Auto-Updating Amazon Affiliate Links

I need Amazon Affiliates integration added to each product page so that the price, availability, and buy button all update automatically whenever Amazon changes them. The goal is to stay compliant with Amazon Associates while keeping my catalogue accurate without manual edits.

The work involves connecting the product pages to the Amazon Product Advertising API (or another fully compliant solution), embedding my tracking ID in every link, and scheduling regular price checks so the displayed figure, currency, and stock message refresh in the background. Page-load speed and the current layout must remain unaffected.

Once the system is live, I will also need a short, step-by-step guide that shows me how to add new products or swap out the tracking ID in the future.

Please outline the approach or plugin you plan to use, any rate-limit or caching considerations, and an estimated timeline for delivery so we can move forward right away.
