Use your GHL API credentials for the Contacts API with the scope: contacts.readonly. This enables read access to contacts, tasks, notes, and related data for your automations.
In Zapier, connect the App Connector to your GHL account using the supported method (OAuth or API key) and grant the requested scopes to allow data flow between Apps.
Core endpoints used in this integration include: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/tasks/:taskId, GET /contacts/:contactId/notes, GET /contacts/:contactId/notes/:id, GET /contacts/:contactId/appointments, GET /contacts/, GET /contacts/business/:businessId, contacts.write, POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, DELETE /contacts/:contactId/tasks/:taskId, POST /contacts/:contactId/tags
Trigger when a contact is created or updated in GHL and pull fresh data into Zapier.
Actions: Retrieve contact details, tasks, notes; optionally create or update related items.
Endpoint used: GET /contacts/:contactId
Key fields: contactId, name, email, phone
Trigger in Zapier when an app action requires syncing contact changes.
Actions: Update contact details, add tags or notes.
Endpoint used: PUT /contacts/:contactId
Key fields: contactId, fields updated
Trigger: new lead created in Zapier to create in GHL.
Actions: POST /contacts/ to create; set initial tasks or notes.
Endpoint used: POST /contacts/
Key fields: name, email, phone, businessId
Automate CRM tasks without writing code, reducing manual data entry.
Create end-to-end workflows that move data between GHL and your apps with ease.
Scale operations using reusable Zap templates for common processes.
Understand core parts: endpoints, triggers, actions, and fields to design reliable automations.
Application Programming Interface: a set of rules that lets apps talk to one another.
A specific URL path used to access a resource via the API.
An event in one app that starts a Zap in the Zapier App Connector.
An operation performed in response to a trigger, such as creating or updating a record.
When a form fills, automatically create a contact in GHL and assign a welcome task.
Push ticket updates into contact notes to keep history in one place.
Tag contacts based on form responses and activity to enable segmentation.
In Zapier, choose the App Connector and authorize the GHL account.
Select the endpoints you need (e.g., GET /contacts/:contactId, POST /contacts/).
Test the data flow and adjust mappings as needed.
You can authenticate using OAuth or API keys depending on what your GHL account supports. For most setups, OAuth provides a secure, token-based flow, while API keys offer a straightforward alternative. Always ensure the scope includes at least contacts.readonly to access necessary data. If you need write access for automation, coordinate with your GHL admin to grant intended scopes in a controlled way.
Endpoint access includes common read endpoints such as GET /contacts/:contactId and related resources like tasks, notes, and appointments, plus bulk read with GET /contacts/. Write endpoints like POST /contacts/ and PUT /contacts/:contactId enable automation workflows. Use the included endpoint list as a guide for building your Zapier automations.
No extensive coding is required. The Zapier App Connector provides a no-code interface to map fields and set triggers and actions. Some familiarity with REST endpoints helps, but you can build powerful automations using prebuilt templates and drag-and-drop configuration.
To test your connection, run a test Zap in Zapier that pulls a sample contact record from GHL and validates that fields map correctly. Check authentication, endpoint responses, and field mappings. Adjust scopes and mappings if any errors appear.
Yes. You can update existing contacts via PUT /contacts/:contactId, update tasks, or add notes and tags. Ensure your Zapier actions target the correct contactId and that your user has the necessary write permissions.
Security is handled via OAuth or API keys with scoped permissions. Always limit scopes to the minimum needed for automation, and consider using test accounts for development. Review endpoint access controls and audit logs in GHL to monitor activity.
Endpoint details are documented in the integration guide and reflect the 17 core endpoints listed above. Your Zapier setup will reference these endpoints when designing triggers and actions. If you need additional endpoints, consult your GHL API docs or contact support.
Due to high volume, we will be upgrading our server soon!
