To access the Contacts API, securely authenticate using OAuth2 or an API Key, and ensure your integration has the scope: contacts.readonly.
In Zapier, create a new connection to the GHL Contacts API and grant the necessary permissions to read and write contact data.
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; write: 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, Zapier can start a task automatically.
Actions: Create task (POST /contacts/:contactId/tasks), update contact fields, add notes.
POST /contacts/:contactId/tasks
contactId, taskId, title, dueDate
Trigger: a note or tag is added/updated for a contact in GHL
Actions: POST /contacts/:contactId/notes; POST /contacts/:contactId/tags
POST /contacts/:contactId/notes
contactId, noteId, tag
Trigger: an appointment or business record changes for a contact
Actions: GET /contacts/:contactId/appointments; GET /contacts/business/:businessId
GET /contacts/:contactId/appointments
contactId, appointmentId, businessId
Automate two-way data flow between GHL and your apps without writing code.
Coordinate tasks, notes, and appointments across platforms in real time.
Build end-to-end funnels that trigger direct mail workflows automatically.
This guide uses common API terms, triggers, actions, and data fields to help you design reliable automations.
Application Programming Interface: a set of rules that allows apps to communicate and share data.
OAuth2 is an authorization framework that lets apps access data securely without sharing passwords.
A URL path in an API that performs an action or returns data.
A method for apps to send real-time data to other apps via HTTP callbacks.
Capture leads from landing pages and automatically create or update Contacts in GHL, then trigger related tasks and follow-ups.
Use events from connected apps to apply lifecycle tags and remind teams with tasks and notes.
Trigger direct mail campaigns when contact criteria are met and reflect responses in GHL.
In Zapier, select the GHL Contacts API and authorize access to read and write data.
Pick a trigger such as ‘New Contact’ or ‘Contact Updated’ to start your workflow.
Define actions like creating tasks, notes, or updating contact fields in GHL.
All endpoints listed in the endpoint list cover common read and write operations for contacts, tasks, notes, and appointments. Use GET to retrieve data, POST to create, PUT to update, and DELETE to remove resources as needed. Access to endpoints requires a valid GHL API connection with the appropriate scope. For example, GET /contacts/:contactId fetches a contact, while POST /contacts/:contactId/tasks creates a new task tied to that contact.
No coding is required. This integration is built for no-code automation via Zapier App Connector, enabling you to connect GHL Contacts API with your apps using triggers, actions, and simple mappings. Advanced users can still customize workflows with multi-step Zaps if needed.
The scope noted for read-only access is ‘contacts.readonly’. If you need write access, ensure the connection includes write permissions where supported (e.g., creating contacts, tasks, notes). Always follow least-privilege principles and secure your API keys.
Yes. The Contacts API supports write endpoints such as POST /contacts/, PUT /contacts/:contactId, and POST /contacts/:contactId/tasks among others. Use these in Zapier to update or enrich your CRM data automatically. Make sure your connection has the required write scope.
You can create or attach notes with POST /contacts/:contactId/notes and apply tags with POST /contacts/:contactId/tags. These endpoints help you enrich contact records from automated workflows. Always verify the exact payload structure in the endpoint documentation.
Authenticate by configuring an API connection in Zapier to the GHL Contacts API using OAuth2 or an API key as supported by your GHL setup. Test the connection and ensure the app has the needed read/write permissions. Store credentials securely and rotate keys regularly.
Endpoint documentation is accessible in your GHL developer portal and the Zapier app connector docs. You’ll find endpoint paths, supported methods, and sample payloads there. Use the examples to model your Zaps.
Due to high volume, we will be upgrading our server soon!
