Need Advice About Pinterest Affiliate Marketing

I’m new to affiliate marketing and liked using the Pinterest platform to promote Amazon products. The guidance I heard was to create a Pinterest pin that directs users to your website/blog but most Pinterest pins seems to direct users to the product to buy which is what I like as a consumer. I’ve read you can’t send users from a pin directly to product site as Pinterest frowns on this. My question is, is it acceptable to create a Pinterest pin the points users to a product or do I need to build a website/blog to send users to?
