Observations

The namespace for freegames/vaulted is d5241c76f178492ea1540fce45616757. It was also the case for previous years.

Offer IDs are stated above.

Item IDs are the same for each one of the freegames/vaulted, namely 8341d7c7e4534db7848cc428aa4cbe5a. This can be seen via the hyperlinks aforementioned.

Postman requests

The following requests can be performed with Python or Postman.
