Authenticate requests to the Contacts API via Zapier App Connector using OAuth 2.0 or API keys. Zapier securely stores credentials and manages token refresh automatically.
Connect your Zapier account to the Contacts API app using OAuth or API keys to enable actions and triggers, with secure credential handling.

Automate repetitive CRM tasks without writing code, saving time and reducing errors.
Centralize data flow between Contacts API and other apps for consistent info across tools.
Scale automation as your business grows with flexible triggers and actions.
This glossary covers API endpoints, authentication, data synchronization, and common workflow terminology used when integrating the Contacts API with the Zapier App Connector.
A specific URL path and HTTP method used to perform an action (read, create, update, delete) against an API.
The process of verifying identity and granting access to API resources, typically via OAuth tokens or API keys.
A secret value used to authenticate API requests, often issued per app or user.
A user-defined HTTP callback that triggers when a specific event occurs in a service, enabling real-time data flow.
Automatically create or update a contact in Contacts API when a form submission occurs, with field-mapping and validation.
Create or update tasks in Contacts API from project management or support apps to keep teams aligned.
Append notes to Contacts API records when tickets update, giving agents quick context in one place.
In Zapier, locate the Contacts API app and click Connect to authorize data flow from your GHL account.
Map fields between Contacts API and your trigger/action, select endpoints, and test the connection.
Turn on the Zap to begin automatic synchronization between your apps and Contacts API.
The Contacts API integration with Zapier App Connector enables you to read and write contact data, create tasks and notes, and attach appointments, all within your automation workflows. This empowers you to build end-to-end processes without custom coding. Two-way data flow is supported so updates in one system propagate to the other as actions run.
Available endpoints cover common CRM needs: reading a contact (GET /contacts/:contactId), listing tasks (GET /contacts/:contactId/tasks), retrieving notes (GET /contacts/:contactId/notes), and more. For writes, you can create contacts (POST /contacts/), update (PUT /contacts/:contactId), and manage tasks (POST/PUT/DELETE on /contacts/:contactId/tasks/:taskId) and tags.
Authentication is handled via OAuth 2.0 or API keys. Zapier securely stores credentials and prompts for re-authentication when needed. Follow the app’s guided setup to link your GHL Contacts API and start making authenticated requests.
Yes. You can trigger automations from contact changes, task updates, and note additions. Actions can then create, update, or fetch related data to keep all connected apps in sync.
Test connections directly in Zapier during setup. Use sample data or sandbox environments when available to verify responses, field mappings, and error handling before going live.
Rate limits and quotas depend on your API plan. Refer to the Contacts API docs for current limits and contact support if you anticipate higher throughput or specialized usage.
Due to high volume, we will be upgrading our server soon!
