Create A Software Bot To Interact With eMail and uDemy

I would like a piece of software that will do this after a sale is made from my websites. I will either use paypal, jvzoo, or clickbank. 1) get sales email and cut the paypal, jvzoo, or clickbank receipt number from the email 2) login to [login to view URL] and go through the steps to create a redemption code using the cut receipt from 1) So when the customer buys they will get delivery of the product via udemy.com. Their receipt will be used by them as redemption code to gain access to the product. Some variables. 1) [login to view URL] redemption code with be set to receipt, with a $0.00 cost, and a one time use for the code so the receipt can not be shared. 2) will be doing multiple products so not sure if it is best to have one email for delivery, and have the software determine which product is being used, or have a separate email for each product and have the software login to many different emails. That is the software I need.
