Update API Version

With the new API major version several endpoints have been removed and replaced by new endpoints.
You need to update the API version by yourself in the Merchant Backend. Follow the following steps:
  1. Go to Settings > Development > Version Management
  2. The status should display "update available".
  3. In the Commands column, click on Edit.



  4. The API major version should already be preselected. Just click on Save.

Note: Once the version has been updated, you cannot undo it. 
If you have several clients in one contracting company, you need to repeat these steps for each client so that every client has the API major version.
