title: In Google Adwords, how do you programmatically change a budget?
body: <p>Sadly, there are no examples of this (and I've been digging for some time.)</p>
  
  <p>I would like to be able to programmatically modify a campaign's budget. I can see that BudgetService exists, but I don't know how (or where to go to find out how) to get the id of a budget or the name of a budget.</p>
  
  <p>I surmise that one has to query the campaign for its budget, derive from that the budgetId and then use that in a BudgetService request. Is that the case? If not, what's the go?</p>
