Authenticate using OAuth 2.0 tokens with your GHL account and grant the requested scopes (including contacts.readonly). The Zapier connector will handle token refresh automatically.
In Zapier, authorize the GHL Contacts API connection through the on-screen OAuth flow or API key setup. This creates a secure, scoped connection between GHL and your Zapier workflows.
Key endpoints 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, and write endpoints: 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: A contact is created or updated in GHL, then bring core details into Zapier to drive downstream actions.
Actions: Create contact (POST /contacts/), Update contact (PUT /contacts/:contactId), Assign tags (POST /contacts/:contactId/tags).
Methods used: GET for reads, POST to create, PUT to update.
Key fields: contactId, email, firstName, lastName, phone.
Trigger: New or updated tasks tied to a contact appear in Zapier.
Actions: Create task (POST /contacts/:contactId/tasks), Update task (PUT /contacts/:contactId/tasks/:taskId), Complete task (PUT /contacts/:contactId/tasks/:taskId/completed), Delete task (DELETE /contacts/:contactId/tasks/:taskId).
Methods: POST, PUT, DELETE.
Key fields: contactId, taskId, title, dueDate, status.
Trigger: When a contact’s notes or appointments update, or business context changes.
Actions: List notes (GET /contacts/:contactId/notes), List appointments (GET /contacts/:contactId/appointments), List business context (GET /contacts/business/:businessId).
Methods: GET
Key fields: contactId, businessId, noteId, appointmentId.
Automate routine data sync between your CRM and apps without writing code.
Set up triggers and actions that scale with your team’s workflows.
Access the full endpoints suite to tailor automation to your use case.
Understand the core concepts behind GHL API access, authorization, endpoints, and how to build automations with Zapier.
An API is a set of rules that lets your software talk to GHL’s data and features securely.
A specific URL in the GHL API that performs an action or returns data.
An authorization framework that enables secure access to a user’s GHL data without sharing passwords.
A lightweight callback used to notify apps about events in GHL in near real time.
Automatically route new leads to the right owner and schedule follow-ups based on contact properties.
Create tasks from contact events and display status in a shared dashboard.
Aggregate notes and appointments into a daily digest for teammates.
Start by granting OAuth permissions for both systems and verify the scope (contacts.readonly) is enabled.
Map GHL endpoints to Zapier actions and set field-level mappings for contacts, tasks, notes, and tags.
Run end-to-end tests, then enable live automation and monitor logs for performance.
The GHL Contacts API exposes core data like contacts, tasks, notes, and appointments that you can access from Zapier to automate workflows. Using this connection you can build end-to-end automations without code, such as syncing new contacts to a marketing list or creating tasks from form submissions.
Available endpoints include reads like GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments, GET /contacts/, and GET /contacts/business/:businessId. Writes include 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, and POST /contacts/:contactId/tags.
No traditional coding is required. The Zapier App Connector provides a no-code interface to connect GHL endpoints. Some familiarity with APIs helps, but you’ll build workflows using triggers, actions, and mappings in a visual editor.
Authentication is handled via OAuth flows between GHL and Zapier. You authorize access using your GHL credentials. Zapier securely stores tokens and refreshes them automatically, with re-auth available from the connected accounts page.
Yes. You can create and update tasks, retrieve notes, and fetch appointments from Zapier. For two-way sync, pair triggers with appropriate actions to keep data in sync across systems.
Rate limits vary by endpoint and plan. Plan for retries and implement backoff in your workflows. If you hit a limit, stagger requests and cache data where possible.
Test using Zapier’s built-in test features for each trigger and action. Validate data mappings and ensure authentication works. Use a staging account to avoid affecting production data before going live.
Due to high volume, we will be upgrading our server soon!
