How can i change existing campaign budget?

[ma...@sumer.me]

Hi,

I am using Ads API v10 with PHP. And i can't update campaign budget with update sample.

Do I always have to create a new budget and add it to that campaign to update the budget? Like this:

$budget = new CampaignBudget([
            'name' => $budgetId.time(),
            'amount_micros' => $amount
        ]);

        $campaignBudgetOperation = new CampaignBudgetOperation();
        $campaignBudgetOperation->setCreate($budget);

        $campaignBudgetServiceClient = $googleAdsClient->getCampaignBudgetServiceClient();
        $response = $campaignBudgetServiceClient->mutateCampaignBudgets(
            $customerId,
            [$campaignBudgetOperation]
        );
       
        $addedBudget = $response->getResults()[0];
       
        $budgetResourceName = $addedBudget->getResourceName();
       
        $campaign = new Campaign([
            'resource_name' => ResourceNames::forCampaign($customerId, $campaignId),
            'campaign_budget' => $budgetResourceName
        ]);
       
        $campaignOperation = new CampaignOperation();
        $campaignOperation->setUpdate($campaign);
        $campaignOperation->setUpdateMask(FieldMasks::allSetFieldsOf($campaign));
       
        $campaignServiceClient = $googleAdsClient->getCampaignServiceClient();
        $response = $campaignServiceClient->mutateCampaigns(
            $customerId,
            [$campaignOperation]
        );

        $updatedCampaign = $response->getResults()[0];

Is there no way to update the existing budget with the budget id?

Hi Mahir,

Thank you for raising this concern to the Google Ads API team.

Moving forward to your concern, it seems that you want to update the existing budget with the budget id. That said, you can use this CampaignBudgetService which allows you to manage your campaign budgets with available operations [create,update,remove]. Unfortunately, the said service is utilizing the resource name of the campaign budget instead of the campaign budget ID.

this is my working code sample.

you need  budgetResourceName or budgetId of existing budget to update campaign budget.

($budget_resource_name=ResourceNames::forCampaignBudget($cam_infos['customer_id'], $budgetId);)

.......

$budgetResourceName = self::updateCampaignBudget($googleAdsClient, $cam_infos['customer_id'], $cam_infos['campaign_budget'],$cam_infos['budget_resource_name']);

........

private static function updateCampaignBudget(GoogleAdsClient $googleAdsClient, int $customerId,int $campaign_budget,string $budget_resource_name){
        // Creates a campaign budget.
        $budget = new CampaignBudget([
            'resource_name' => $budget_resource_name,
            //'delivery_method' => BudgetDeliveryMethod::STANDARD,
            'amount_micros' => $campaign_budget
            //'explicitly_shared' => false
        ]);

        // Creates a campaign budget operation.
        $campaignBudgetOperation = new CampaignBudgetOperation();
        $campaignBudgetOperation->setUpdate($budget);
        $campaignBudgetOperation->setUpdateMask(FieldMasks::allSetFieldsOf($budget));
        // Issues a mutate request.

        $campaignBudgetServiceClient = $googleAdsClient->getCampaignBudgetServiceClient();
        $response = $campaignBudgetServiceClient->mutateCampaignBudgets(
            $customerId,
            [$campaignBudgetOperation]
        );

        /** @var CampaignBudget $addedBudget */
        $updatedBudget = $response->getResults()[0];
        //printf("Added budget named '%s'%s", $addedBudget->getResourceName(), PHP_EOL);

        return $updatedBudget->getResourceName();
