# Override Configuration Parameters

In actions that you send to Media Server, you can override some configuration parameters that are set in a configuration file.

To send new parameter values with an action, add the following to the action that you are sending:

    &[ConfigSection]ParameterName=NewParameterValue

where:

`ConfigSection` | is the name of the configuration section that contains the parameter to override.
`ParameterName` | is the name of the configuration parameter to override.
`NewParameterValue` | is the new value to set.

For example, to override the `Orientation` configuration parameter for barcode analysis, in a single `process` action without changing the configuration file:

    localhost:14000/action=process&configname=barcodes
                                  &source=./media/document.pdf
                                  &[BarcodeAnalysisTaskName]Orientation=Any
