+### GraphQL API
+This library also provides possibility to use [GraphQL API](https://developer.crowdin.com/graphql-api/) (only for Crowdin Enterprise).
+
+```python
+from crowdin_api import CrowdinClient
+
+client = CrowdinClient(
+    token='{token}',
+    organization='{organization}'
+)
+
+query = """
+query {
+  viewer {
+    id
+    name
+  }
+}
+"""
+
+# Execute the GraphQL query
+response = client.graphql(query=query)
+```
