Access to the Contacts API requires proper authentication and the correct scope (contacts.readonly). Use OAuth 2.0 tokens issued for your GHL account to securely call endpoints.
Zapier App Connector uses OAuth or API key methods to authorize connections. Configure the connected account with the appropriate credentials and scopes to access Contacts API data.
The integration leverages these endpoints: Endpoint9: contacts.write, Endpoint10: POST /contacts/, 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, 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 specific contact is retrieved by ID to populate downstream workflows.
Actions include pulling contact fields, recent tasks, notes, and appointments to drive automated processes.
GET /contacts/:contactId
contactId, include, fields to return
Trigger on-demand retrieval of a contact’s task list for project tracking.
Actions map task properties (title, due date, status) to Zapier steps and downstream actions.
GET /contacts/:contactId/tasks
contactId, task fields, status
Trigger when a contact’s notes are requested to augment records and history.
Actions copy note content, date, and author into your workflow notes or CRM records.
GET /contacts/:contactId/notes
contactId, noteId, fields to return
Build powerful automations quickly without writing code by mapping GHL data to Zapier steps.
Automate data sync across contacts, tasks, notes, and appointments to save time and reduce errors.
Easily extend workflows with conditional logic and multi-step actions in Zapier.
Understand the core elements and processes involved in connecting the Contacts API to the Zapier App Connector, including authentication, endpoints, data mapping, and workflow triggers.
An API is a set of rules that enables two software systems to communicate; the GHL API exposes endpoints like GET /contacts/:contactId for integrations.
OAuth 2.0 is the authorization framework used to grant secure access tokens for API calls to GHL resources.
An endpoint is a specific URL in an API that performs an action, such as retrieving a contact or updating a task.
REST is an architectural style for designing networked applications using standard HTTP methods like GET, POST, PUT, and DELETE.
Capture new or updated contacts from forms and automatically sync essential fields to GHL via the Contacts API.
Create or update tasks and notes in GHL when events occur in your connected apps to keep records current.
Use endpoint data to categorize contacts and trigger targeted campaigns in GHL through Zapier.
In GHL, create a new API integration and obtain client credentials to authorize the Zapier App Connector.
Set up OAuth 2.0 flow and request the required scope: contacts.readonly to read contact data.
Test the connection in Zapier, then map GHL contact fields to Zapier fields and set up your first workflow.
The Contacts API is a set of endpoints provided by GHL that allows you to read and manage contact data, tasks, notes, and more. It enables external apps like Zapier App Connector to interact with your GHL data. This page focuses on the specific integration between the Contacts API and the Zapier App Connector.
No-code integration is possible with Zapier App Connector. You can connect the Contacts API to Zapier and build automations by selecting triggers, actions, and data mappings without writing code. Some advanced scenarios may require scripting, but for most workflows, no coding is needed.
You can access contacts, their tasks, notes, appointments, and related business data. The API endpoints cover reading and modifying these resources, depending on the endpoint and your permissions.
OAuth 2.0 authentication is used to securely authorize API calls. You’ll exchange client credentials for access tokens and refresh tokens, then use the access token in API requests to the Contacts API.
Rate limits depend on your GHL plan. In practice, typical usage patterns stay well within quotas for standard automation tasks. If you anticipate higher volume, consider batching requests or upgrading your plan.
Yes. The API supports creating, updating, and deleting contacts, tasks, and other related resources, subject to permissions and scope in your OAuth token.
API documentation, SDKs, and examples are available in the GHL developer portal. You can find endpoint references, sample requests, and error handling guidance there.
Due to high volume, we will be upgrading our server soon!
