Azure Remote Monitoring - How to add parameters to CloudToDeviceMethods?

In Azure Remote Monitoring, you can create your own CloudToDeviceMethods. How do you add parameters to those methods?

Usually those methods look like this:

function main(context, previousState, previousProperties) { ... }

...in a .js file that has the name of a specific method. But I don't see how I can add parameters to a method like that. I also want to see those parameters in the Azure Remote Monitoring Solution Accelerator web, so I can call that method and send in some parameters.

A CloudToDeviceMethod supports exactly one parameter, and that is the JSON payload that you can give to it. Of course you can add many properties to that payload to act like separate parameters. On the device side, reading that parameter looks like this in C# and like this in JavaScript (Node example)

You mentioned that you want to be able to add those parameters in the Remote Monitoring Solution Accelerator. This is entirely possible with some changes to the ReactJS code. The main files you need to look at are the Job page, right now it calls the device method without a body. Eventually the request is built here, you can see the JsonPayload is left empty.
