Asynchronous API

Business logic often requires a need to execute asynchronous code that requires knowledge of the next playlist item before either making an adjustment to that playlist item, or preventing its playback altogether. We've extended the API to allow for asynchronous blocking between playlist items. Loading, ads, and playback of the next playlist item can be blocked until async operation resolves.


Release Date: June 8, 2020 (Build 106)


  • Added API to enable developers to modify a playlist item, prevent it from loading and transition instead to the following item, modify the ad block, and disable ads.
  • Service improvements to increase stability.


  • Fixed an issue where the mute API did not affect Freewheel ads.
