AWS Elemental MediaTailor adds ad response lifecycle hooks for monetization functions

feature

AWS Elemental MediaTailor now supports two new lifecycle hooks for its monetization functions: post ad decision server (ADS) response and pre manifest insertion. These hooks allow customers to define custom logic for ad selection, filtering, and final validation directly within MediaTailor. This enhancement removes the need for a separate middleware tier for advanced ad personalization and reduces impact on viewer playback in case of errors. The new capabilities are generally available in all regions where MediaTailor operates.

  • Post ADS response hook for ad processing and filtering

    The post ADS response hook runs after MediaTailor parses an ADS response and resolves all VAST wrappers. Customers can use it to call secondary ad sources, remove ads that violate content policies, or insert house ads before ads are selected and transcoded.

  • Pre manifest insertion hook for final ad pod validation

    The pre manifest insertion hook executes just before MediaTailor returns the ad pod to the viewer, receiving every newly personalized ad break. This allows for a final check on the ads about to play, enabling actions like inserting a personalized slate if a break cannot be filled.
