You can increase or decrease your monthly budget at any time. When you want to reduce your budget, the platform will not allow you to reduce your budget to an amount lower than what your campaign has spent. Because the platform isn’t in real time and in some cases can be as much as 48 hours behind, you will not be able to reduce your spend to a level that is too close to your actual spend. Should you need to pause your campaign, you can do this at any time on your Campaign Settings page.
