Starting September 8, 2025, every new line item will need to declare whether or not they will serve Eurpoean Union (EU) political ads. Display & Video 360 API and SDF uploads that don't provide declarations will fail. See our deprecations page for more details on how to update your integration to make this declaration.
Required. The ID of the inventory source group to which these assignments are assigned.
Query parameters
Parameters
pageSize
integer
Requested page size. Must be between 1 and 100. If unspecified will default to 100. Returns error code INVALID_ARGUMENT if an invalid value is specified.
pageToken
string
A token identifying a page of results the server should return.
Typically, this is the value of nextPageToken returned from the previous call to assignedInventorySources.list method. If not specified, the first page of results will be returned.
orderBy
string
Field by which to sort the list. Acceptable values are:
assignedInventorySourceId (default)
The default sorting order is ascending. To specify descending order for a field, a suffix " desc" should be added to the field name. Example: assignedInventorySourceId desc.
filter
string
Allows filtering by assigned inventory source fields.
Supported syntax:
Filter expressions are made up of one or more restrictions.
Restrictions can be combined by the OR logical operator.
A restriction has the form of {field} {operator} {value}.
All fields must use the EQUALS (=) operator.
Supported fields:
assignedInventorySourceId
The length of this field should be no more than 500 characters.
Union parameter accessor. Required. Identifies which DV360 entity the request is being made within. The LIST request will only return assigned inventory sources that are accessible to the DV360 entity identified within the accessor. accessor can be only one of the following:
The ID of the advertiser that has access to the assignment.
If the parent inventory source group is partner-owned, only advertisers to which the parent group is explicitly shared can access the assigned inventory source.
Request body
The request body must be empty.
Response body
Response message for AssignedInventorySourceService.ListAssignedInventorySources.
If successful, the response body contains data with the following structure:
