Shop Feeds
Products RSS feed
If you're just looking to read public product information, you do not need to use Open API. All sites publish a Merchant Center Feed under an RSS address:
${shop_url}/.well-known/merchant-center/rss.xml
Example: for https://shop.fourthwall.com the RSS feed url would be https://shop.fourthwall.com/.well-known/merchant-center/rss.xml
Collections JSON feed
A JSON version of the products in a collection.
${shop_url}/collections/{slug}.json
Example: https://shop.fourthwall.com/collections/all.json or https://shop.fourthwall.com/collections/lax-poz.json
Paginated: https://shop.fourthwall.com/collections/all/2.json
