Prebid Video | Prebid Server Example with JW Player (Hosted)

An example of a pre-roll ad using Prebid Server and JW Player (Hosted).

Important: This example uses a test version of Prebid.js hosted on our CDN that is not recommended for production use. It includes all available adapters. Production implementations should build from source or customize the build using the Download page to make sure only the necessary bidder adapters are included.

Warning: Do not forget to exchange the placementId in the code examples with your own placementId!
