adDecisionServerUrl property
The URL for the ad decision server (ADS) for pre-roll ads. This includes the specification of static parameters and placeholders for dynamic parameters. AWS Elemental MediaTailor substitutes player-specific and session-specific parameters as needed when calling the ADS. Alternately, for testing, you can provide a static VAST URL. The maximum length is 25,000 characters.
