Promoting an app in the Ubuntu Software Center through a ratings and reviews API
Ubuntu Software Center can be launched with a package name:
software-center chromium-browser
which displays the 'Write your own review' action, but you usually have to scroll to see it.
If you'd like to be able to display your own review form and submit via the ratings and reviews API, you can do so with the submit_review
API call, but it'll require an authenticated API call... see "Making authenticated API calls" at:
