Where do I change a Live campaign’s end date, budget and CPC?

Within the Manage tab of self-serve, you can change details of your live campaigns. If you select the ‘Edit Campaign’ button, then you can amend the end date, total budget, add/remove a cap, or adjust your CPC.

Any time you make an adjustment to your campaign you will need to “Save & submit for approval” again, if you “Save” your campaign it will be paused.
