+# Custom HTTP Client
+ 
+The Python SDK makes API calls using the (requests)[https://pypi.org/project/requests/] HTTP library.  In order to provide a convenient way to configure timeouts, cookies, proxies, custom headers, and other low-level configuration, you can initialize the SDK client with a custom `requests.Session` object.
+
+
+For example, you could specify a header for every request that your sdk makes as follows:
+
+```python
+import unstructured_client
+import requests
+
+http_client = requests.Session()
+http_client.headers.update({'x-custom-header': 'someValue'})
+s = unstructured_client.UnstructuredClient(client: http_client)
+```
+
+
+<!-- End Custom HTTP Client -->
