getCampaignId

  • Retrieves the campaignId, if any, a user's Microsoft Store install is associated with. These are present if the user clicked a "ms-window-store://" or "https://" link that included a "cid" query argument the very first time they installed the app. (This value appears to be cached forever, so subsequent installs will not refresh it.) If a non-empty campaign ID is found it will be assumed to be a properly formatted attribution code and have an additional "msstoresignedin" key appended to it indicate whether or not the user was signed in when they installed the application. This key will either be set to "true" or "false".

    Throw

    NS_ERROR_FAILURE for any other errors
