Campaign Budget Assignment

Assign a budget to a campaign

After you have created a CampaignBudget with CampaignBudgetService or identified an existing one, you need to use its resource_name field value in a subsequent call to CampaignService. Note that you can end up with an orphaned budget (a budget associated with no campaign) when the campaign assignment operation fails but the budget creation operation succeeds. We recommend you either reuse or remove such budgets.

New campaign

For a new campaign, in the CampaignOperation.create, set the campaign_budget field of the Campaign object to a budget resource name, as demonstrated in the code example below.

Java

// Creates the campaign.
Campaign campaign =
    Campaign.newBuilder()
        .setName("Interplanetary Cruise #" + getPrintableDateTime())
        .setAdvertisingChannelType(AdvertisingChannelType.SEARCH)
        // Recommendation: Set the campaign to PAUSED when creating it to prevent
        // the ads from immediately serving. Set to ENABLED once you've added
        // targeting and the ads are ready to serve
        .setStatus(CampaignStatus.PAUSED)
        // Sets the bidding strategy and budget.
        .setManualCpc(ManualCpc.newBuilder().build())
        .setCampaignBudget(budgetResourceName)
        // Adds the networkSettings configured above.
        .setNetworkSettings(networkSettings)
        // Optional: Sets the start & end dates.
        .setStartDate(new DateTime().plusDays(1).toString("yyyyMMdd"))
        .setEndDate(new DateTime().plusDays(30).toString("yyyyMMdd"))
        .build();

C#

// Create the campaign.
Campaign campaign = new Campaign()
{
    Name = "Interplanetary Cruise #" + ExampleUtilities.GetRandomString(),
    AdvertisingChannelType = AdvertisingChannelType.Search,

    // Recommendation: Set the campaign to PAUSED when creating it to prevent
    // the ads from immediately serving. Set to ENABLED once you've added
    // targeting and the ads are ready to serve
    Status = CampaignStatus.Paused,

    // Set the bidding strategy and budget.
    ManualCpc = new ManualCpc(),
    CampaignBudget = budget,

    // Set the campaign network options.
    NetworkSettings = new NetworkSettings
    {
        TargetGoogleSearch = true,
        TargetSearchNetwork = true,
        // Enable Display Expansion on Search campaigns. See
        // https://support.google.com/google-ads/answer/7193800 to learn more.
        TargetContentNetwork = true,
        TargetPartnerSearchNetwork = false
    },

    // Optional: Set the start date.
    StartDate = DateTime.Now.AddDays(1).ToString("yyyyMMdd"),

    // Optional: Set the end date.
    EndDate = DateTime.Now.AddYears(1).ToString("yyyyMMdd"),

Existing campaign

To replace the budget of an existing campaign, in a CampaignOperation.update, set the campaign_budget field of the Campaign object to the resource name of an existing budget (along with any other campaign fields that you might want to set). Note that this will replace the existing budget assigned to the campaign with the one specified by the campaign_budget field, since a campaign can be associated with only one budget at a time.

Warning: The best practice is to update your existing budget. All the spend you had on an existing campaign will be ignored if you create a new campaign budget on an existing campaign. Also, modifying a daily budget within 30 days can lead to overdelivery. For example, say you have a budget set for $10. You spend that $10. Then, you create a new budget for $11 on an existing campaign. That means you could spend around $21. If you follow the best practice and update the budget to $11 on your existing campaign, then your spend would be about $11.

Dissociate a budget from a campaign

A campaign must always be associated with a budget. You can remove a budget from a campaign by changing the budget associated with the campaign, thereby replacing it with another budget. To identify campaigns using a particular budget, continue to the next section.

Retrieve campaigns assigned to a budget

Obtaining the list of campaigns that use the same budget can be helpful in balancing budget utilization. The following GAQL query will return all campaigns for the specified budget ID:

SELECT campaign.id
FROM campaign
WHERE campaign_budget.id = campaign_budget_id
