To use the Contacts API from Zapier, authenticate with your GHL credentials and grant the appropriate scope. Start with read-only access (contacts.readonly) for safety, and upgrade to write permissions only if your workflow requires it.
In Zapier, connections securely store credentials and authorize requests to the GHL Contacts API. Use OAuth2 when available or an API key/secret flow, then select the Contacts API as your target endpoint.
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; Action: pull the current contact data into Zapier.
Actions: fetch contact details, pull related tasks and notes, and sync basic fields to other apps.
GET /contacts/:contactId
Key fields: contactId, firstName, lastName, email, phone
Trigger: on a scheduled interval or batch; Action: retrieve multiple contacts.
Actions: list all contacts, filter by criteria, export to CSV or another app.
GET /contacts/
Key fields: contactId, name, email, phone, tags
Trigger: new or updated notes/tasks in GHL; Action: create corresponding tasks/notes via Zapier.
Actions: POST /contacts/:contactId/tasks, POST /contacts/:contactId/notes

Key fields: contactId, taskTitle, dueDate, notes
No-code automation lets you build complex workflows without writing a line of code.
Fast setup and deployment across teams and apps.
Real-time data syncing to keep all tools in sync.
This section covers endpoints, authentication, triggers, actions, and data mapping essential to building GHL + Zapier automations.
GHL API is the programmatic interface that lets you read and manage contacts, tasks, notes, and appointments in your GHL account.
A webhook is a real-time notification that fires when a defined event occurs in your app, allowing Zapier to react automatically.
OAuth is a secure authorization framework used to grant limited access to your GHL data without sharing passwords.
An API endpoint is a specific URL and method you call to perform an action, such as GET /contacts/:contactId.
Trigger a welcome workflow in Zapier when a new contact is added in GHL.
Automatically create follow-up tasks in GHL from Zapier when a deal moves stages.
Sync calendar events between GHL and your calendar app via Zapier.
Create a GHL connection in Zapier using OAuth2 or API keys.
Choose events like new contact or updated task and map data fields to your actions.
Run tests to verify data flow and enable your Zapier workflow for production.
Answer: The GHL Contacts API exposes endpoints to read contacts, tasks, notes, and appointments. With Zapier, you can set triggers and actions to automate these reads. Start with read-only access to explore data and then request broader permissions if needed.
Answer: No heavy coding is required. Use Zapier’s builder to configure connections, triggers, and actions. For more complex flows, a basic understanding of JSON and field mapping helps, but it’s not mandatory.
Answer: The endpoints include GET /contacts/:contactId, GET /contacts/, POST /contacts/, PUT /contacts/:contactId, and others for notes, tasks, and appointments. Use the docs to choose the right endpoints for your workflow.
Answer: Authentication is typically handled via OAuth2 or API keys. Ensure your connection has the correct scope (read or write) for the endpoints you intend to use.
Answer: Yes. You can create or update contacts (and related items) from Zapier by using the appropriate endpoints and proper authentication. Map fields to ensure data integrity.
Answer: Tasks and notes can be managed through the integration. Map fields so updates reflect across GHL and connected apps.
Answer: Endpoint documentation is available in the GHL API docs and within Zapier’s integration guide for the GHL Contacts API.
