ga4-measurement-protocol

Server-side GA4 tracking uses the Measurement Protocol to POST events directly to Google Analytics from your backend. This enables tracking from payment processors, CRM systems, form handlers, and offline conversions where client-side tracking isn't possible, using your measurement ID, API secret, and client ID in the payload.

Generate a measurement protocol API secret in your GA4 property, then include it with your measurement ID and client ID in each POST request to the collect endpoint. Authentication is secret-based and endpoint-specific, supporting both production and debug endpoints for testing before going live.

Yes, the Measurement Protocol enables server-side tracking of offline conversions, CRM integrations, and backend events by sending structured JSON payloads with user properties, event names, and timestamps directly to GA4 without requiring client-side instrumentation.

Event names must not exceed 40 characters, requests can include up to 25 events per batch, and payloads require client_id or user_id, measurement_id, API_secret, and properly formatted events arrays with user properties and consent signals for compliance.

Implement retry logic and rate-limit handling in your backend to manage API responses when batching events via Measurement Protocol. The Skill covers error handling strategies to ensure reliable delivery of server-side events to GA4.

Yes, Measurement Protocol is designed for headless CMS platforms, backend form processors, and any server-side system that needs to track events without client-side JavaScript, using standard HTTP POST requests with validated JSON payloads.
