Create a line item

A line item bids on impressions and serves creative purchased ads inventory. LineItem resources do this based on set budget, bid strategy, and targeting.

YouTube and Demand Gen line items have child resources called ad groups. Ad groups provide another level of targeting under a single line item budget.

Choose configurations

Before creating a line item, review and decide on these settings:

The LineItem resource also has many optional fields. Some are only used by certain types of line items. Read the reference documentation for more information.

Choose creatives

You need to assign at least one valid, approved creative to line item before it begins serving. The line item type will restrict the kind of creatives you can assign.

Use the creative list function to retrieve existing creatives. If you need to create a new creative for the line item, follow our Assign a creative guide. Assign the creative to the line item using its ID.

How to create a line item

Here's how to create a display line item with the following settings:

A inherited flight and budget.
A partner revenue model of 0.1% of total media cost.
A bid strategy set to maximize spend based on viewable impressions.

Java

// Provide the ID of the parent advertiser.
long advertiserId = advertiser-id

// Provide the ID of the parent insertion order.
long insertionOrderId = insertion-order-id

// Provide the display name of the line item.
String displayName = display-name

// Provide the list of IDs of the creative resources that the line item will
// serve.
List<Long> creativeIds = creative-ids;

// Provide whether the line item will serve EU political ads.
String containsEuPoliticalAds = contains-eu-political-ads

// Create the line item structure.
LineItem lineItem =
    new LineItem()
        .setInsertionOrderId(insertionOrderId)
        .setDisplayName(displayName)
        .setLineItemType("LINE_ITEM_TYPE_DISPLAY_DEFAULT")

    new FrequencyCap().setTimeUnit("TIME_UNIT_DAYS").setTimeUnitCount(1).setMaxImpressions(10);
