Advantages of using the appnexusAst adapter over the appnexus adapter include:

  • Requests all the adUnits at once, which reduces latency on page

  • Supports additional formats (such as Video)

  • Will continue to be upgraded as enhancements are made to Prebid.js for expanding capabilities

As part of the transition to Prebid 1.0, the AppNexus AST adapter will become the standard (and only) AppNexus adapter (and be renamed to “AppNexus”). From a developer’s perspective, the primary change from the legacy adapter is that keywords must be passed using the keywords parameter documented below.

All AppNexus placements included in a single call to requestBids must belong to the same publisher object. If placements from two different publishers are included in the call, the AppNexus bidder may not return any demand for those placements.
Note: This requirement does not apply to adapters that are aliasing the AppNexus adapter.
