Hi! You will need to add the `filters` query parameter in order to filter by a specific app. Your endpoint will look something like this: https://api.revenuecat.com/v2/projects/${project.id}/charts/actives?realtime=false&start_date=${dateStr}&end_date=${dateStr}&filters=[{"name":"app_id","values":["appabc123"]}] . You will need to make sure to use the full app ID with the ‘app' prefix as I have done in the example endpoint. You can find the other options for the filters parameter by using the endpoint mentioned in this section.
