Use credit card as a payment method:
Once you have completed your campaign settings and added your creatives, go to the Payment step.
Under the Payment method select Credit Card. If you have added cards to your account, you'll see a list of all of your cards. You can just select the one you want to use for payment of this campaign, or add a new one by clicking the '+ Add new card' link.
Optionally, you can decide if you want to use your Account Balance before your card is charged whenever there are funds in the account that can be used to pay for this campaign.
You must also confirm that you agree with the payment terms ('I agree and understand that all payments are done in advance...'). After the billing frequency is changed, you'll see a Preliminary payment schedule for your campaign with all the upcoming payment dates and amounts.
In the next step, select how often you want your card to be charged by choosing the billing frequency. Note here that all payments are done in advance, and your card will be automatically charged as long as you have this campaign running. To prevent your campaign from pausing, billing will occur 3 days before the current billing period ends.
The last setting, Funds sharing, allows you to automatically share funds with other campaigns or the subscription plan.
