Thank you for your replay.
I know that you can use the Remove operator to alter campaing status, but it's not quite the same as pausing it. What I want to do is to put the campaign on hold for a limited time period and the reactivate it. By removing it I'm losing all the accumlated data the campaign already gained, and thus need to work with a newly created campaign without it.
I think maybe I'm missing something and not working properly with adwords API, because I figured it will be quite handy to have the ability to pause campaigns,
Thanks again,
