If you're collecting event data across multiple services, you might want to filter your data for analytics to view a single domain or service. We recommend using app_id or a similar identifier for unstructured events to achieve this.
Using app_id
When configuring your tracker you can nominate a descriptive app_id to be associated with every event it processes. This field is captured on the atomic.events table and can be used within queries to limit the result set to a specific service.
Unstructured events
If you're capturing unstructured events, you can also use a custom field to store the website URL or similar identifier to app_id.
