Use OAuth 2.0 with the scope ‘contacts.readonly’ to securely access contact data. Register your app, obtain an access token, and refresh tokens as needed.
Create a new connection in Zapier, supply the credentials from your GHL OAuth app, and test the connection before building automations.
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; 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 to pull the latest details into your workflow.
Actions: fetch contact details, create or update notes, attach tasks, or tag the contact in Zapier.
GET /contacts/:contactId
Key fields: contactId, firstName, lastName, email, phone
Trigger: when a contact’s tasks are updated or a new task is created
Actions: create or update tasks, log related notes, and update contact activity
GET /contacts/:contactId/tasks
Key fields: contactId, taskId, taskName, status, dueDate
Trigger: new contact along with related tasks appears in GHL
Actions: synchronize contact data, create/update tasks, and attach notes in your target app
GET /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId, summary, notes, lastUpdated
Automate complex workflows without writing code using drag-and-drop actions.
Prototype automations quickly and iterate with live data from GHL endpoints.
Keep data synchronized in real time across your apps and teams.
This glossary explains OAuth 2.0, API endpoints, triggers, actions, scopes, and data mapping as used for the GHL Contacts API and the Zapier App Connector.
OAuth 2.0 is an authorization framework that issues access tokens to securely access API resources without exposing user credentials.
An API endpoint is a specific URL path that performs a defined operation, such as GET /contacts/:contactId.
Scopes define access levels, like ‘contacts.readonly’, requested during OAuth.
Webhooks are callbacks that notify your app of events in real time.
Capture lead source data from GHL and tag or route contacts in your CRM via Zapier when a new contact is created.
Create tasks from contact notes when due dates approach to keep follow-ups timely.
Automatically move or tag inactive contacts for cleanup based on activity in GHL.
In GHL, create an OAuth client and copy the client ID and secret to configure in Zapier.
Add a new connection in Zapier, select the Contacts API integration, paste credentials, and run a test.
Choose a trigger such as contact created, then add actions to update your CRM, notes, or tasks.
The GHL Contacts API exposes endpoints to read and manage contact data, tasks, notes, and more. Use OAuth 2.0 tokens with the contacts.readonly scope to access data via Zapier. Start by creating a GHL OAuth app and obtaining client credentials, then configure the Zapier App Connector connection. You can trigger workflows on contact events and perform actions such as creating tasks or updating notes.
Zapier App Connector requires a registered GHL OAuth client and a configured connection in Zapier. You will provide the client ID and secret, authorize in GHL, and test the connection. After successful authentication, you can build automations against the available endpoints.
The integration supports endpoints for accessing contacts, their tasks, notes, and appointments, along with endpoints to create or update contacts and tasks. See the endpoint list above for the full set.
Yes. Zapier lets you test triggers and actions using sample data before you enable live tasks. Use a sandbox or test mode where available.
Latency depends on API response times and your Zapier plan. In practice, you’ll see near real-time updates for most workflows.
Rate limits apply per API plan. If you hit limits, you can rate-limit requests or stagger tasks in your Zapier automation.
You can view task histories, error messages, and execution logs in Zapier’s task history and in GHL’s API activity logs if enabled.
Due to high volume, we will be upgrading our server soon!
