OpenWrap CTV Video API Specification
OpenWrap supports CTV inventory using GET/POST methods. OpenWrap accepts BidRequest in OpenRTB 2.5 format for POST API, and the same specification for GET API, but using only key/value pairs.
POST API
OpenWrap supports CTV inventory as defined in the Object: Video section of the IAB OpenRTB API Specification Version 2.5, with some minor differences. For example, PubMatic's CTV BidRequest implementation supports multiple video impressions. The following sample shows how a typical impression might appear using the /video/vast endpoint.
The CTV Video API supports three endpoints:
/video/openrtb/video/vast/video/json
Learn more at, CTV endpoints.
The next section provides example JSON payloads that illustrate unsupported features of OpenRTB 2.5.
POST API limitations
OpenWrap's HTTP POST method ignores banner, native, and audio objects.
Unsupported examples
The table below lists JSON payload snippets that illustrate OpenRTB 2.5 structures that OpenWrap does not support at this time.
| Object | Description |
|---|---|
BidRequest.Imp.Banner | Full banner object unsupported. OpenWrap ignores the impression object if it contains a banner object. OpenWrap removes a banner object from an impression when it is specified with a video object in the same impression. |
BidRequest.Imp.Audio | OpenWrap ignores impression object if it contains an unsupported audio object. OpenWrap removes an audio object from an impression if it is specified with video object in the same impression. |
BidRequest.Imp.Native | Full native object not supported. OpenWrap ignores impressions when they contain a native object. OpenWrap removes the native object from the impression if it is specified with a video object in the same impression. |
GET API parameters
Using HTTP GET, you'll send all BidRequest parameters and values encoded in the URL. The sections below show the Required parameters, followed by the Optional parameters, and a brief example for each.

The following table lists the parameters available to let you configure User objects.
| Parameter | Type | Description | Example |

Dynamic Extension object
We can add any number of extension parameters dynamically by providing nested objects separated by dot, resulting in a String Parameter.
To learn about supporting other data types in the Ext object…
Contact the PubMatic OpenWrap Team.
Passing sample ext parameter such as, req.ext.ow.bidder.name=pubmatic
and
req.ext.ow.pubmatic.consent=present:
Dynamic Extension Parameter Example
{
"ext": {
"ow": {
"bidder": {
"name":"pubmatic"
},
"pubmatic" : {
"consent":"present"
}
}
}
}

GET API limitations
GETAPIsupports single video impression only. It currently does not support multiple impressions.- Use standard URL encoding for all String parameters to ensure requested URL doesn't break.
- The default format for all String Array parameters is comma separated.
- The dynamic extension parameters currently support only JSON string and JSON object data types. No other JSON data types are supported at this time.
AdPod object
AdPod is an Extension object of the
BidRequest or
Impression.Video objects described above.
Info
For more information, see Ad Pod Support for OpenWrap Video.
You reference AdPod objects using the Extension object hierarchy, and the table below shows the object path to use for the HTTP GET and POST methods.
GET API | POST API | Scope notes |

req.ext.adpod.[param] | bidrequest.ext.adpod.[param] | BidRequest parameters are global in scope, including default values. |
imp.vid.ext.adpod.[param] | video.ext.adpod.[param] | Impression.Video object parameters override global scope parameters from BidRequest. |
The following table lists the parameters available to let you configure AdPod objects.
| Parameter | Type | Mandatory (with a defined AdPod object)? | Description | Default value (with a defined AdPod object) |
|---|---|---|---|---|
offset | Integer | | Defines the position where the AdPod might play in a long video; for example, 30 min from start. This helps define duration based rules to determine when the same ads can/cannot play. | 0 |

CTV endpoints
| Endpoint | Description |
|---|---|
OpenRTB endpoint returns IAB Standard OpenRTB 2.5 formatted response for a | |
VAST endpoint returns VAST-format XML response for a video | |
/video/json
| This CTV video endpoint will cache individual AdPod creatives and return targeting values in response. Learn more. |
OpenRTB endpoint response
IAB Standard Open RTB 2.5 BidResponse format.
VAST endpoint response
The VAST endpoint returns a standard VAST XML response. In the cases of, Request ERROR, Application ERROR, or No Bid, the endpoint returns an empty VAST tag with error details in the response headers. Supported VAST versions: VAST 2.0, VAST 3.0.
JSON endpoint response
The JSON endpoint will cache all individual creatives of adpod and returns the targeting keys of that creatives.
CTV endpoint assumptions
- Currently, OpenWrap server-side works only in USD currency. OpenWrap currently automatically replaces any other currency with USD. Note that ECPM values are also reported in USD.
- Server Side Auction is done for all CTV requests whether or not the
req.ext.wrapper.ssauctionparameter is defined. - Creative Blocked Attributes, Blocked Domains, Blocked Categories, and Allowlisted Categories are not yet implemented by OpenWrap CTV video. OpenWrap will forward the request to partners via prebid and it is the partner's sole responsibility to serve creatives based on these attributes.
- Profile level platform is not checked for CTV endpoints, which means Display/InApp other profiles are served for video request.
- Profile ID is mandatory for CTV requests using both
GETandPOSTmethods.
