I am currently working on a plugin which requires the inventory of the player who is using the plugin. I am using the inventory API and a public proxy server to achieve this, however, the difficulty I am having is that I am not granted access to my own inventory since it is set to private. I did come across the authorization API but I am not sure how to use it and if it is the solution towards this problem.
You could access your own inventory if you are in your account while looking at the API and your inventory is public. If you are going to use a proxy route for the API you cannot.
