            <v:developerToken>KntZPmiZOmEfvgX07_sjWQ</v:developerToken>
            <v:userAgent>test</v:userAgent>
            <v:validateOnly>false</v:validateOnly>
            <v:partialFailure>false</v:partialFailure>
        </v:RequestHeader>
    </x:Header>

        <v:mutate>

                <v:operand>
                    <v:campaignId>xxxxxxxx</v:campaignId>
                    <v:isNegative>true</v:isNegative>
                    <v:criterion 
xmlns:ns2="https://adwords.google.com/api/adwords/cm/v201702"; 
xsi:type="ns2:Location">
