Yes, you can send an app version through the Google Analytics Measurement Protocol API. However, it’s important to note that the way user properties are defined and utilized in Google Analytics 4 is different than previous versions. User properties in GA4 are typically registered and managed in the GA4 UI, so it appears they must be predefined before they can be attached to events or used in filters. To have the application name and version attached to the events, you need to first register these properties (app_name and app_version) in the GA4 UI. This is a change from previous versions where you could just send these properties with your hits without previously defining them. If you have already registered these properties and they are not showing up, it could be due to a data delay in GA4 or potential issues with the way these properties are defined in your code. There is also the chance of an error or delay with the Measurement Protocol API data being processed or appearing in your reports. It may take up to 24 hours for this data to appear.
