Access to the Contacts API is controlled via API tokens and OAuth. Ensure your token has at least read access for this integration.
Zapier handles app authentication securely using OAuth 2.0 flows or API keys, depending on the connector. Set up the connection in your Zapier dashboard.
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: A contact is updated or retrieved. Action: Fetch contact details and related notes/tasks.
Actions: pull contact details, fetch associated tasks and notes, then route data to other apps via Zapier.
GET /contacts/:contactId
contactId, fields: id, name, email, phone, lastModified
Trigger: Task changes in your workflow. Action: Update specific tasks on a contact.
Actions: create or update tasks, set status or completion, and sync back to GHL.
PUT /contacts/:contactId/tasks/:taskId
contactId, taskId, status, dueDate, completed
Trigger: New note added for a contact. Action: Create or fetch notes for the contact.
Actions: post notes to /contacts/:contactId/notes or retrieve existing notes to attach to workflows.
POST /contacts/:contactId/notes
contactId, noteId, content, createdAt
Automate workflows without writing code, linking Contacts API data to dozens of apps in minutes.
Keep contact data in sync across systems with reliable triggers and actions.
Prototype, test, and deploy new automations quickly using ready-made endpoints.
This glossary defines common terms used in this guide: APIs, endpoints, authentication, triggers, actions and data mapping.
An API is a set of rules that lets software applications communicate with each other.
OAuth 2.0 is a secure authorization framework that lets apps access data without sharing passwords.
An endpoint is a specific URL in an API that performs a function, such as retrieving a contact.
A webhook is a real-time HTTP callback that notifies another app when an event occurs.
Capture leads from forms and automatically create contact records in the Contacts API via Zapier.
Turn survey answers into actionable tasks assigned to teams, with status updates back to the Contacts API.
Append notes to a contact’s history when a survey is completed, accessible across apps.
In Zapier, authorize the Zapier App Connector to access the Contacts API using OAuth 2.0 or an API key.
Choose endpoints like GET /contacts/:contactId, POST /contacts/, and map fields to your workflow.
Run tests to verify data flow, then deploy the zap to production for ongoing automation.
The Contacts API lets you retrieve and manage contact data, tasks, notes and more within GHL. This enables you to automate workflows and keep systems in sync. Use read operations to pull data for dashboards and triggers.
No heavy coding is required. The Zapier App Connector provides a no-code interface to configure triggers and actions against the Contacts API. For advanced scenarios, you can extend with custom fields and mappings.
Key endpoints include retrieving a contact, listing tasks, notes and appointments, creating and updating contacts and tasks, and adding notes. The guide highlights the most useful paths for typical workflows.
You can both read and write depending on the connected token scope. For example, read access lets you pull data, while write access allows creating or updating contacts and tasks.
Authentication is handled via OAuth 2.0 in the Zapier App Connector or via API keys where supported. Set up the connection in your Zapier account and grant the requested permissions.
Map fields consistently across apps, use clear naming, and validate data types. Test end-to-end data flows and handle nulls gracefully to avoid broken automations.
Refer to the Contacts API docs and the Zapier App Connector docs for deeper guidance, samples, and SDKs. Communities and support channels are available if you need help.
Due to high volume, we will be upgrading our server soon!
