Authenticate to the Contacts API using OAuth 2.0 to obtain a short‑lived access token with the configured scope (e.g., contacts.readonly).
Configure OAuth 2.0 or API key authentication for the Zapier App Connector so your automations can securely call the GHL Contacts API.
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 GET /contacts/ – List all contacts GET /contacts/business/:businessId – List contacts for a business POST /contacts/ – Create a contact PUT /contacts/:contactId – Update a contact DELETE /contacts/:contactId – Delete a contact POST /contacts/:contactId/tasks – Create a task for a contact 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 – Tag a contact

Centralize contact data across apps and automate processes without writing code.
Leverage endpoints for tasks, notes, and appointments to build end-to-end workflows.
Scale securely with token-based authentication and granular scopes like contacts.readonly.
This glossary explains core concepts and how they apply to integrating the Contacts API with the Zapier App Connector.
Application Programming Interface: a set of endpoints and methods to access data and trigger actions in a service.
A specific URL path and HTTP method used to perform a particular operation in the API.
The process of proving identity and obtaining an access token to call protected API endpoints.
A permission set that defines what actions are allowed by the access token (e.g., contacts.readonly).
Automatically create a contact in your CRM when a new lead is captured in a form, then kick off tasks and notes.
Attach notes to contacts based on activity and trigger reminders.
Create, update, and complete tasks across apps as contacts move through stages.
Obtain OAuth credentials and authorize access to the Contacts API.
Choose the endpoints you need (read-only) and set the proper scope (contacts.readonly).
Test connections, create an initial workflow, and enable automation.
The scope controls where and how you can access data. For read-only access use scopes like contacts.readonly. You can combine scopes as needed.
The endpoints listed include GET /contacts/:contactId, GET /contacts/, POST /contacts/, and related sub-resources for tasks, notes, and appointments. Use the ones that align with your automation goals.
Authentication uses OAuth 2.0 with access tokens. Rotate tokens and store securely to prevent unauthorized access.
Yes. Use a sandbox or test mode in the Zapier App Connector to validate your setup before deploying to production.
No custom coding is required for common automations. The connectors provide triggers and actions for the endpoints.
You can access core contact data, including tasks, notes, appointments, and tags, depending on granted scopes and endpoints used.
Rate limits depend on your GHL API plan. Refer to the developer portal or your account for exact quotas and throttling rules.
Due to high volume, we will be upgrading our server soon!
