Could anyone explain me how this works or point me in the right direction how this can be achieved?

I am not looking for a compiled program to do it for me. I'd like to know the method to write my own solution.

Thank you.

Okay. So I found these 2.

GET api/v1/players/me/states/FullProfile/binary

POST api/v1/players/me/states/binary?schemaVersion={schemaVersion}&stateName={st ateName}&version={version}

But cant recognize the blob. It looks base64 but something seems fishy with it.

Could anyone help me with this?
