We have been Amazon's affiliate for a little while (not long) and we are now starting implementing PA API 5.0.
Up till now, we used to build our affiliate referral links to the products through our CMS following this structure below:
amazon.com/[product-slug]/dp/[ASIN-code]/ref=nosim&tag=[our-affiliate-tag-code]
(variables between square brackets)
The links that are being fed to us through the PA API 5.0 (via scratch pad for now), however, have a different structure:
amazon.com/dp/[ASIN-code]?tag=[our-affiliate-tag-code]&linkCode=osi&th=1&psc=1
The ASIN and our tag are still there, of course, but what about the other codes? What about the ref=nosim as opposed to the new linkCode=osi&th=1&psc=1 ???
Is the former URL structure still valid? Would it still assign the sale as a valid sale for keeping access to the API? Do we need to replace all our old links?
Please advise. Thanks, David
