Using session variables

If the ADS requires a query parameter named deviceSession to be passed with the unique session identifier, the template ADS URL in AWS Elemental MediaTailor could look like the following:

https://my.ads.server.com/path?deviceSession=[session.id]

AWS Elemental MediaTailor automatically generates a unique identifier for each stream, and enters the identifier in place of session.id. If the identifier is 1234567, the final request that MediaTailor makes to the ADS would look something like this:

https://my.ads.server.com/path?deviceSession=1234567

If the ADS requires several query parameters to be passed, the template ADS URL in AWS Elemental MediaTailor could look like the following:

https://my.ads.server.com/sample?e=[scte.avails_expected]&f=[scte.segment_num]&g=[scte.segments_expected]&h=[scte.sub_segment_num]&j=[scte.sub_segments_expected]&k=[scte.segmentation_type_id]
