Building Amazon Affiliates links

Question

How can I generate an Amazon affiliates link (with my Tracking ID) from a regular link without using Amazon online tools ?

Answer 1

Here's an easy tutorial that should get you started. And this page at Amazon should fill in some gaps about ASINs, especially the section entitled: "Is there an automated way to create Associates links if I have the 13-digit ISBN?" Here's another relevant article.

You are not very specific on how you want to generate them or how many you will be generating, but there's an online tool written by Eri Robillard that uses WebForms and XML Web Services. If it's a small number of links you want to make by hand, it looks like a good tool.
If you're looking to generate them programatically, you might be able to get permission from him to screenscrape his site, or maybe he'd provide you with source code. I can't find what restrictions (if any) he puts on its use.
