Hi

This is Victor from PageFly - Shopify Page Builder App

Depending on your theme, find your product.liquid (or product-template.liquid - or product-main.liquid). Please note that is .liquid not .json

And you can paste the affirm code on the top of the file

Hope this can help you solve the issue
