Why is money held on PayPal before my charging session?
Like for the other payment methods, to confirm that sufficient funds are available for your charging session, a temporary hold (pre-authorization) is placed on your PayPal account. This is a standard procedure and does not constitute an actual charge, although you may receive a payment confirmation email from PayPal.
The final payment will be processed only after your session is complete, based on your actual usage. Any unused portion of the pre-authorized amount will be automatically released back to your PayPal account.
Why do I see a PayPal confirmation email if no money has been charged yet?
PayPal may send you a payment confirmation email when the pre-authorization is placed. This is standard behavior from PayPal but it does not indicate a completed transaction.
You can always check the real-time status of this pre-authorization directly in the PayPal app or on your PayPal account dashboard: any temporary holds will be visible there.
