Change ROAS of PMax Campaign selected via label

[Dominik Fischer]

Hi,

I am working on a solution to change tROAS for several PMax campaigns depending on the current weather on the weekend.

I decides to set up 2 scripts:

1) Fetch weather data, lower tROAS of PMax campaigns & set a label when done -> script is working (runs on Friday)

2) Select PMax Campaigns with the added label and increase ROAS (runs on Sunday)

I can´t get this script to work.

Currently I am sitting on something like this

function main() {

    var campaignName = '(01) PMax | Inventory all | Productgroup Aggressive | CSS: Google';
    var bidAdjustment = 50;
    var namelabel = 'Weather';
 
 
var label = AdsApp.labels().withCondition("LabelNames CONTAINS 'Weather'").get().next();
var Campaigns = label.Campaigns();


while (Campaigns.hasNext()) {
  var Campaigns = Campaigns.next();
        Logger.log("Setting new tROAS because ROAS was reduced during Weekend");
        setCampaignTRoas(campaignName, bidAdjustment);
    }
 
 
}

function setCampaignTRoas(name, bidAdjustment) {
    var campaignIterator = AdsApp.performanceMaxCampaigns()
                                                    .withCondition('label.name = "Weather"')
                                                    .get();

    while(campaignIterator.hasNext()) {
        var campaign = campaignIterator.next();
        const currentTRoas = campaign.bidding().getTargetRoas();
        var newTRoas = currentTRoas + bidAdjustment;
        campaign.bidding().setTargetRoas(newTRoas);
        campaign.removeLabel(namelabel);
             
    }
}

Best regards

the problem is caused by the fact that PMax campaigns require a different kind of iterator; 

Unfortunately, only search and display campaigns are supported in the standard campaign selector.
Google Ads Scripts provides separate methods and classes for accessing Performance Max campaign data.

Here’s how to define Selectors and Iterators for Performance Max campaigns using the latest version:
