Use OAuth 2.0 to authorize access to the GHL Contacts API via the Zapier App Connector. Request the required scope (contacts.readonly) to read data, and upgrade to write access if you need to create or update records.
In Zapier, create a new connection for the GHL Contacts integration and authorize with your GHL account using OAuth 2.0. This connection securely handles tokens and refreshes automatically.
Key endpoints include: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/tasks/:taskId, GET /contacts/:contactId/notes, GET /contacts/:contactId/notes/:id, GET /contacts/:contactId/appointments, GET /contacts/, GET /contacts/business/:businessId, contacts.write, POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, DELETE /contacts/:contactId/tasks/:taskId, POST /contacts/:contactId/tags
Trigger: New or updated contact in GHL to start a Zap in Zapier
Actions: Create or update a contact, attach notes, and assign related tasks from Zapier
Example paths: GET /contacts/:contactId to fetch details
Key fields to map: contactId, name, email, phone, company, tags
Trigger: On-demand fetch of a single contact or contacts list
Actions: Retrieve contact details, pull related tasks and notes
GET /contacts/:contactId
Key fields: contactId, name, email
Trigger: When a new contact is created in Zapier
Actions: Create a new contact or update an existing one; optionally add tasks, notes, and tags
POST /contacts/ to create, PUT /contacts/:contactId to update
Key fields: name, email, phone

This glossary defines API terms used in this integration guide, plus the data flows and processes you’ll implement
Definition: A specific URL path in an API that performs a function or returns data
Definition: A standardized authorization framework that grants access tokens without sharing user credentials
Definition: A mechanism for apps to receive real-time data by sending HTTP POST requests when events occur
Definition: The maximum number of API calls allowed in a given time window
Description: Capture form leads and automatically create or update GHL contacts, then trigger follow-up actions in Zapier
Description: When a task is completed in GHL, push a note to the related contact in Zapier
Description: Apply dynamic tags to contacts based on form source, campaign, or region
Description: In Zapier, choose Connect GHL, authorize the account, and pick the Contacts API scope
Description: Map contact fields (name, email, phone) to Zapier fields and select endpoints for your workflow
Description: Run test zaps, verify data integrity, and deploy automation to production
You can read contact data, tasks, notes, and appointments through the GHL Contacts API. The scope for this guide centers on read access with the option to upgrade to write permissions as needed. Ensure your OAuth token has the proper scopes before attempting operations.
No coding is required for basic use—Zapier provides a visual editor to create zaps, map fields, and define triggers. For advanced workflows, you can extend with multi-step actions and filters.
OAuth 2.0 is supported. You authorize access in Zapier by linking your GHL account and granting the requested scopes. Tokens refresh automatically, keeping connections secure.
Read operations use GET endpoints like GET /contacts/:contactId. Write operations use POST, PUT, or DELETE endpoints such as POST /contacts/ and PUT /contacts/:contactId. Check the API docs for full details.
Yes. You can create new contacts and attach tasks or notes via actions in Zapier. Use POST /contacts/ and related endpoints to build richer workflows.
Rate limits depend on your GHL plan and the API tier. Plan for handling retries and backoff in Zapier to avoid hitting limits.
Field mapping is done in Zapier’s editor. Map GHL fields (name, email, phone) to Zapier fields, and use transformers if needed to format data.
Due to high volume, we will be upgrading our server soon!
