Access to endpoints requires a valid OAuth 2.0 token or API key. Use the provided scope contacts.readonly for read operations, and safeguard credentials in Zapier with best‑practice storage and rotation.
Zapier authenticates requests to GHL endpoints via OAuth 2.0 or API keys. Configure your App Connector with secure credentials and test connections in a sandbox before going live.

Trigger: When opening a workflow for a specific contact, fetch the contact’s details with GET /contacts/:contactId.
Actions: GET /contacts/:contactId to pull core data, GET /contacts/:contactId/tasks to pull tasks, GET /contacts/:contactId/notes for notes, and GET /contacts/:contactId/appointments for related scheduling.
GET /contacts/:contactId
Key fields: contactId; optional taskId or noteId for deeper lookups.
Trigger: When a contact is updated, pull related tasks and notes to keep systems in sync.
Actions: GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and GET /contacts/:contactId/appointments as needed.
GET /contacts/:contactId/tasks
Key fields: contactId, taskId, noteId for precise mapping.
Trigger: Retrieve business context data via GET /contacts/business/:businessId to enrich CRM records.
Actions: GET /contacts/business/:businessId and related contact endpoints to associate business context with contacts.
GET /contacts/business/:businessId
Key fields: businessId, contactId.
No‑code automations between Contacts API and the Zapier App Connector save time, reduce errors, and empower non‑developers to build workflows quickly.
Experiment with drag‑and‑drop workflow builders, map fields visually, and test data flows without writing code.
Scale CRM operations by syncing contacts, tasks, notes, and business context across your tools with reliable, repeatable processes.
This glossary covers endpoints, triggers, actions, authentication, and data mapping used in linking the Contacts API with the Zapier App Connector.
An API is a set of rules that lets apps communicate and share data securely.
A specific function exposed by an API, accessible via a URL.
An event that starts an automation in Zapier when it occurs in the source app.
The process of verifying identity and access rights before granting an API request.
Automatically create or update contacts in GHL when a form is submitted, then pull related tasks and notes into Zapier for follow‑ups.
When a task is created in Contacts API, mirror it to your project management tool to keep teams aligned.
Attach business data to contacts and use it to drive segmentation, campaigns, and personalized outreach.
In GHL, generate an API key or OAuth 2.0 client to authorize Zapier requests securely.
Add the Contacts API as a connected app in Zapier, supply client secret, and set scope to contacts.readonly (and other scopes as needed).
Run test actions in Zapier, verify data mappings, and deploy your live workflows with monitoring.
The Contacts API exposes endpoints to read and manage contact data within GHL. You can use the Zapier App Connector to pull data, trigger workflows, and push updates between systems without writing code. Start with read operations to explore data and then extend to write operations as needed. Always validate your data mappings in a sandbox before going live. Regularly rotate credentials and restrict scopes to the minimum required for your automation to reduce risk.
Authentication typically uses OAuth 2.0 or API keys. In Zapier, configure your app credentials securely, request the necessary scopes (such as contacts.readonly), and store tokens securely. Test token refresh flows to ensure uninterrupted access.
No heavy coding is required. The Zapier App Connector provides a visual builder to configure triggers, actions, and data mappings. Some advanced scenarios may need simple scripting or field transformations, but most integrations can be completed via the UI.
The API includes endpoints for retrieving a single contact, their tasks, notes, appointments, and related business data, as well as endpoints for creating, updating, and deleting contacts and tasks. The exact endpoints you use depend on your automation goals.
Map fields by selecting source fields from the Contacts API (like contactId, name, email) and destination fields in Zapier. Use data transformation steps to normalize formats (dates, IDs) before passing them to downstream apps.
Yes. You can fetch a contact together with related resources like tasks, notes, and appointments. You can also pull business context to enrich records and workflows.
Due to high volume, we will be upgrading our server soon!
