The Custom Activities in the custom-activity-deskapi-node example application include a version name/value pair in the metaData object in the config.json files:

    "workflowApiVersion": "1.0",
    "metaData": {
        "version": "2.0",
        "icon": "images/jb-icon.jpg",
        "iconSmall": "images/jb-icon.jpg"

I can't find any documentation related to this version number. Can someone clarify:

  1. Is this name/value pair required in a Custom Activity?
  2. Is this version number a developer-assigned iterative version number for the Custom Activity? Or does it have a specific role within an Interaction?

You can set it to anything. It's just the version number of your development iteration for that particular activity. In the custom activity example I pulled version from package.json to display in the configuration. But it could instead be pulled from this metaData version.
