We are looking to get a dummy project using ASP .Net Web Form and C# and Paypal SDK.
Website provides online data subscription which is charged per month at a fee and user can upgrade or downgrade the subscription. Price is on pro rata basis so if user upgrades in the middle of the month then we charge for remaining month and from 1st of every month we charge the original price. If user downgrades then the fee has to be adjusted for next month. No refund is given.
Based on this we are looking to get a working sample C# code on how to authorize a user Paypal account, setup agreement, authorize, execute and charge user. Also how to delete or change agreement using Paypal SDK.
