Java sample: app submission with game options and trailers

This article provides Java code examples that demonstrate how to use the Microsoft Store submission API for these tasks:

  • Obtain an Azure AD access token to use with the Microsoft Store submission API.
  • Create an app submission
  • Configure Store listing data for the app submission, including the gaming and trailers advanced listing options.
  • Upload the ZIP file containing the packages, listing images, and trailer files for the app submission.
  • Commit the app submission.

Create an app submission

The CreateAndSubmitSubmissionExample class implements a main program that calls other example methods to use the Microsoft Store submission API to create and commit an app submission that contains game options and a trailer. To adapt this code for your own use:
