Measurement Protocol
01 Definition
Measurement Protocol meaning: A Google Analytics interface for sending event data to a property using direct requests.
The Measurement Protocol lets you send events to Google Analytics through server-to-server HTTP requests instead of the standard on-page tracking. It supports use cases like offline conversions or backend events. The GA4 version requires an API secret and matching identifiers, and hits must follow its rules to be processed.

Why it matters
How Measurement Protocol fits the work
It extends measurement beyond the browser, so you can record actions that happen on servers or offline and connect them to online activity in one property.
In context
A team uses the GA4 Measurement Protocol to send a refund event from its server when a support agent cancels an order after the sale.
Practical note
Hits need a valid client ID or user ID to join existing sessions, and Google may not process malformed or non-compliant requests. It cannot fabricate data Google would reject as invalid.
