Access requires an OAuth token with the appropriate scope (for example, contacts.readonly). Include the token in the Authorization header as Bearer YOUR_TOKEN when calling any endpoint.
Zapier uses OAuth 2.0 to connect to GHL. In the Zapier app console, create or select your GHL connection and grant the Contacts API permissions requested by your Zap.

Trigger: a new or updated contact is created in GHL.
Actions: fetch full contact profile, update CRM fields, and push related notes or tasks to connected apps.
GET /contacts/:contactId
Key fields: contactId, name, email, phone
Trigger: task events for a contact (created, updated, or completed).
Actions: create or update tasks in your PM tool, reflect status, and notify teams.
POST /contacts/:contactId/tasks
Key fields: contactId, taskId, title, dueDate
Trigger: a note is added or updated for a contact.
Actions: create notes, apply or adjust tags for segmentation, and sync to related apps.
POST /contacts/:contactId/notes
Key fields: contactId, noteId, content
Automate routine data tasks without writing code.
Speed up workflows with triggers, actions, and data mapping.
Scale operations by centralizing contact data across tools.
This glossary defines API, OAuth, endpoints, triggers, actions, and data fields you’ll encounter when linking GHL Contacts API with Zapier App Connector.
An API is a set of rules and protocols that allows software applications to communicate and share data.
An authorization framework that enables secure access to user data without sharing credentials; used for secure integrations with GHL.
A real-time HTTP callback that notifies your app when a specific event occurs in another service.
Constraints on how many API requests you can make in a given window to prevent abuse.
Create a Zap that sends a real-time alert to your team when a new contact is created in GHL.
Automatically mirror new or updated tasks from GHL into your project management app to keep everyone aligned.
Auto-apply tags to contacts based on criteria and route them into targeted campaigns.
Open Zapier App Connector, select the Contacts API, and authorize access to your GHL account.
Choose a trigger (e.g., new contact), choose an action (e.g., create/update in another app), and map fields.
Run a test, verify data accuracy, and activate the Zap for automation.
The Contacts API is the gateway to programmatic access to your GHL contact data. It lets you read, create, update, and delete contacts, and access related resources like tasks and notes. In Zapier, you can trigger on contact events and perform actions in connected apps without code, making automation simple and scalable.
Authentication uses OAuth 2.0; you must authorize and grant the requested scopes to access the Contacts API. Store tokens securely and refresh them as needed. Always use the Bearer token in the Authorization header when calling endpoints.
Available endpoints include GET /contacts/:contactId, POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, and related resources like tasks and notes. You can map fields between GHL and your apps to drive automation in Zapier.
Yes. You can create or update contacts using POST and PUT endpoints, provided your OAuth token has the necessary scopes. Use proper field mappings to ensure data integrity across tools.
Notes and tasks can be created and associated with a contact using dedicated endpoints. Use triggers to propagate changes to connected apps and maintain consistency across your workflows.
Rate limits depend on your GHL plan and API usage; monitor response headers for usage. If you approach quotas, stagger requests or batch updates to maintain reliability.
Sample workflows and templates are available in the Zapier App Connector documentation. Copy these templates and customize mappings and triggers to fit your data and processes.
Due to high volume, we will be upgrading our server soon!
