The API-Request returning your stock as a file can now also return a file with all sealed product. Please refer to the respective documentation: Stock (File).

API available under Cardmarket.com

January 22nd, 2018

The API is now also available under the Cardmarket.com domain structure. Please make sure to change over your implementation from www.mkmapi.eu to the new api.cardmarket.com domain until August 1st, 2018. We will switch off the old domain on that day as well as the API version 1.0.

The sandbox server will return under cardmarket.com during February 2018.


To effectively help with any problems regarding API requests, we need the following information - as complete as possible and independent from any used programming language, libraries, frameworks, etc.:

We also don't need any implementation steps like base string composition or signature calculation steps, "naked" request information is everything we need.
