GHL requires secure authentication via OAuth 2.0 tokens or API keys. For this integration, the Zapier App Connector stores a connection with the scope ‘contacts.readonly’.
Zapier authenticates with GHL using OAuth 2.0 and securely stores credentials in the connection. No passwords are shared.
The Contacts API exposes endpoints to read and manage contacts, tasks, notes, and appointments. Below is a sample of the endpoints available for this integration.
Trigger: when a contact is updated in GHL, Zapier fetches the contact and related tasks, notes, and appointments to sync in your app.
Actions: update contact details in GHL, create or complete tasks, and attach notes from your app.
GET /contacts/:contactId plus subpaths like /contacts/:contactId/tasks, /contacts/:contactId/notes.
Key fields: contactId, name, email, phone, tags, status.
Trigger: a new contact created in your app prompts Zapier to POST /contacts/ to GHL.
Actions: POST /contacts/ to create, or PUT /contacts/:contactId to update existing contacts.
POST /contacts/; PUT /contacts/:contactId.
Key fields: name, email, businessId, phone.
Trigger: when a contact is updated, automatically create or update tasks via /contacts/:contactId/tasks.
Actions: POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, POST /contacts/:contactId/notes.
POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; POST /contacts/:contactId/notes.
Key fields: contactId, taskId, noteId, status, dueDate.
No-code setup lets you connect GHL and Zapier App Connector quickly without developers.
Automations run across systems with clicks, not code.
Reusable workflows and triggers scale with your business needs.
This glossary defines API terms you’ll see in this guide, including endpoints, triggers, actions, authentication, and data fields.
Application Programming Interface; a set of rules that enables two apps to communicate.
OAuth is a token-based authorization standard that lets apps access resources securely.
A specific URL in an API that performs a function and returns data.
A URL endpoint that notifies systems in real time when events occur.
Set up two-way data sync so updates in GHL reflect in your app instantly, and vice versa.
Create a templated sequence of tasks and notes when a new contact is added to streamline onboarding.
Push notifications to Slack or email when important fields change.
In Zapier, create a new connection to GHL’s Contacts API using OAuth 2.0 with the scope ‘contacts.readonly’.
Select triggers like ‘Contact Updated’ and actions like ‘Create/Update Contact’ to build your workflow.
Test end-to-end data flow, verify endpoint responses, and monitor logs before going live.
No coding is required to connect the GHL Contacts API with Zapier App Connector. The integration uses a standard OAuth 2.0 flow to authorize access and a no-code interface in Zapier to configure triggers and actions. You can select endpoints and map fields without writing code. The Contacts API in GHL provides read access to contacts, tasks, notes, and appointments so you can automate data movement with confidence.
The Contacts API exposes endpoints for reading and managing contacts, tasks, notes, and appointments such as GET /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/, PUT /contacts/:contactId, and more. In the Zapier App Connector you can configure these endpoints as triggers or actions to suit your workflow, including reading contact data and creating or updating tasks and notes.
Authentication is handled via OAuth 2.0 within the Zapier App Connector. When you connect, you grant Zapier access to the GHL Contacts API with the configured scope. Zapier securely stores tokens and uses them to authorize requests to GHL endpoints. No passwords are shared between systems.
With the default read-only scope for this integration (contacts.readonly), write operations to GHL are not permitted. If you need write access, you would adjust the scope accordingly in your OAuth configuration. In this setup, you can read contact data but cannot modify it from Zapier.
Read-only access means you can pull contact details, tasks status, notes, and appointments into your app for reporting or display. You cannot create, update, or delete records in GHL from Zapier unless a higher level of permissions is granted.
Test by creating a sample contact in GHL, then trigger the Zapier workflow to fetch the contact and related data. Validate that the data maps correctly in your app, check endpoint responses, and review the task logs in Zapier for any errors before going live.
If you run into issues, review the OAuth connection status in Zapier, confirm the scope permissions, and verify the endpoint URLs. For deeper help, consult the GHL API and Zapier App Connector documentation or contact support for assistance.
Due to high volume, we will be upgrading our server soon!
