Authenticate requests to the Contacts API within Zapier using OAuth or API keys, with scope set to readonly to protect data.
In Zapier, configure OAuth or API keys for authenticating with GHL, then test the connection to ensure secure API access.

Definitions of API, endpoints, authentication, webhooks, and data flows used to connect GHL with the Zapier App Connector
A set of rules and endpoints that lets apps talk to GHL and pull or push data, such as contacts, tasks, and notes.
A notification call from GHL to another app when a specified event occurs, enabling real-time updates.
A secure authorization flow used to grant access to the GHL API without sharing passwords.
A specific URL path in the API that performs an action or returns data.
Pull contact data from GHL and enrich in your CRM or marketing platform using downstream apps.
Coordinate tasks, notes, and appointments across systems on trigger events.
Set up reminders and follow-ups based on contact activity and appointments in GHL.
Create or select the GHL app in Zapier and obtain client credentials.
Set the scope to contacts.readonly and ensure appropriate access.
Run tests with sample data and deploy your Zapier workflow.
The GHL Contacts API exposes endpoints to read and write contact data, tasks, notes, and appointments. You can access it via Zapier App Connector by configuring OAuth or API keys and selecting the contacts.readonly scope for read-only access. Start with the basic GET endpoints to surface contact information, then expand to related resources as needed.
No code is required for basic automations. Zapier provides a graphical interface to map endpoints to triggers and actions. For advanced flows, you can use code steps or custom webhooks if needed.
Permissions depend on your GHL plan and the scope granted. readonly allows viewing data, while write permissions enable updates like creating tasks or notes. Always follow least privilege and rotate credentials regularly.
Use OAuth where possible; store tokens securely and use refresh tokens. In Zapier, test the connection and ensure scopes match required access.
Yes. You can fetch appointments and business data via dedicated endpoints, then connect them to your calendars, CRM, or BI tools.
If an endpoint returns an error, review the HTTP status code, verify authentication, validate required fields, and retry with correct parameters. Implement robust error handling in your Zap.
See the official GHL API documentation or the Zapier app connector docs for example requests, sample responses, and API reference.
Due to high volume, we will be upgrading our server soon!
