Use OAuth 2.0 with access tokens and automatic token refresh. Keep credentials secure and rotate them periodically.
Zapier App Connector authenticates with the GHL Contacts API using OAuth 2.0 or API keys. Store credentials securely in Zapier and test the connection from the app configuration.

This glossary covers Contacts Tasks Notes Appointments and the main API endpoints used to connect GHL to Zapier App Connector
A person stored in the Contacts API with fields like name email phone and custom tags
A task assigned to a contact to track follow ups and activities
A free form text note attached to a contact for context or history
Scheduled meeting or call linked to a contact and included in calendar integrations
Trigger updates when a contact changes stage create tasks for follow ups and sync notes
Onboard new leads by creating a contact scheduling an intro call and tagging the record
When a support ticket is opened log a note create a task for follow up and notify the team
Obtain your OAuth token or API key from the Contacts API dashboard and configure OAuth in Zapier
Use the test connection to validate access to contacts tasks and notes
Choose contact fields to sync and set up triggers and actions in Zapier
The Contacts API is the layer that exposes contact data including names emails phones and notes. It enables reading updating and linking related resources like tasks and appointments. This API is the bridge between GHL data and automation tools like Zapier.
OAuth 2.0 is supported for secure access with tokens that can be refreshed automatically. API keys can be used as an alternative where supported. Keep credentials private and rotate them regularly.
Yes. You can trigger actions when a contact is created updated or when related resources like tasks notes or appointments change. This enables real time automations in Zapier.
End points for syncing typically include retrieving contact records listing tasks notes and appointments. Use POST for creates PUT for updates and DELETE for removals to keep data in sync across apps.
No code is required to connect the Contacts API with the Zapier App Connector. The integration is designed for no code workflow automations using triggers actions and data mapping.
To test your connection use Zapier test actions and check the returned payloads. Ensure scopes like contacts.readonly align with the endpoints you use and verify tokens refresh works as expected.
Rate limits vary by plan. Check the API docs for the current quotas and backoff rules. If you approach limits, consider batching requests or staggering triggers.
Due to high volume, we will be upgrading our server soon!
