      Magnite Streaming: Passing Contextual Data

      This details how to format the iris_context and iris_id KVPs in the Magnite Streaming tag integration.

      SpringServe's Magnite Streaming HB Integration

      If you are using the SpringServe ad server, and are passing IRIS-enabled data via the iris_context and iris_id fields, you will need to update all Demand Tags that integrate your SpringServe account with your Magnite Streaming account.

      To do this:

      1. Navigate to your Demand Tag Settings page
      2. Select the Optional Parameters dropdown in the Bid Parameters section
      3. Select the c4 Optional Parameter
      4. Copy and paste the  {{IRIS_CONTEXT}} macro in the text field next to the Optional Parameters dropdown

      When completed, your Magnite Streaming Demand Tag Settings should look similar to what you see in the below screenshot:

      oRTB Integration


      • IRIS_ID will need to be passed to Magnite streaming via the content.id attribute

      • IRIS_context (contextual values) will need to be passed in the extension field, using any of the available c values (c4 is preferred) 

      Here is an example of those values:

      "app": {
              "id": "xtz2u-vlqjo",
              "name": "ExampleName",
              "bundle": "12345",
              "domain": "",
              "storeurl": "https://channelstore.roku.com/details/123456",
              "publisher": {
                  "id": "1009"
              },
              "content": {
                  "id": "iris_c27740c0ee5b113f",

      "ext": {
              "extra": {
                  "c4": "ic_0755895,ic_4890138,ic_4980180",

      Tag Integration

      The tag integration leverages the custom key-value pair formatting to pass in the iris_context and iris_id to Magnite Streaming.

      The iris_context is passed through the c4 parameter, and the iris_id is passed through the keywords parameter.

      Here is an example of how to pass the iris_context key-value through the c4 parameter using the macro (note that the ad server you use may have a different macro that should be used instead of ):

      &c4={{IRIS_CONTEXT}}

      When an ad request containing an value is made, it will then expand to the corresponding IRIS_CONTEXT values as you can see below:

      &c4=ic_0755895,ic_4890138,ic_4980180

      Here is an example of how to pass the macro (which may vary depending on the ad server you are using) through the video ID parameter :

      &videoId={{IRIS_ID}}

      When an ad request is made that contains the macro it will expand to the corresponding IRIS_ID as you can see below:

      &videoId=iris_c27740c0ee5b113f
