API Support

I want to submit my game on Kongregate. But I get confused between "publishing program" and "uploading your game"

Hello.
The documentation on Mtx.PurchaseItems says that the items parameter can be an: "Array of item identifier strings, or an array of objects each with a name and data field."

I have a multi-platform game that I want to integrate on Kongregate. I'm using PlayFab as my back-end account system.
The rules state that a Kong game cannot require a game to have third party login, but what about optional logins?
Is it OK if my game logs into Kong by default, but has options to link that account to other services, and options to login to other services (as long as the login triggers a link to the current Kong account)?

I was trying to use Gamemaker Studio (with html export) and I was wondering how to intergrate the Kongregate API in my Gamemaker Studio games.

I uploaded a game which appears to be to big. I am aware of the 800px width limit and stayed within it but am still getting scrollbars. Any idea why? My game is 768x576.

Since there isn't an example in C# can someone tell me how it works and how to unwrap the data?

I have been working on my first game and am getting close to an alpha test, but once I get to a beta test I was hoping to have a broader test of my game than just the people I know. Is it possible to upload Visual Basic games to kongregate?

I upload the game and then once it gets to 100% it goes to this blank web page.
