The Measurement Protocol enriches client-side data with server-side insights, improving segmentation. Reserved property names and prefixes cannot be used. Server code can augment client events with user properties like `customer_tier`. Timestamps for properties are prioritized from individual entries to request level, and the most recent property value is used. Overriding timestamps is crucial for historical data.\n"]]
