PayPal IPN

Post by alex.barylski »

I need to implement a subscribtion service and wish to use PayPal and their recurring payments system...I have contacted their support twice now and haven't heard anything...so I figured I'd ask here:

1. Using their Subscription service does it automatically debit their CC every X days (30 in my case) or does it send them a notice which requires them to login and pay each month -- that would be a PITA for me and client.

2. Using their subscription service and IPN it seems I would be able to automate most of the payments. My concern is, as a web service fees will vary per client. At best I can charge clients a fixed amount each month depending on usage. So if they use 50GB bandwidth I charge them $15/month if they use 50-100GB I charge them $30/month. How is somehting like this handled with PayPal? Would I need to check their accounts with a CRON and send an email asking them to upgrade to a high service level? Or is there a way using IPN to custom bill a client X number of dollars every month, while continuing to use the subscription service?

Cheers
Alex
