Incoming bid request from SSPs

  • Article

Note

This describes Xandr's integration with the OpenRTB 2.4 protocol.

This Bid Request is sent by SSPs and contains information on which advertisers and creatives are allowed to win an auction. Xandr will produce a Bid Response that contains a bid price and a creative to serve.

Implementation

Endpoints

You will receive one or more endpoints that you can use to POST bid requests. Contact your Xandr representative to receive your endpoints. Endpoints will generally look like the following:

https://seller-region.adnxs.com/openrtb2?member_id=YOUR_MEMBER_ID
  • member_id is required; this is your member ID on the Xandr platform. This ID will be provided by Xandr during integration.
  • You will receive one endpoint for each region in which you operate. Possible regions include: us-east, us-west, emea, and apac.

Any other query string value will be ignored.
