+# Proxy Support
+
+In certain cases, your corporate IT infrastructure may encounter issues with HTTPS requests, leading to SSL certificate errors. To resolve this, HTTP and HTTPS proxies can be passed into all API wrappers as shown in the example below. If you're unsure about which proxies to use, please consult your company's IT administrator.
+
+```python
+from sec_api import QueryApi, RenderApi, ...
+
+proxies = {
+  "http": "http://your-proxy.com",
+  "https": "https://your-proxy.com",
+}
+
+queryApi = QueryApi(api_key="YOUR_API_KEY", proxies=proxies)
+renderApi = RenderApi(api_key="YOUR_API_KEY", proxies=proxies)
+```
