I need the services of a programmer who has used and worked extensively with Clickbanks ([login to view URL] ) API. I you've never worked with Clickbanks API, please don't bid. I need only programmers who have used this API. We are developing a software application which we will will be selling through the Clickbank networks, and from their API we need to we need to retrieve payment verification notifications each time a sale is made software is sold. Budget is $40. It should be a very quick solution for the experienced.
