Hi Nirmita,
thanks for the quick reply.
I've probably provided not enough information.
We already checked out the guide you provided and we couldn't find a solution that fits our needs.
We have some ConversionAction in our App, which is linked to Google Ads Via firebase, and we're able to fetch them via API.
From the UI we can create an App User segment where we can select the app, the Conversion Action, AND refine the action by providing a specific parameter and a value. (UI result is the "This action must match every parameter below" part)
We're struggling with this last point. We aren't able to figure out how to Refine the UserList's Conversion Action with additional parameters and values via API.
Hope this will help to figure out what's our problem.
Thanks
Lorenzo
