``ros2 param`` uses the parameter service API as described above to perform the various operations.
See :doc:`this how-to guide <../../How-To-Guides/Using-ros2-param>` for details on how to use ``ros2 param``.

In addition to the command-line interface, parameters can also be manipulated programmatically at runtime using the ROS 2 client libraries.
All client libraries provide APIs to get, set, and react to parameter changes while a node is running.

Client library support includes:
* **C++ (rclcpp)**: see :doc:`../../Tutorials/Beginner-Client-Libraries/Using-Parameters-In-A-Class-CPP` and :doc:`../../Tutorials/Intermediate/Monitoring-For-Parameter-Changes-CPP`.
* **Python (rclpy)**: see :doc:`../../Tutorials/Beginner-Client-Libraries/Using-Parameters-In-A-Class-Python` and :doc:`../../Tutorials/Intermediate/Monitoring-For-Parameter-Changes-Python`.
