Adwords script to pause campaigns when budget is met for the account

Adwords will overspend your account, this script will stop your campaigns when you have reached your daily budget.

function main() {
  
  // GET THE TOTAL SPEND OF THE ACCOUNT
 var costReport = AdWordsApp.report("Select Cost from ACCOUNT_PERFORMANCE_REPORT DURING TODAY");

  var reportRow = costReport.rows().next();
  var totalCost = reportRow["Cost"].replace(',', ''); // Remove thousand separator
  
  // PAUSE THE ACTIVE CAMPAIGNS IF THE BUDGET IS REACHED. REPLACE "XXXX" WITH YOUR BUDGET.
  if (totalCost > 400){
    var campaignIterator = AdWordsApp.campaigns().withCondition("Status = ENABLED").get();

    while (campaignIterator.hasNext()){
      var campaign = campaignIterator.next();
      campaign.pause();
    }
  }
}
