Connect MKG to Hypamoon

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

Possible

The check

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

Public API docs
Yes. MKG publishes public knowledge base articles on the API, its calls and its webhooks. Read the docs
A key you create yourself
No. The API is part of the MKG Exchange licence, which has to be in place before you can use it. mkg.eu
Versions or a changelog
Yes. Numbered API versions; the current guides describe API v3. mkg.eu
How it signs in
Sign in with an MKG user name and password to get a session cookie, and send the API key of your API application in the X-CustomerID header on every call; a session ends after about 30 minutes without use.
Webhooks
Yes. It can tell your app when something changes. mkg.eu
Hosting
Cloud and self-hosted
Condition
Needs the MKG Exchange licence.

In practice

What it takes in a real MKG administration.

Getting access
You need the MKG Exchange licence. An administrator then creates an API application in MKG, which gives an API key, and an MKG user with the right read or write rights for the integration.
Limits
None published.
Writing
Read and write. Create and change records with POST and PUT, for example sales orders, relations and quotes, when the user has read and write access.
Cost
Needs the MKG Exchange licence; MKG does not publish the price on its API pages. mkg.eu

Your own order status portal on MKG, for customers who want to know where their order is.

  • Relations, sales orders, production orders, stock and articles, through the MKG API.
  • AI that spots production orders that will miss their delivery date and tells sales.
  • A portal for your customers and an email to the planner when something slips.

Ask your chat

Answers straight from your MKG data, in Claude or another chat with the full Hypamoon connection.

  • Which sales orders are due this week but not finished in production yet?
  • What is the current stock of this article?

When something happens

MKG sends a webhook to your app for some events, and the app asks AI what happens next. For the rest an agent checks every 15 minutes.

  1. When

    A sales order line is created or changed in MKG.

    AI decides

    AI checks the promised delivery date against the production planning.

    Then

    Sales gets an email when a date looks unrealistic.

  2. Every 15 minutes

    New orders from the order form on your own site.

    AI decides

    AI checks the article codes, quantities and customer, and flags anything odd.

    Then

    A sales order is created in MKG after you approve.

    AI proposes, you approve

A screen for your team or customers

An app on your own address, with sign-in, on top of the same MKG data.

  • For your customers

    Customers sign in and see their open orders, expected delivery dates and past orders from MKG.

MKG stays the core: your chat builds the rest on its API, as an adapter plus an app and agents in your Hypamoon project. Reading starts after you click Allow in the portal. Every change an agent or a chat makes in MKG 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.
  • MKG says the API is not available in MKG cloud environments for now. It runs on your own MKG server, at an address like https://server:port/mkg, which has to be reachable over HTTPS from the internet.
  • Access always runs through an MKG user with read or read and write rights set in the authorisation overview; MKG advises a separate user per API application. Webhooks follow the Standard Webhooks specification and are still in beta.

Try it in your chat

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