We place a temporary authorization for all $100+ charges, which will be released within 72 hours. After 72 hours, you should see the authorization hold either refunded, or removed on your end.
Once we begin processing payments on the 1st of the month, you will be charged your actual pledge amount, which will be sent directly to the creator.
Note: If you were charged immediately for a pledge, learn more about "charging upfront" here.
