Authenticate with your GHL account using the provided API credentials. Use OAuth 2.0 when available or the supported API key method, ensuring the correct scopes (e.g., contacts.readonly and contacts.write) are granted.
In Zapier, create a new connection to the Contacts API using OAuth credentials or an API key, then select this connection when building your Zap.
Key endpoints used in this integration: – GET /contacts/:contactId (fetch a single contact) – GET /contacts/:contactId/tasks (list tasks for a contact) – GET /contacts/:contactId/tasks/:taskId (read a specific task) – GET /contacts/:contactId/notes (list notes) – GET /contacts/:contactId/notes/:id (read a note) – GET /contacts/:contactId/appointments (list appointments) – GET /contacts/ (list contacts) – GET /contacts/business/:businessId (fetch business-related contacts) – POST /contacts/ (create a contact) – PUT /contacts/:contactId (update a contact) – DELETE /contacts/:contactId (delete a contact) – POST /contacts/:contactId/tasks (create a task) – PUT /contacts/:contactId/tasks/:taskId (update a task) – PUT /contacts/:contactId/tasks/:taskId/completed (mark task complete) – DELETE /contacts/:contactId/tasks/:taskId (delete a task) – POST /contacts/:contactId/tags (add tags to a contact) Permissions: contacts.write
Trigger: New or Updated Contact in GHL via GET /contacts and watch changes, firing every 15 minutes.
Action: Write contact data to a spreadsheet, CRM, or data warehouse with fields like contactId, name, email, tags, and lastUpdated.
GET /contacts
contactId, name, email, phone, tags
Trigger: New task requested for a contact via POST /contacts/:contactId/tasks or when a task is created by another app.
Action: Create a corresponding task in a project tool and optionally update the contact with taskId and status.
POST /contacts/:contactId/tasks
contactId, taskId, taskName, status, dueDate
Trigger: Notes added or tags updated on a contact (POST /contacts/:contactId/notes, POST /contacts/:contactId/tags)
Action: Push tags to downstream apps, segment lists, or update CRM fields.
POST /contacts/:contactId/notes and POST /contacts/:contactId/tags
contactId, noteId, tagNames
Drag-and-drop Zap editor lets you build automations quickly without coding.
Automations run in the background, freeing your team to focus on more strategic work.
Seamless data flow between GHL, Sheets, CRMs, and task tools accelerates processes.
Core concepts you’ll encounter: API endpoint, authentication, triggers, actions, methods, and payloads that power Zapier integrations with GHL.
A defined URL and operation exposed by the API to perform a function, for example GET /contacts/:contactId fetches a single contact.
The process of proving identity to access the API, typically via OAuth tokens or API keys.
An event in GHL that starts a Zapier workflow, such as a new or updated contact.
An operation executed in response to a trigger, such as creating a task or updating notes.
Use an Email Parser by Zapier trigger to extract contact details and create or update a GHL contact via the Contacts API.
When an email arrives, create a task in GHL and link it to the contact using /contacts/:contactId/tasks.
Assign tags via POST /contacts/:contactId/tags depending on parsed sentiment fields.
In Zapier, add a new connection and choose OAuth or API key authentication for the Contacts API.
Select GET /contacts and map fields you want sent to downstream apps.
Map contact fields to your destination and test the Zap to confirm data flows correctly.
No coding is required for most Zapier connections. Use Zapier’s built-in triggers and actions to map GHL Contacts API fields to your apps. If you need more control, review the authentication setup and test steps. If you encounter rate limits, adjust polling frequency or switch to webhooks (if supported) to minimize calls.
For a basic two-way sync you typically use GET /contacts and GET /contacts/:contactId to retrieve data. You may also need POST /contacts/ to create or PUT /contacts/:contactId to update. Start with a limited field set and expand as needed.
Supported methods include OAuth 2.0 and API keys. Choose the method when creating the Zapier connection and refresh tokens or keys as required by the provider.
Test by running a sample Zap with a test contact and verify the destination app receives the data correctly. Check the connection status in Zapier and review logs for any errors.
Yes. Triggers and actions can pass data to external apps, enabling cross-system workflows. Use endpoints like /contacts/:contactId/tasks or /contacts/:contactId/notes to drive downstream updates.
Rate limits apply to API calls; plan your polling intervals and batch requests where possible. Consider using webhooks or conditional triggers to minimize unnecessary calls.
Endoints and docs are available in the official API reference and the page you are reading. Search for the Contacts API endpoints section in your GHL API docs.
Due to high volume, we will be upgrading our server soon!
