Use OAuth 2.0 with the Contacts API and grant the Zapier App Connector the contacts.readonly scope to securely access contact data, tasks, and related resources.
Set up a secure connection in Zapier: initialize OAuth credentials for the App Connector, authorize access, and monitor token renewals to keep integrations alive.

This glossary defines important terms and core processes used when integrating GHL’s Contacts API with the Zapier App Connector, including authentication, endpoints, and data fields.
Application Programming Interface: a set of rules and endpoints that allow applications to communicate and exchange data.
OAuth 2.0 is the standard authorization protocol used to grant secure access tokens for API connections.
A URL path identifying a resource on an API server that you can query or update.
The granted permissions for an access token, such as read or write access to specific resources.
Use triggers to route new contacts to the right owner based on company, location, or score, then create tasks and notes automatically.
Automatically create tasks for follow-ups when a contact is updated, with due dates and reminders.
Pull notes from GHL and attach concise summaries or tags to contacts in Zapier automations.
Create a new connection in Zapier and authorize using OAuth 2.0 with the Contacts API scope set.
Choose endpoints, map contact fields, and set up triggers and actions in Zapier.
Run end-to-end tests, verify data flow, and roll out automation to production.
You can access core contact fields, tasks, notes, appointments, and related data depending on permissions. The current integration scope is contacts.readonly, which allows reading contact information but does not permit direct data modification through this connector. For write operations, you would need elevated permissions and corresponding API scopes. Always verify your token scopes before attempting actions that modify data.
No heavy coding is required. Use Zapier triggers and actions to automate workflows between GHL Contacts API and your apps. Some field mapping and test runs help ensure data flows correctly, but the setup is designed to be no-code friendly.
Authentication is performed via OAuth 2.0. You’ll authorize the Zapier App Connector to access your GHL data with a defined scope (for example, contacts.readonly). Tokens may expire and require refresh, so monitor token lifecycle within Zapier.
Handle errors using Zapier’s built-in retry logic and status checks. Implement robust error handling by mapping API error responses, respecting rate limits, and configuring retries or backoffs where supported.
The endpoints cover common CRM actions, including retrieving contacts, tasks, notes, and appointments; creating and updating contacts; and managing tasks and tags. Review the endpoint list to identify which operations fit your workflow. Note that write endpoints require appropriate permissions.
Data can be near real-time for triggers, with configurable intervals for scheduled syncs. The exact frequency depends on how you design your Zapier workflows and how often the connected apps poll for updates.
Yes. The integration is built to support no-code automation via Zapier, so you can create complex workflows without writing code. For advanced scenarios, some light field mapping and logic in Zapier may be helpful.
Due to high volume, we will be upgrading our server soon!
