Easy Tech TutsHow to Replace the Add to Cart or Buy Now Button on Shopify and Redirect it to an External Affiliate
By Impran M N
Running an affiliate-style Shopify store means sending shoppers to another marketplace instead of your own checkout, and that requires editing the button behavior directly. This guide covers locating the right button snippet in your theme code and replacing the checkout link with your affiliate URL for both Buy Now and Add to Cart buttons.
01Understand why you'd redirect to an affiliate link
If you're running an affiliate store, sending customers to another marketplace or supplier's product page instead of your own checkout is often the whole point of the setup.
02Locate the button code in the theme editor
Open your theme's code editor and find the snippet responsible for the Add to Cart or Buy Now button behavior.
03Add a custom affiliate redirect link
Replace the existing checkout link in that snippet with your affiliate URL so clicking the button sends visitors off-site instead.
04Review final tips for an affiliate Shopify store
Once the redirect is working for both button types, double-check that the experience still looks professional and consistent with the rest of your store.
