Paypal/Oscommerce Credit Transaction in admin

Hello. I am using oscommerce ([login to view URL]) on a very popular e-commerce site. Our only method of payment on the site is Credit Card or Paypal Express Both of which are processed through paypal via the paypal payments pro service. This includes Paypal Express payments and regular credit card payments all processed through paypal via the "PayPal Pro Direct Payments & Express Checkout" module found here: (latest version)<[login to view URL],3647/category,all/search,paypal+express> What I need is a backend PHP script that I can call from a url (we will install a simply button in admin/[login to view URL] page) to credit back tranactions for refunds, canceled orders.. etc. The programmer must know how oscommerce and this Paypal module works since you will need to pull the origional paypal transaction number for that order, then credit that transaction for a specific amount. (I think the origional transaction number can only be found in comments for that order, but I may be wrong) My only requirements are that the script prompt for the amount to refund via a input box, not to exceed the origional charged amount (easy sql query to get origonal transaction amount) The output must be an error or success message with the refunds tranasaction number so we can manually copy and paste it into the comments box to update the order. I will personally do all integration I just need someone to write the php code to get this done --- my schedule is way too backed up or I would do it myself. Programmer needs to know the paypal API and the paypal express / direct payments module well. The code needs to be written in easy to read form, not encryped (the more comments in the code the better) Thanks - Ryan ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
