support.nmbrs.com
- Hosting
- Cloud
What you can build
Look up employees, payroll runs and wage tax declarations from your chat.
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.
- Webhooks are set at debtor level for events such as a finished payroll run. Build on the REST API, since the SOAP API is being retired.

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.
