Access to the Contacts API requires a secure OAuth flow or an API token. Use your GHL developer credentials to request access, then exchange the authorization for a valid access token to call endpoints such as GET /contacts/:contactId.
In the Zapier App Connector, authorize your GHL connection once and reuse the connection for all API calls. Store tokens securely and refresh as needed.

Build automation without writing code to manage contacts, tasks, and notes.
Create multi-step workflows that update records and trigger follow-up actions automatically.
Centralize data flow between GHL and other apps using a visual Zapier builder.
Understand the core elements: contacts, tasks, notes, appointments, endpoints, authentication, and data fields that power the integration.
A contact represents a person or organization stored in your GHL Contacts; used to associate tasks, notes, and activities.
An API endpoint is a specific URL path that performs a defined operation (retrieve, create, update) on a resource.
A task is a to-do item linked to a contact; it can be created, updated, or marked as completed.
A note is a text entry linked to a contact to record information or context.
Capture new leads from forms and automatically create onboarding tasks for your team.
Apply campaign tags to contacts as they move through your funnel and trigger related actions.
Generate a compiled report of contacts, tasks, notes, and upcoming appointments for leadership review.
In Zapier, choose Connect to GHL, grant access, and select Contacts API scope.
Map fields between Contacts API and Zapier fields (contactId, name, email, etc.).
Run a test, verify data flow, and enable the zap for production.
The Contacts API lets you read and write contact data, along with related tasks, notes, and appointments. Use it to automate CRM workflows from form submissions to onboarding. This guide covers authorization, endpoints, and practical examples. Explore how to retrieve and update contact data, manage tasks, and attach notes to keep your team aligned.
Authenticate using OAuth 2.0 or an API key issued by your GHL account. In the Zapier App Connector, connect the GHL app once and reuse the connection for subsequent calls. Be mindful of rate limits and scopes.
Endpoints include retrieving contacts, listing tasks and notes, creating and updating contacts, and tagging. This page outlines the core endpoints and typical use cases.
Yes. The Zapier App Connector provides no-code triggers and actions to connect GHL data with hundreds of apps. You can automate workflows without writing code.
If you see authentication errors or missing data, re-auth the GHL connection, verify the access token, and confirm the requested scope matches your needs. Check endpoint paths and ID values.
Typically you need read or write permissions for contacts, tasks, notes, and tags depending on the actions you want to perform. Ensure your token has the necessary scopes.
Look for example workflows in the Zapier App Connector gallery and consult the API reference for common patterns such as contact creation, task updates, and note tagging.
Due to high volume, we will be upgrading our server soon!
