Hi, i am using PayPal PreApproved payments for my crowd funding website, where where project backers are only charged if the project is successfully backed (similar to kickstarter) I am worried that a high rate of payments will fail when the PayPal API tries to collect the funds when a project is successful: - a backer might not have any funds in their PayPal account - a backer might close their account once the project is succssful (to intentionally stop payment) - a backer might remove / cancel their preapproved payment - etc... There are a number of ways that the payment could fail which would mean that the project owner would not get the funds. Can anyone suggest a way of tightening or securing preapproved payments? Please note, that PayPal will only allow you to use PreApproved payments for a crowdfunding website. Please also note that project owners need to be able to receive the funds from my site. Sometimes, these funds can be as small as $10 or up to $10,000 so we need to use PayPal to pay them as there is no other automated way of getting the funds to the project owner
