The Windows Store submission API was launched earlier this year, enabling you to automate app, IAP durables and consumables, and package flights publishing through a REST API. Using the submission API helps speed up publishing, automate release management and reduce publishing errors.

This month, the submission API added two new capabilities:

If you try the submission API and receive an access denied error, please use the Feedback option at the bottom right of the Dev Center dashboard and select Submission API for the feedback area to request access.

To get started, read the API documentation and samples. You can also use Windows Store analytics API, which retrieves analytics data for all the apps in your account also through a REST API.

Visual Studio to get started.

The Windows team would love to hear your feedback. Please keep the feedback coming using our Windows Developer UserVoice site. If you have a direct bug, please use the Windows Feedback tool built directly into Windows 10.
