Our tool enables you to create and manage ads on Facebook. However you will need to have funding in your Facebook Ad account in order to publish ads. In other words, remember that you need to pay for clicks or impressions through the Facebook ad account to run your campaigns through our tool.
To set up a funding source in Facebook go to www.facebook.com/ads/manage. Select your ad account and click on Billing in the left hand sidebar. In the billings tab you can change or set up the funding source.
