When is the third-party impression pixel fired?

For server-side reporting, the publisher player requests an audio stream from the AdsWizz streaming server. The server sends audio content with inserted ads to the player and then sends an impression report to the ad platform. AudioGO logs the impressions and fires third-party tracking pixels for audio ads. For companion display ads, the publisher player requests the correct display creative from the ad platform, and display impression reporting is sent back to the ad platform. Client-side tracking pixels are fired if the banner includes a third-party tracking pixel.
