Introduction

Publishers can use Prebid Server in any of the following ways with Index Exchange (Index). Index’s adapter supports all of the following methods:

• If you want to call Index from a web environment, you can use Prebid.js to call Prebid Server, and then Prebid Server uses our server-side adapter to call Index. This reduces workload on the browser. For set up instructions, see Call Index from a web browser section on this page.
• In mobile apps, you can use the Prebid Mobile SDK to call Prebid Server and then Prebid Server uses our server-side adapter to call Index. For set up instructions, see Call Index from Prebid Mobile SDK section on this page.
• In CTV apps and other long-form video environments, you (or the SSAI vendor) can make a call to Prebid Server using OpenRTB, and then Prebid Server uses our server-side adapter to call Index. For set up instructions, see Call Index from CTV/long-form video environment section on this page.
• In any other server-to-server OpenRTB environment, you can send OpenRTB bid requests to the Prebid Server host of your choice. For set up instructions, see Call Index from any other server-to-server OpenRTB environment section on this page.

Note about sending multiple ad slots in a single bid request: Index accepts up to 100 valid ad slots in a single bid request. If a single bid request contains more than 100 ad slots (including invalid ad slots), only the first 100 valid ad slots are accepted and the rest are ignored. For example, streaming TV media owners can signal multiple ad pods for long-form programming in a single request.

Supported media types

The following table lists the media types that Index supports. For information about the the Time-To-Live (TTL) for each media type, see How Index counts impressions in our Knowledge Base.

Configure the Index adapter in your Prebid Server instance

Before you begin: Contact your Index Exchange Representative to get an endpoint and setup instructions.

If you are hosting your own Prebid Server instance, depending on whether you are using Prebid Server Go or Prebid Server Java version, complete one of the following steps:

• If you are using the Prebid Server Go version, in the static/bidder-info/ix.yaml file, complete the following:

  • Enable the adapter by deleting the disabled: true entry.

  • Add the following new entry and include the regional endpoint provided to you by Index:

     endpoint: "https://<ENDPOINT URL>"
    

  • Edit the below existing entry and include your publisher ID in the s parameter:

     userSync:  
      redirect:  
       url: "https://ssum.casalemedia.com/usermatchredir?s=<PUBLISHER ID>&gdpr={{.GDPR}}&gdpr_consent={{.GDPRConsent}}&us_privacy={{.USPrivacy}}&cb={{.RedirectURL}}"
    

  • Edit the below existing entry and include your publisher ID in the s parameter:

     userSync:  
      redirect:  
       iframe: "https://ssum.casalemedia.com/usermatch?s=<PUBLISHER ID>&gdpr={{.GDPR}}&gdpr_consent={{.GDPRConsent}}&us_privacy={{.USPrivacy}}&cb={{.RedirectURL}}"
    

• If you are using Prebid Server Java version, edit the prebid-server-java entry in the src/main/resources/bidder-config/ix.yaml file as follows:

  • Edit the below existing entry and include the endpoint URL provided to you by Index.

    adapters: 
     ix: 
       endpoint: "https://<ENDPOINT URL>"
    

  • Edit the below existing entry and include your publisher ID in the s parameter:

     adapters: 
       ix: 
        usersync: 
         redirect: 
          url: "https://ssum.casalemedia.com/usermatchredir?s=<PUBLISHER ID>&gdpr={{.GDPR}}&gdpr_consent={{.GDPRConsent}}&us_privacy={{.USPrivacy}}&cb={{.RedirectURL}}" 
    

  • Add the below entry and include your publisher ID in the s parameter:

    adapters: 
      ix: 
       usersync: 
        iframe: 
         url: "https://ssum.casalemedia.com/usermatch?s=<PUBLISHER ID>&gdpr={{.GDPR}}&gdpr_consent={{.GDPRConsent}}&us_privacy={{.USPrivacy}}&cb={{.RedirectURL}}"
    

Publisher instructions to call Index through Prebid Server

If you are using an existing Prebid Server instance that is already configured to call Index, depending on whether you want to call Index from the browser, mobile app, CTV, or long-form video, follow any of the below sections to complete the Index-specific configuration.

Call Index from a web browser

To call Index from a web browser using Prebid Server, you must first configure Prebid.js to call Index directly from the browser using our client-side adapter. Follow the quick start instructions provided in Prebid’s Getting Started for Developers documentation. Complete the following steps to complete the Index-specific configuration:

1. Build the binary in one of the following ways:
   • Download Prebid.js from the Prebid site to use the standard compiled binary that Prebid includes in the download process and select Index Exchange as an adapter.
   • Build it on your own from the source code by following the instructions in Prebid.js project README. If you use this method, you will need to include several modules in your build process. See the Index modules to include in your build process section in our Prebid.js documentation on the Prebid site.

2. Define the Index-specific parameters at the bidder level which include adding ix as the bidder and the siteId. For Index’s bidder-specific parameters, see the Bid request parameters section below.

    {
        bidder: 'ix',
        params: {
            siteId: '9999990'
        }
    }
   

3. Define your ad units in the adUnit object. This includes the details about the ad slots such as the media types, ad size, and ad code. For more information about this object, see Prebid’s Ad Unit Reference documentation.

4. Enable user syncing by adding the following code in the pbjs.setConfig() function. Index strongly recommends enabling user syncing through iFrames, though we do also support image-based syncing. This functionality improves DSP user match rates and increases the Index bid rate and bid price. Make sure to call pbjs.setConfig() only once. This configuration is optional in Prebid, but required by Index.

    pbjs.setConfig({
        userSync: {
            iframeEnabled: true,
            filterSettings: {
                iframe: {
                    bidders: ['ix'],
                    filter: 'include'
                }
            }
        }
    });
   

5. (Optional) Set up First Party Data (FPD). For more information about the data types we support and the instructions for each option, see the Set up First Party Data (FPD) section in our Prebid.js documentation on the Prebid site.

6. (Optional) If you want to monetize instream video, you need to enable a cache endpoint in the pbjs.setConfig() function as follows:
   

    pbjs.setConfig({
        cache: {
            url: 'https://prebid.adnxs.com/pbc/v1/cache'
        }
    });
   

7. (Optional) If you want to monetize outstream video, you can choose among the following options:
   • Use Index’s outstream video player. For more information, see the Index’s outstream video player section in our Prebid.js documentation on the Prebid site.
   • Use your own outstream video player. For more information, see Prebid’s documentation on how to show video ads.
8. (Optional) Configure Prebid Native with Index. For more information, see the Prebid Native section in our Prebid.js documentation on the Prebid site. Prebid Native is available from Prebid.js version 7.4.0 or higher.

Call Index from Prebid Mobile SDK

Before you begin: Contact your Index Exchange representative to get your siteId. You must provide this site ID to your Prebid Server host company.

Note: To implement Prebid Mobile SDK, follow Prebid’s Getting Started with Prebid Mobile documentation.

To add Index as a bidder to your mobile app:

1. Inform your Prebid Server hosting company to add ixas a bidder in the configuration and include the siteId that Index provides to you at the time of integration.
2. Define the Index-specific parameters at the bidder level. For information about these parameters, see the Bid request parameters section below.
3. Include any ad unit level required or optional parameters provided in Prebid’s Prebid Mobile API - iOS and Prebid Mobile API - Android documentation.

Call Index from CTV/long-form video environment

Before you begin: Contact your Index Exchange Representative to get the siteId. You must provide this site ID to your Prebid Server host company.

Note: To implement CTV and long-form video using Prebid Server, follow Prebid’s Long Form Video documentation.

To add Index as a bidder:

1. Inform your Prebid Server hosting company to add ixas a bidder in the configuration and include the siteId that Index provides to you at the time of integration.
2. Define the Index-specific parameters at the bidder level. For information about these parameters, see the Bid request parameters section below.
3. Include any ad unit level required or optional parameters provided in Prebid’s /openrtb2/video documentation.

Call Index from any other server-to-server OpenRTB environment

To request bids from Index:

• In requests that you make to your Prebid Server host, add imp.ext.ix and include the siteId that Index provides to you at the time of integration.
  

Example:

    "imp": [{
           "ext": {
              "ix": {
                "siteId": "9999990"
              }
        }
      }],

Bid request parameters

For a list of the OpenRTB fields that Index supports in bid requests, see List of supported OpenRTB bid request fields for sellers. The following are the required fields for the various supported media types.

Banner

You must include these parameters at the bidder level.

Video

You must include these parameters at the bidder level.

If you are using Index’s outstream ad unit and have placed the video object at the bidder level, you must include the Index required parameters at the bidder level. You can include the optional parameters to specify the outstream ad unit configurations.
