+## Connect to the Milvus RESTful server with TLS
+
+For RESTful APIs, you can check tls by using the `curl` command.
+
+### One-way TLS connection
+
+```bash
+curl --cacert path_to/ca.pem https://localhost:19530/v2/vectordb/collections/list
+```
+
+### Two-way TLS connection
+
+```bash
+curl --cert path_to/client.pem --key path_to/client.key --cacert path_to/ca.pem https://localhost:19530/v2/vectordb/collections/list
