Supplying any of the following targeting parameters is optional.
When you create or configure a content source for video on demand (VOD) or set up a live stream for DAI, you need to specify a default video ad tag. All DAI streams use that ad tag and its parameters by default. Ad tag parameters apply to both mid-rolls and pre-rolls. If you want your player to request something unique for a given stream, these options are available to you.
Ad Manager ad tag parameters that can be overridden

Override the default ad tag
When your video player requests a stream, the default ad tag is used exactly as you have specified it in the interface. However, you have the ability to override certain parameters of that tag in your stream request. These are the only parameters that can be overridden.
Learn how to override the default ad tag using the IMA SDK or using SSB.
Parameter | Description | Example value | |
---|---|---|---|
iu |
Current ad unit. This should follow the format: |
iu=/6062/video/example_unit |
|
cust_params |
Key-value pairs that should be used for Ad Manager campaign targeting. Some platforms require URL encoding. The URL encoding requirement does not apply when using the IMA DAI SDK for HTML5, as the value is automatically encoded. This parameter will not work if it is already encoded on HTML5. |
Examples with multiple key-value pairs, such as:
SSB streams: Encode and concatenate the entire
Chromecast:
Roku: Encode and concatenate the entire
iOS, and tvOS: Do not encode anything.
Android: Do not encode anything.

The value should describe the video playing on the page. Usually, it's the page that houses the video player, but could also be a page with text that describes the video. This parameter is not set automatically by the IMA SDK. It needs to be set manually. |

Override the default ad tag using the IMA SDK
When a video player requests a DAI stream using the IMA SDK, it can pass in a field called "adTagParameters
". This dictionary-like structure can be set with key-value pairs where the keys may be the Ad Manager ad tag parameters listed in the table above.
You can customize your stream and pass in parameters which are not related to the Ad Manager ad request using this same structure. Learn how to request specific stream variants and how to set up an ad holiday.
The implementation of the adTagParameters
field is slightly different depending on the specific programming language or platform. See the iOS, Android, tvOS, Chromecast, HTML5 development documentation or additional documentation in the DAI player and app development guide.
Set adTagParameters through the SDK
When you set cust_params
or description_url
through the SDK, on iOS, tvOS, and Android apps, you should not url-encode the strings. You can pass the cust_params
through as a single string that concatenates the key-value pairs with a "&
".
For example, if you wanted to set cust_params
to the value of sport=football&city=newyork
:
The adTagParams
structure using non-encoded values would be:
{
"tfcd": 1,
"iu": "/987654321/path/to/adunit",
"cust_params": "sport=football&city=newyork",
"description_url": "http://sample.com/golf.html",
"ppid": "12JD92JD8078S8J29SDOAKC0EF230337"
}
The adTagParameters
structure using encoded values for HTML5 stream requests would be:
{
"tfcd": 1,
"iu": "/987654321/path/to/adunit",
"cust_params": "sport%3Dfootball%26city%3Dnewyork",
"description_url": "http%3A%2F%2Fsample.com%2Fgolf.html",
"ppid": "12JD92JD8078S8J29SDOAKC0EF230337"
}
The adTagParams
structure using encoded values for Roku stream requests would be:
request.adTagParams="tfcd=1&iu=/987654321/path/to/adunit&cust_params=sport%3Dfootball%26city%3Dnewyork&description_url=http%3A%2F%2Fsample.com%2Fgolf.html&ppid=12JD92JD8078S8J29SDOAKC0EF230337"
Override the default ad tag using the DAI API (Beta)
When a video player requests a DAI stream using the DAI API, it can optionally pass key-value pairs, where the keys may be the Ad Manager ad tag parameters listed in the table above.
These parameters should be sent as part of the HTTP POST request body, of form type application/x‑www‑form‑urlencoded
for both linear/live and VOD.
You can customize your stream and pass in parameters which are not related to the Ad Manager ad request using this same structure. Learn how to request specific stream variant parameters, and HMAC authentication.
See a DAI API sample implementation.
Override the default ad tag using SSB
The following are examples of modifying an SSB default VOD ad tag. Overwritten parameters passed by the player or app are highlighted.
Video on demand examples |
Example | |
---|---|
Base VOD stream URL | http://dai.google.com/ondemand/hls/content/ |
(with an ad unit specified) | http://dai.google.com/ondemand/hls/content/ |
(with overridden key-values) |
http://dai.google.com/ondemand/hls/content/ |
(with a declaration of child-directed content) |
http://dai.google.com/ondemand/hls/content/ |
(with an over-ridden ad unit AND key-values AND a custom description_url AND a declaration of child-directed content) |
http://dai.google.com/ondemand/hls/content/ |
Live linear stream examples |

---|---|
Base live linear stream URL | https://dai.google.com/linear/hls/event/<asset_key> |

(with over-ridden key-values) | https://dai.google.com/linear/hls/event/<asset_key> |

(with an overridden ad unit AND key-values AND a custom description_url AND a declaration of child-directed content) |

Dynamically update targeting parameters during a specific live stream
You can dynamically update the targeting data for a specific user in the middle of watching the stream using the replaceAdTagParameters method in the IMA DAI SDK.
