Authenticate using OAuth 2.0 or an API key, with the scope contacts.readonly to read contact data.
Set up a secure connection in the Zapier App Connector by storing the API key or OAuth token and testing the link to the Contacts API.

Build complex automations without writing code
Connect contacts, tasks, notes, and appointments across apps
Scale workflows with reusable Zapier templates
Key elements include endpoints, authentication, triggers, actions, and mapping fields across both systems
OAuth is an open standard for token based authorization that lets apps access user data without sharing passwords
A URL that performs a specific operation on a resource, such as retrieving a contact
Verification that a request comes from a trusted source, typically via OAuth tokens or API keys
The action performed on a resource in an API call, such as GET, POST, PUT, or DELETE
Trigger on new contact creation and auto create a follow up task for your team
Push changes from another system to Contacts API to keep records current
Aggregate notes from multiple contacts into a dashboard or sheet
Register the app, obtain client credentials, and set scopes such as contacts.readonly
Complete OAuth flow or supply an API key, then test the connection in Zapier
Configure triggers, actions, and filters to automate processes
The Contacts API supports multiple authentication methods including OAuth 2.0 and API keys. Choose the method that matches your security setup and workflow. In Zapier App Connector, use the connection to securely store these credentials. The platform will manage token refreshes and secure storage for you.
For syncing tasks and contacts, start with GET /contacts/:contactId to retrieve a contact and its tasks. Use GET /contacts/:contactId/tasks for task details and GET /contacts/:contactId/notes for notes. For listing multiple contacts, GET /contacts/business/:businessId provides a business scoped list, and you can paginate as needed.
In Zapier App Connector, run a Test Connection to verify authentication and basic data retrieval. Then create a sample Trigger to fetch new or updated data and test the Action steps with sample payloads. If anything fails, recheck credentials, scopes, and endpoint permissions.
The Contacts API enforces rate limits and supports pagination. If you hit limits, implement retries with backoff and paginate through results using page tokens. Always handle 429 responses gracefully in your workflow.
Yes, you can fetch notes and appointments for a contact using GET /contacts/:contactId/notes and GET /contacts/:contactId/appointments. Combine results in Zapier to drive actions or analytics. Notes and appointments can inform follow ups or scheduled tasks.
Map fields between GHL and Zapier by aligning the endpoint response fields with your Zapier data structure. Common mappings include contactId to id, name to fullName, and email to emailAddress. Use Zapier’s field mapping to handle nested data like tasks or notes.
Endpoint documentation is available in your API provider docs and within the Zapier app’s connector reference. Start with the Contacts API endpoints and example requests, then explore authentication samples. For deeper examples, check curl snippets and sandbox credentials.
Due to high volume, we will be upgrading our server soon!
