To utilize this store you will import the COLLECTIONS_STORE_KEY in any module referencing it. Assuming `@woocommerce/block-data` is registered as an external pointing to `wc.wcBlocksData` you can import the key via:
```js
import { COLLECTIONS_STORE_KEY } from '@woocommerce/block-data';
| `queryString` | string | An additional query string to add to the request for the collection. Note, collections are cached by the query string. (eg. '?order=ASC') |
| `ids` | array | If the collection route has placeholders for ids, you provide them via this argument in the order of how the placeholders appear in the route |
| `response` | Object | An object containing a `items` property with the collection items from the response (array), and a `headers` property that is matches the `window.Headers` interface containing the headers from the response. |
| `replace` | boolean | Whether or not to replace any existing items in the store for the given indexes (namespace, resourceName, queryString) if there are already values in the store |
This selector will return the collection for the given arguments. It has a sibling resolver, so if the selector has never been resolved, the resolver will make a request to the server for the collection and dispatch results to the store.
This selector will return a header from the collection response using the given arguments. It has a sibling resolver that will resolve `getCollection` using the arguments if that has never been resolved.
If the collection has headers but not a matching header for the given `header` argument, then `undefined` will be returned.
If the collection does not have any matching headers for the given arguments, then `null` is returned.
