Access the Contacts API by authenticating with OAuth credentials tied to your GHL account. Use the scope ‘contacts.readonly’ for reading data and ‘contacts.write’ where you need to create or modify records. Store credentials securely in Zapier and test the connection.
In Zapier, set up OAuth 2.0 for your App Connector integration. Provide the client ID and client secret from your GHL app, configure scopes, and authorize the app to access Contacts data. Run a test to confirm the connection.

Run test zaps to verify data flows, deploy automations, and set up monitoring alerts.
The GHL Contacts API is a RESTful interface that lets you read and manage contact data, including related tasks, notes, and appointments. In this integration, the Zapier App Connector serves as the bridge to connect your CRM data with other apps without writing code. This setup enables you to build no-code automations that move data between GHL and your favorite tools. Through the API, you can retrieve, create, update, and manage contacts and associated items while controlling access with OAuth-based authentication.
Yes. To use the API, you typically need a developer account or a GHL app registered in your developer console to obtain OAuth client credentials and define scopes. Zapier will use these credentials to obtain access tokens for API calls. Depending on your use case, you may request production access after initial testing. Keep your credentials secure and rotate them periodically according to best practices.
Commonly required scopes include contacts.readonly for reading data and contacts.write for creating or updating records. The exact scopes depend on the actions you plan to automate. Always apply the principle of least privilege: request only the scopes necessary for the workflow and avoid broad access unless required.
To test, use Zapier’s built-in connection test and a sample contact to verify data flows and field mappings. Validate responses from the endpoints and handle errors gracefully in your zaps. Monitor logs and retries to ensure reliability during real-world usage.
Yes. You can automate notes and tasks together by chaining actions in a single Zap: fetch a contact, create or update a note, and create or update tasks in sequence. This enables cohesive workflows where notes drive task follow-ups and reminders for teammates.
Resources include the GHL API documentation, Zapier App Connector docs, and community forums with examples and templates. Refer to the endpoint list and glossary within this guide for terminology and best practices.
