To access the Contacts API you will configure OAuth 2.0 credentials or an API key in your GHL developer settings, then securely store the token in Zapier App Connector for each connection.
Zapier authenticates with GHL using OAuth 2.0 or API keys, giving scoped access to read contacts, their tasks, notes, and related data.
GET /contacts/:contactId – Retrieve a single contact; GET /contacts/:contactId/tasks – List tasks for a contact; GET /contacts/:contactId/tasks/:taskId – Retrieve a specific task; GET /contacts/:contactId/notes – List notes for a contact; GET /contacts/:contactId/notes/:id – Retrieve a note; GET /contacts/:contactId/appointments – List appointments for a contact; GET /contacts/ – List contacts; GET /contacts/business/:businessId – List contacts for a business; POST /contacts/ – Create a new contact; PUT /contacts/:contactId – Update a contact; DELETE /contacts/:contactId – Delete a contact; POST /contacts/:contactId/tasks – Create a task; PUT /contacts/:contactId/tasks/:taskId – Update a task; PUT /contacts/:contactId/tasks/:taskId/completed – Mark a task as completed; DELETE /contacts/:contactId/tasks/:taskId – Delete a task; POST /contacts/:contactId/tags – Add tags to a contact
Trigger a workflow whenever a contact is created or updated in GHL, pushing changes to connected apps via Zapier.
Actions include creating or updating tasks, notes, or tags in response to the trigger.
Method path: Use GET to fetch records and POST/PUT to push updates to target apps via Zapier actions.
Key fields: contactId, updatedAt, status.
Trigger to sync changes across CRM, calendar, and notes when contact data changes.
Actions: create/update appointments, sync notes, update contact properties.
Method path: PUT /contacts/:contactId to update and POST /contacts/:contactId/notes to append notes.
Key fields: contactId.
Trigger to refresh related data when a contact changes.
Actions: update tags, sync appointments, and refresh related entities in connected apps.
Method path: GET /contacts/:contactId and PUT /contacts/:contactId to sync data.
Key fields: contactId.
Benefit 1: Build powerful automations without writing code.
Benefit 2: Eliminate manual data entry and reduce errors.
Benefit 3: Accelerate onboarding and client management with real-time data flows.
Below are core terms and processes to help you understand how the GHL Contacts API and the Zapier App Connector work together.
A specific URL in the GHL API used to perform an action, such as retrieving a contact or creating a task.
The process of verifying identity and granting access to the GHL API, typically via OAuth 2.0 tokens or API keys.
A standard protocol for authorization that enables secure access to user data without sharing passwords.
Automations built using tools like Zapier that connect apps without writing code.
Set up a Zapier workflow to automatically create a task when a contact is created or updated in GHL.
Push new contact notes to your documentation system or CRM notes.
Mirror GHL appointments into calendar apps to keep schedules aligned.
Configure OAuth or API keys in the Zapier app to authorize access to GHL.
Select the Contacts API endpoints you want to use, such as retrieving contacts or creating tasks.
Create Zapier workflows to automate data flow between GHL and your apps.
The Contacts API lets you read and manage contact data within GHL from external tools. Using the Zapier App Connector, you can pull contact details, tasks, notes, and appointments into your automation workflows. This enables seamless data movement and event-driven actions across your stack. To get started, authenticate your connection, select the endpoints you need, and begin building Zaps that respond to contact changes.
Zapier App Connector supports OAuth 2.0 and API key based authentication to connect to GHL. You will configure credentials in your app settings and store tokens securely in Zapier. This ensures read-only access for most workflows unless you request additional scopes. Always follow least-privilege practices.
Available endpoints cover retrieving and updating contacts, managing tasks, notes, appointments, and tags. You can fetch a contact by ID, list a contact’s tasks or notes, create tasks, and update a contact’s properties. The full endpoint set enables building comprehensive automations without leaving your workflow.
Yes. You can create new tasks, update existing tasks, and mark them as completed directly from Zapier. This allows you to drive work-item changes in GHL based on events in your connected apps. Always validate required fields when creating or updating tasks.
Test connections by creating a test Zap in Zapier that performs a simple read or write action against a contact. Check authentication scopes, verify data mapping, and confirm that changes appear in GHL as expected. Use sandbox or test data when possible.
There are standard API rate limits governed by GHL. If your workflows exceed limits, you may experience throttling. To avoid this, batch requests, stagger polling, or implement exponential backoff in your Zaps. Monitor usage in your app settings.
Absolutely. You can connect the Contacts API to multiple apps via Zapier App Connector and orchestrate cross-app automations. Design workflows that pull data from GHL into your CRM, calendar, or knowledge base, and vice versa, with appropriate triggers and actions.
Due to high volume, we will be upgrading our server soon!
