Requests to the Contacts API are authorized with OAuth 2.0 Bearer tokens issued by GHL. Use the read only scope to access contacts data.
To authorize the Zapier connection, create a new connection to GHL in Zapier and grant permissions. Zapier securely stores tokens for ongoing data transfers.

Trigger: a contact is created or updated in GHL triggers a GA4 event via Zapier
Actions: send events to GA4, map contact fields to GA4 user properties
HTTP method: GET at /contacts/:contactId
Key fields: contactId, email, fullName, lastActivity
Trigger: when a new contact is added or updated in GHL
Actions: fire GA4 events for new/updated contacts and update GA4 audiences
HTTP method: GET at /contacts/
Key fields: contactId, email, segments, businessId
Trigger: notes or tasks are created or updated for a contact
Actions: send GA4 events with noteTask details and mapped fields
HTTP methods: GET /contacts/:contactId/notes and GET /contacts/:contactId/tasks
Key fields: contactId, noteId, taskId, content, status
No coding required. Use the Zapier App Connector templates to route GHL data to GA4 with simple triggers and actions.
Fast setup with reusable templates, triggers, and actions to get GA4 tracking up quickly.
Automates data synchronization and GA4 event tracking between GHL and GA4 without custom development.
This section defines the data elements and processes used to connect GHL through the API to GA4.
The GHL API exposes contacts tasks notes and other resources via REST endpoints.
An GA4 Event records an action like contact created or task updated with parameters.
GA4 Audience groups users based on events and user properties.
Mapping GHL data fields to GA4 dimensions and metrics for analytics.
Trigger GA4 events as soon as a contact is created or updated in GHL
Track task creation and completion as GA4 events to measure engagement
Attach notes details to GA4 events for richer customer context
In Zapier, select the GHL Contacts API as the trigger source and authorize access
Set up triggers such as contact created or updated and map to GA4 events
Test end‑to‑end and deploy to run automatically
No coding is required when using the Zapier App Connector to map fields and set triggers. Prebuilt templates let you route GHL data to GA4 with drag‑and‑drop configuration. If custom mappings are needed, you can add them inside Zapier and save as a template for reuse.
GA4 can track standard events like page_view and user_engagement as well as custom events. You can send events for contact creation, task updates, and notes, and store additional properties in GA4 custom dimensions for richer analysis.
Map GHL fields such as email name and last activity to GA4 dimensions and metrics. Create a mapping template in Zapier to reuse across contacts and campaigns.
Yes. Use Zapier filters to limit what is sent to GA4 based on businessId or contact type. This helps tailor analytics to specific segments.
Zapier handles the OAuth 2.0 flow for you. You authorize the GHL connection in Zapier once, and tokens are refreshed automatically without code.
If data gaps occur, verify token validity and permissions, check endpoint availability, review field mappings, and test the Zap with GA4 Real-Time reports to confirm events are arriving.
Data sync frequency depends on your Zapier plan and configuration. Real‑time updates are possible with webhooks if your GHL setup supports them.
Due to high volume, we will be upgrading our server soon!
