View Shopify JSON data without API keys or creating a private app

While logged into your Shopify store, you can access any GET route in Shopify's REST API and view json data. For example, /admin/api/2022-10/products.json is a GET request you can use, but just remove the /admin/api/2022-10 and add products.json to the end of your store url and you will see json data.

You can do this to any GET request route and even use the fields parameter to only get the part of data you need. https://shopify.dev/api/admin-rest
