Once your action is created, you can add, change, or delete its parameters in the Action Parameters Editor. How?

You have to create one action parameter for each C# or Java parameter of the corresponding method. The order of the parameters must be the same both in the extension action and in the corresponding C# or Java method.

The operations for handling the order of the parameters are available on the right-side of the Parameters table or in the right-click menu of the parameter. See Action Parameters Editor.
