Access to the Contacts API requires a valid GHL OAuth token with the scope set to contacts.readonly or higher. Use your Zapier App Connector credentials to obtain, refresh, and revoke tokens as needed.
Authorize the connection in Zapier using OAuth 2.0 or an API key and store credentials securely in the Zapier vault.

Trigger: A contact is updated in GHL, then Zapier fetches the latest data to synchronize records.
Actions: GET /contacts/:contactId and GET /contacts/:contactId/tasks to assemble a complete view for downstream automations.
Methods/Paths: GET /contacts/:contactId; GET /contacts/:contactId/tasks
Key fields: contactId, name, email, phone, company, tasks, notes
Trigger: A new or updated contact in GHL starts a create/update flow in Zapier.
Actions: POST /contacts/ to create, PUT /contacts/:contactId to update, POST /contacts/:contactId/tasks to attach tasks.
Methods/Paths: POST /contacts/; PUT /contacts/:contactId; POST /contacts/:contactId/tasks
Key fields: name, email, businessId, contactId, task list
Trigger: A scheduled batch sync pulls multiple contacts for updates.
Actions: GET /contacts/ and related endpoints like GET /contacts/:contactId/notes, POST /contacts/:contactId/tags, GET /contacts/:contactId/appointments as needed.
Methods/Paths: GET /contacts/; GET /contacts/:contactId/notes; POST /contacts/:contactId/tags; GET /contacts/:contactId/appointments
Key fields: contactId, notes, tags, appointments
Real-time data sync between GHL and Zapier without writing code.
Automated workflows that trigger on contact events and propagate updates automatically.
Centralized access to contact data for marketing, sales, and support teams across apps.
This glossary defines endpoint, trigger, action, field, and authentication as used in this guide.
A specific URL and HTTP method used to interact with the GHL API.
An event in GHL or Zapier that starts a workflow.
An operation performed by Zapier in response to a trigger.
The process of verifying identity to access the API.
Set up a Zap to create a default task whenever a new contact is created in GHL.
Automatically add notes and tags from external apps to GHL contacts.
Create calendar events or reminders when notes include due dates.
Ensure you have admin access to GHL and a Zapier account, and register the Zapier App Connector in your GHL integration settings.
Choose endpoints from the list (for example /contacts/:contactId and /contacts/:contactId/tasks) and map fields like name, email, and task data.
Run test workflows, simulate real-world data, and deploy to your live Zapier automations.
Yes. The core Contacts API is accessible via the Zapier App Connector. Start by testing GET /contacts/:contactId to pull a single contact, then expand to related resources like tasks and notes as needed. This keeps your initial setup simple and testable. The connector respects the scope defined in GHL (contacts.readonly by default) and allows you to raise permissions as your automation needs grow.
No advanced coding is required. Use Zapier’s visual builder to create triggers and actions against the listed endpoints. You can map fields, set filters, and chain steps without writing code. If you need bespoke logic, you can still add simple transformations within Zapier.
Begin with a basic flow using GET /contacts/:contactId to validate data retrieval. Then add related endpoints such as GET /contacts/:contactId/tasks to enrich the workflow. This phased approach helps verify mappings and avoids complexity at the start.
Security uses OAuth 2.0 or API keys, with token rotation and scope limitation. Store credentials securely in Zapier, enable least-privilege access, and monitor activity. Consider IP allowlisting if supported by your environment.
Yes. Zapier Schedule triggers or time-based batching can run periodic syncs (nightly or hourly). You can also use webhooks for real-time updates if supported by your workflow. Plan rate limits and backoff in your Zaps.
During a sync, existing records are updated by matching on contactId. Duplicates are avoided by using the contactId as the primary key. Conflicts can be resolved with field-level update rules you define in Zapier.
API rate limits depend on your GHL plan. Monitor response headers, implement exponential backoff, and contact support for higher quotas if needed. Caching and batching can help reduce peak call volumes.
Due to high volume, we will be upgrading our server soon!
