Access to the Contacts API is secured via OAuth 2.0 and API keys. Store tokens securely, rotate credentials regularly, and apply least-privilege scopes (readonly for retrieval, write for updates).
In Zapier, configure OAuth credentials and store access tokens to securely call GHL endpoints. Use the requested scopes to read and write contact data.

Automate repetitive processes without writing code
Faster onboarding and scalable integrations across teams
A unified flow for contacts, notes, tasks, and appointments
Understand the elements you’ll work with: endpoints, triggers, actions, and data fields used by the GHL Contacts API and the Zapier App Connector.
An Application Programming Interface that lets applications talk to each other using defined endpoints and data formats.
A specific URL path that performs a particular operation in an API.
Authorization framework used to securely grant access tokens to APIs without sharing passwords.
A secure string that represents the right to access an API, typically used in requests.
Auto-create contacts and assign welcome tasks when a new signup is captured in GHL.
Push support ticket notes into the contact timeline via Zapier.
Send a daily digest of tasks and appointments to teams.
Generate an API key and OAuth client for Zapier in the GHL developer settings.
Connect the app in Zapier and grant the requested scopes for contacts.readonly and.contacts.write.
Define field mappings for contacts, tasks, and notes and run a test run.
The GHL Contacts API lets you read and manage contacts, tasks, notes, and appointments. It is designed for no-code or low-code integrations through the Zapier App Connector, while also supporting custom automation through API calls. You’ll typically start with authentication and scope setup, then call endpoints to fetch or modify contact data.\nKey benefit: you can automate everyday CRM workflows without writing server-side code, using triggers and actions in Zapier paired with GHL data.
Authentication is done via OAuth 2.0 and API keys. In your GHL account, create an OAuth client for the Zapier app, then configure the client in Zapier to obtain access tokens. Rotate credentials periodically and grant only the necessary scopes (readonly for retrieval, write for updates).\nTip: store tokens securely and use token refresh flows to avoid downtime.
Core contact endpoints include GET /contacts/:contactId for retrieval, GET /contacts/ to list, and POST /contacts/ to create. For tasks, use POST /contacts/:contactId/tasks to create, and PUT /contacts/:contactId/tasks/:taskId to update. Notes and appointments have analogous endpoints under their respective paths.\nPractical use: fetch a contact, then pull its tasks and notes to populate a CRM dashboard or to trigger downstream automations.
Yes. Zapier App Connector can create, update, and delete tasks and notes tied to a contact. You can build workflows that reflect changes in GHL in your other apps, such as a project board or a support ticket system.\nConsider building test flows first to validate field mappings and data consistency.
You do not need to code, but a basic understanding of REST concepts helps. The Zapier app provides no-code triggers and actions, and you can map fields between GHL and your destination app. If you need advanced processing, you can add minimal code steps or webhooks, but it’s optional for typical integrations.
Test the connection by authenticating the GHL app in Zapier, then running a test pull for a contact and its related tasks or notes. Validate field mappings and ensure permissions (readonly vs write) align with the actions you intend to perform.\nUse logs and error messages to troubleshoot authentication or endpoint issues.
Due to high volume, we will be upgrading our server soon!
