A key you create yourself

How it signs in

In practice

What it takes in a real Collmex administration.

Getting access
Create a user with the API only flag in Collmex and post CSV to https://www.collmex.de/c.cmx?<customer number>,0,data_exchange.
Limits
Notifications are sent at most once per minute and stop after 100 unacknowledged ones. collmex.de
Writing
Read and write. Data imports for invoices, orders, payment confirmations and more, plus actions such as a billing run.
Cost
API only users are not charged. collmex.de

What you can build

Push orders and invoices from your own shop into Collmex, and ask your chat for open items per customer.

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.
  • Data goes in and out as CSV over HTTPS POST to an address with your customer number. Notifications call your URL when something changes; you then fetch the changes yourself.

Try it in your chat

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

Say this in your chat

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.
