Setting and managing RTB endpoints

Last updated on October 5, 2018

RTBReal-time bidding, auctioning online inventory within an ad exchange. Buyers bid for the impression based on the value of the user, whereas the seller sets pricing floors and awards the impression to the highest bidder. The auction process takes place in milliseconds, which is why the process is referred to as “real-time.” endpoints are locations in your network that connect to the OpenX Ad Exchange and receive bid requests. You must set at least one endpoint before creating traffic sets.

Setting endpoints

When setting endpoints, use the following best practices to reduce latency:

  • If you plan to bid on traffic from multiple geographical regions, set endpoints in or near those regions. For example, if you want to bid on traffic from Japan, select an endpoint server that is as close as possible to Japan.
  • When you create traffic sets, select OpenX data centers that are geographically near your endpoints.

To set an endpoint:

  1. In the UI, go to your My Account.

  2. Click the Real-time Bid Settings tab.

  3. Enter a unique name to identify the endpoint, such as "Japan" or "Mobile traffic". When creating traffic sets, you will select endpoints by name.

  4. Enter a unique endpoint URL, beginning with the protocol identifier: (http:// or https://).

    An automated test immediately validates that the URL can receive a bid requestWhen OpenX Ad Exchange receives an ad request, it sends a communication containing details about the impression to selected real-time bidders to solicit bids for it. and respond to it. An error message appears if the test fails.

  5. Click Save.
    Endpoints appear in the Summary panel on the right after you create them.

Checking QPS allocation for an endpoint

When you create a traffic set, you select an endpoint and allocate QPSQueries per second, a measurement of bid request traffic volume. Higher QPS corresponds to more bid requests. Demand Partners can set QPS limits for RTB endpoints and traffic sets, depending on endpoint server capacity and how much traffic they want to receive.. Any endpoint connected to one or more traffic sets is displayed with total QPS allocated for that endpoint. View these values to gauge load on endpoint servers.

Properties include buying models, spend cap, targeting criteria, maximum QPS, and routing endpoints., click the value.

You can also click on the name of a traffic set to view all of its settings.

Setting compression for an endpoint

If you have compression enabled, you can set it for any individual endpoint to reduce bandwidth usage. OpenX currently supports GZIP compression.

To set compression:

  1. Hover over an endpoint to display the Compression drop-down list.
  2. Select GZIP from the list.
  3. Click Save.

Deleting an endpoint

Note: You can only delete endpoints that are not assigned to traffic sets.

If an endpoint becomes inactive or it is no longer being used to receive traffic, you can delete it:

  1. Hover over an endpoint to display the Delete icon.
  2. Click the Delete icon.
