How to add device(desktop,mobile,tablet) bid modifiers at campaign level in Ads API Beta

[Christoph Lanz]

Hello,

I am trying to create a mobile and tablet bid modifier at campaign level, using the new Ads API Beta. I used the example "AddAdGroupBidModifier.php" from the examples library and tried to modify it to do the same function at campaign level, but I receive an error message. 

Does anyone know how to solve this? Or is there any further documentation or an example to see how to build the request?

Many thanks in advance,

Christoph

This is part of my code where I define the request: (Full code in the attachment)

        $CampaignBidModifier = new CampaignBidModifier([

            'campaign' => new StringValue(

                ['value' => ResourceNames::forCampaign($customerId, $CampaignId)]

            ),

            'bid_modifier' => new DoubleValue(['value' => $bidModifierValue]),

            'device' => new DeviceInfo(['type' => Device::MOBILE])

        ]);

This is the error that I get:

Fatal error: Uncaught UnexpectedValueException: Invalid message property: device in /www/htdocs/w01745db/api.thegoodtraffic.com/google-ads-php-master/vendor/google/protobuf/src/Google/Protobuf/Internal/Message.php:992 Stack trace: #0 /www/htdocs/w01745db/api.thegoodtraffic.com/google-ads-php-master/vendor/google/protobuf/src/Google/Protobuf/Internal/Message.php(79): Google\Protobuf\Internal\Message->mergeFromArray(Array) #1 /www/htdocs/w01745db/api.thegoodtraffic.com/google-ads-php-master/src/Google/Ads/GoogleAds/V0/Resources/CampaignBidModifier.php(70): Google\Protobuf\Internal\Message->__construct(Array) #2 /www/htdocs/w01745db/api.thegoodtraffic.com/google-ads-php-master/api/management/AddCampaignBidModifier.php(122): Google\Ads\GoogleAds\V0\Resources\CampaignBidModifier->__construct(Array) #3 /www/htdocs/w01745db/api.thegoodtraffic.com/google-ads-php-master/api/management/AddCampaignBidModifier.php(74): Google\Ads\GoogleAds\Management\AddCampaignBidModifier::runExample(Object(Google\Ads\GoogleAds\Lib\GoogleAdsClient), in /www/htdocs/w01745db/api.thegoodtraffic.com/google-ads-php-master/vendor/google/protobuf/src/Google/Protobuf/Internal/Message.php on line 992

Hello Christoph,

The only criteria type you can adjust bid modifiers for using CampaignBidModifierService are CALLS. If you want to adjust device bid modifiers, you will need to use the CampaignCriterionService to adjust the CampaignCriterion.

Hello Anthony,

Many thanks for your reply!

As you suggested I tried to use the CampaignCriterionService, and have the following code. It gives me an error message "Resource_Name_Missing", but I am unsure how to add this parameter. I tried to include it in several ways but was not successful. Maybe you can help me out?

Again, many thanks for your help!

Kind regards,

Christoph

    private static function createDeviceCampaignCriterionOperation(

        $languageId,

        $campaignResourceName

    ) {

        $campaignCriterion = new CampaignCriterion([

            'campaign' => new StringValue(['value' => $campaignResourceName]),

            'device' => new DeviceInfo (['type' => Device::MOBILE]),

'bid_modifier' => new FloatValue(['value' => '2'])

]);

        return new CampaignCriterionOperation(['update' => $campaignCriterion]);

    }

Error Message:

ApiException was thrown with message '{ "message": "Request contains an invalid argument.", "code": 3, "status": "INVALID_ARGUMENT", "details": [ { "@type": 0, "data": "type.googleapis.com\/google.ads.googleads.v0.errors.GoogleAdsFailure" }, { "@type": 0, "data": [ { "errorCode": { "requestError": "RESOURCE_NAME_MISSING" }, "message": "Resource name is missing.", "location": { "fieldPathElements": [ { "fieldName": "operations", "index": "0" }, { "fieldName": "update" }, { "fieldName": "resource_name" } ] } } ] } ] }'.

Hi Christoph,

Please have a look at this example. It shows how to update a keyword which you can use a reference on how to define the resource name.

Hi Anthony,

Awesome, this example helped me to create a working Device Bid Modifier at campaign level. I attach the working code in case someone else finds it useful.

Many thanks for your help and have a nice day!

Kind regards,

Christoph
