Cant change Campaign Budget

[Michael D]

Hi,

Im trying to change the budget of a campaign. Im setting the amount in money and the budgetId in budget. Butr it doesnt work. Do I forgot something?

            //create Campaign with Status

            Campaign campaign = new Campaign();

            campaign.id = CurrentCampaignId;

            campaign.idSpecified = true;

            var money = new Money();

            money.microAmount = amount;

            money.microAmountSpecified = true;

            var budget = new Budget();

            budget.budgetId = CurrentBudgetId;

            budget.budgetIdSpecified = true;

            campaign.budget = budget;

            campaign.budget.amount = money;  

            

            //Create the Operation

            CampaignOperation operation = new CampaignOperation();

            operation.operand = campaign;

            operation.@operator = Operator.SET;

            operation.operatorSpecified = true;

Thank you very much.

Hi,

To create, modify, and delete budgets, please use the BudgetService. See our budgets guide for more information.

Hi,

Thank you. Is BudgetService also to change MaxCpc in AdGroups and Keywords?

Cheers,

Hi Michael,

Your bids (e.g., max CPC) are set via changes to the BiddingStrategyConfiguration of the campaign, ad group, or ad group criterion.

Please see our bidding guide for more details on bidding and the AdWords API. The UpdateKeyword.vb code example also shows how to update the bid for a given keyword (AdGroupCriterion).
