Connect Sage 200 to Hypamoon

Possible, with help from Sage 200. The API is documented, but you cannot just create a key: access goes through Sage 200 first.

Possible

The check

Three questions about the API of Sage 200, answered from its own docs.

Public API docs
Yes. Public REST API docs and references for Sage 200 Standard and Professional. Read the docs
A key you create yourself
No. You join the Sage 200 API Developer Programme through an order form and API tier; there is a free Explore tier for development credentials. developer.sage.com
Versions or a changelog
Yes. Versioned docs (latest) and an announcements page. developer.sage.com
How it signs in
OAuth 2.0 with credentials from the Sage 200 Developer Programme; the customer or their partner enables the API for Sage 200 Professional.
Webhooks
Not confirmed.
Hosting
Cloud and self-hosted
Condition
Credentials come through the Sage 200 API Developer Programme order form, with paid tiers beyond development.

In practice

What it takes in a real Sage 200 administration.

Getting access
Join the Sage 200 API Developer Programme via the order form; the customer enables the API and grants user access.
Limits
None published.
Writing
Read and write. Read and modify customers, suppliers, products, sales and purchase orders and nominal accounts.
Cost
Free Explore tier for development; production tiers depend on the number of active API keys. developer.sage.com

What you can build

Read customers, sales orders and stock from Sage 200 and create sales orders from your own order tool.

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

  • Sage 200 signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Sage 200 takes more work: ask your chat to check this first.
  • For Sage 200 Professional the customer or their Sage partner installs and enables the API on the site.

Try it in your chat

First get access from Sage 200. Then fill in what to read and write, and send it.

The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.

Say this in your chat

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.
