Adding a new credit card payment method

You can create and save a new campaign without payment information, but in order to launch an ad group, you must have a valid credit card on file. 

Note: To validate the authenticity of your credit card, a $1 charge will be applied to the card. This hold will be reversed in 7 to 10 business days.

This section will show you how to add a new, edit, or update a payment card to your account. If you wish to be invoiced instead, please email for support.

Add a new payment method

You can add a credit card in one of two ways:

  1. During Ad Group Creation: When you save and launch a new ad group for the first time, you'll be prompted to enter your credit card information if you haven't already added one.
  2. Through the Billing Menu: You can also add a new credit card at any time by following these steps:
    • Log in to your GroundTruth Ads Manager account.
    • Click on the hamburger menu in the top left corner.
    • Select "Billing" from the dropdown menu.
    • On the Billing page, click "Add Payment Method". Enter your credit card details and click "Save".

Note: Pre-paid cards, gift cards — including those branded Visa, Mastercard, and American Express — ATM cards (debit cards), and digital wallets such as PayPal and Venmo cannot be accepted as a form of billing payment.

Frequently Asked Questions

  1. Can I upload multiple credit cards? By default, only one credit card can be on file at a time. If you need to add multiple credit cards, please contact your account representative or email us at
  2. What happens if my campaign over-delivers? Credit cards that surpass the campaign budget specified by the user will be credited on the end-of-the-month invoice for any excess charges incurred. For instance, if your budget is $1000 and your campaign expenditure totals $800, you will be invoiced $800. However, if the campaign spending reaches $1200, you will be credited $200 at the close of the month.
  3. How does pricing work? GroundTruth charges based on CPM (cost per thousand impressions). There are minimum CPMs depending on the campaign type (mobile, desktop, video, OTT/CTV). Our minimum CPM price for both Mobile and Desktop targeting is $3.5. We recommend $10 - $15 for event/short flight campaign. For optimal pacing on video campaigns on Mobile and Desktop, we recommend starting with a $8 CPM. For OTT and CTV campaigns, our base CPM price is $25 across all screens.
