Contextual data partners have two scenarios when they will want to match a source_url to an iris_id, which 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:
| Code Block |
|---|
$ 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.
...
Note on “source_url”
There are two important limitations on the “source_url”.
...
If a client’s CDN is using signed URLs, IRIS.TV will only send a stemmed version of the URL that will exclude the dynamically generated token. IRIS.TV will communicate to the data partner both (a) what clients will have stemmed URLs and (b) where the stemming will occur.

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:

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.
