Third-party serving
Advertisers can use third-party video tags from an Amazon certified third-party vendor. The tags must be Inline VAST 2.0 or VAST 3.0, and may include VPAID 2. We do not accept VPAID or Wrapper Tags.
Please note only VAST 3.0 is supported for Twitch. OLV packages will not deliver on Twitch if creative is submitted without VAST 3.0 tags.
Viewability
Video viewability should be measured using VPAID tags from one of the approved vendors.
CORS header formatting
In order for JavaScript video players to accept a VAST response, ad servers have to include a Cross Origin Resource Sharing (CORS) header formatted as:
Access-Control-Allow-Origin: <origin header value>
Access-Control-Allow-Credentials: true
Without a valid VAST response, a video creative will not serve on Amazon-owned sites. This ensures a positive experience for Amazon’s customers.
