# Metadata API

The Metadata API provides a seamless way to view additional object definitions (i.e., metadata).

The Metadata **objects** field will display unified object types as keys, and the corresponding values will be arrays of IDs associated with those objects.

For example:

```
{
  "objects": {
    "commerce_item": ["item1", "item2"],
    "commerce_collection": ["collection1", "collection2"],
    "commerce_item_variant": ["variant1", "variant2"]
  }
}

```

The Metadata API enhances the `commerce_metadata `object, which is being deprecated. The API is being released starting with **commerce\_item**, **commerce\_collection**, and **commerce\_item\_variant** with expanded support for other unified models coming in the future.
