Connect Papierkram to Hypamoon

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

Possible

The check

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

Public API docs
Yes. A demo of the OpenAPI documentation is public; the full docs are in the account under Settings, API. Read the docs
A key you create yourself
Yes. The API documentation and your key are in your own account under Einstellungen, API. papierkram.de
Versions or a changelog
No. The API is marked as beta. papierkram.de
How it signs in
An API key that you create in your Papierkram account.
Webhooks
Not confirmed.
Hosting
Cloud
Condition
The API is still in beta and limited to a number of credits per month, depending on the package (M or L).

In practice

What it takes in a real Papierkram administration.

Getting access
Not confirmed; the account shows the API documentation under Settings, API.
Limits
Credits per month: 10,000 on plan M and 20,000 on plan L; each call uses a number of credits. papierkram.de
Writing
Read and write. You can create data in Papierkram, for example documents, at a higher credit cost than reads.
Cost
API credits are included in plans M and L; extra credits through support. papierkram.de

What you can build

Create invoices and contacts in Papierkram from your own order flow, and ask your chat which invoices are overdue.

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.
  • The API can read and, since June 2023, also write data. Because it is in beta, expect changes.

Try it in your chat

First get access from Papierkram. 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.
