+### Receiving a raw response
+
+The `request` method will return the `data` or `errors` key from the response.
+If you need to access the `extensions` key you can use the `rawRequest` method:
+
+```js
+import { rawRequest } from 'graphql-request'
+
+const query = `{
+  Movie(title: "Inception") {
+    releaseDate
+    actors {
+      name
+    }
+  }
+}`
+
+rawRequest('my-endpoint', query).then(({data, extensions}) => console.log(data, extensions))
+```
+
