Metaobjects are custom data structures that your app can define and create to store your app's information. Similar to metafields, they can be associated with a Shopify resource such as a product or a collection. However, they can also exist on their own. Metaobjects provide you with a way to create resources that Shopify doesn't offer out of the box.

Users can define their own metaobjects or use the ones that your app creates to extend their shop's data model. Metaobjects are also available in themes using Liquid, Storefront API, and Admin API.
