Activating Pre-bid for Open Auction buying

Overview: The following information is pertaining to how the IRIS.TV Contextual Video Marketplace activates contextual data partners segments for open auction buying via contextual data partners pre-bid integration in the DSP.

How Contextual Data Partners Utilize the iris_id:

Available contextual data partners can utilize the Context API route to retrieve the source_url for an iris_id. The contextual data provider will be responsible for querying IRIS.TV when they receive an unknown iris_id.

How to Retrieve an iris_id

Contextual data partners have two scenarios when they will want to match a source_url to an iris_id, which include:

Retrieving the source_url for an unknown iris_id: If a data partner receives an unknown iris_id from a DSP they will need to retrieve the source_url for the unknown iris_id.
Retrieving a new iris_id once the current one has expired: If a data partner want to actively retrieve a new iris_id to replace an expired iris_id.

The parameters necessary for both approaches above include:

access_token : created using the OAuth standard. IRIS.TV will provide the data partner with a client ID and client secret.
iris_id : The iris_id sent to the data partner by the DSP.

Context API Route for Retrieval:

The iris_id should be passed as a query parameter. The access_token is passed in the header. Here’s a curl example of the request:

$ curl -D - -H "Authorization: Bearer eyJlbmMiOiJBMjU2Q0JDLUhTNTEyIiwiYWxnIjoiZGlyIn0..QDidXo9Z96KCluZ4kLbtMg.Fw3Wm064Co78iCFWtBL8Hwp-RX7YgtsvsXGizHKv3w0.EJiELVDD14HmqkuvzPfunjIaKS3427GOaFqsvIs8MUc" https://context.iris.tv/refresh?id=iris_55824d003e738991

If the iris_id is valid, IRIS.TV will return a 200 response with the following parameters:

iris_id - the asset’s current iris_id.
iris_id_expires_at - the UNIX timestamp when the current iris_id will expire.
iris_id_next - the iris_id that will be valid after the current one expires.
iris_id_next_expires_at - the UNIX timestamp for when the next iris_id will expire.
source_url - the source_url for the video asset.

Retrieving the source_url For an Unknown iris_id:

When data partners receive an unknown iris_id from a DSP, they will query IRIS.TV with the unknown iris_id. IRIS.TV will respond with the following:

{    "source_url" : "https://www.sample_pub_url.mp4",
     "iris_id" : "iris_78191lilpoe019",
     "iris_id_expires_at" : 1588291200,
     "iris_id_next" : "iris_1897aflaja",
     "iris_id_next_expires_at" : 1588401200
     }

Retrieving a New iris_id When One Has Expired:

Once the TTL for an asset’s iris_id has passed, the data partner will query IRIS.TV with an asset URL to retrieve the new iris_id.

Data Partner should make a call to the IRIS API
IRIS API will respond with the following:

{    "source_url" : "https://www.sample_pub_url.mp4",    
     "iris_id" : "iris_78191lilpoe019",
     "iris_expires" : 2020-04-15 17:55:07.582Z,
    "iris_id_next" : "iris_1897aflaja",
     "iris_id_next_expires_at" : 1588401200
     }

Data partners are responsible for the above workflows and how that operates with their DSP partners in order to have valid iris_ids at all times.
