To access the Contacts API, you’ll authenticate using OAuth 2.0 with your GHL account and grant the Zapier App Connector the requested scope (contacts.readonly).
In Zapier, create a new connection by linking your GHL credentials and selecting the Contacts API scope. Follow the prompts to authorize access.
1) GET /contacts/:contactId — Retrieve a single contact\n2) GET /contacts/:contactId/tasks — List tasks for a contact\n3) GET /contacts/:contactId/tasks/:taskId — Get a specific task for a contact\n4) GET /contacts/:contactId/notes — List notes for a contact\n5) GET /contacts/:contactId/notes/:id — Get a specific note\n6) GET /contacts/:contactId/appointments — List appointments for a contact\n7) GET /contacts/ — List all contacts\n8) GET /contacts/business/:businessId — Get business-related contacts\n9) contacts.write (scope)\n10) POST /contacts/ — Create a contact\n11) PUT /contacts/:contactId — Update a contact\n12) DELETE /contacts/:contactId — Delete a contact\n13) POST /contacts/:contactId/tasks — Create a task for a contact\n14) PUT /contacts/:contactId/tasks/:taskId — Update a task\n15) PUT /contacts/:contactId/tasks/:taskId/completed — Mark a task as completed\n16) DELETE /contacts/:contactId/tasks/:taskId — Delete a task\n17) POST /contacts/:contactId/tags — Tag a contact

Trigger: Retrieve all tasks for a given contact as part of a workflow.
Actions: List tasks for a contact, view individual task details.
GET /contacts/:contactId/tasks
Key fields: contactId, optional query parameters (status, since).

GET /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId.
Rapid automation setup without writing code—design workflows visually in Zapier.
Drag-and-drop workflow design with real-time data from GHL Contacts API endpoints.
Unified data access across contacts, tasks, notes, and appointments for streamlined processes.
Understand core concepts and how they apply to connecting GHL with the Zapier App Connector to automate contact workflows.
OAuth 2.0 is an authorization framework that lets the Zapier App Connector access GHL resources without sharing user credentials.
A specific URL path that performs an action on the GHL Contacts API.
A permission set like contacts.readonly that defines what the app can access.
The linked account between GHL and the Zapier App Connector used to perform actions.
Create a Zap that pulls new contacts and auto-creates related tasks in your project management tool, ensuring teams stay aligned from day one.
Bridge notes from GHL into your CRM or document storage to keep context rich and accessible across apps.
Trigger reminders or follow-up tasks when appointments are scheduled or updated to boost engagement.
In Zapier, add a new connection, choose the Contacts API, and authorize access using OAuth 2.0 with your GHL account.
Map fields and set up triggers for required endpoints (contacts, tasks, notes, etc.), then test the calls.
Run tests in Zapier, verify data flows, and monitor logs to ensure reliability and accuracy.
Read access is provided through a set of GET endpoints that allow you to retrieve contacts, their tasks, notes, and appointments. Example calls include fetching a single contact by ID or listing all tasks for a contact. You can combine multiple endpoints in a single Zap to assemble richer data sets. If you need more data, you can paginate through lists using query parameters.\nTip: Start with GET /contacts/:contactId to validate your connection, then expand to related resources like tasks and notes as needed.
Authentication is handled via OAuth 2.0. In Zapier, you’ll authorize the GHL account to grant the Zapier App Connector access to the Contacts API with the defined scopes. After initial authorization, the connector will use access tokens to perform API calls on your behalf. If tokens expire, the refresh mechanism will renew them automatically.\nAlways ensure you’re authorizing the correct GHL account and that the connected app has the required read permissions.
The primary scope for read operations is contacts.readonly. This scope allows viewing contact data, tasks, notes, and related resources but does not permit creating, updating, or deleting records. If write access is needed, an elevated scope (e.g., contacts.write) must be requested and approved.\nAlways apply the principle of least privilege when configuring your Zapier connections.
Yes—write operations are supported when using the appropriate scopes. Endpoints for creating, updating, and deleting contacts, tasks, and tags exist (e.g., POST /contacts, PUT /contacts/:contactId, DELETE /contacts/:contactId). Use these cautiously and consider adding approval steps in your workflow.\nTest changes in a sandbox or staging environment before deploying to production.
Zapier connections respect API rate limits set by GHL. If limits are reached, requests may be delayed or fail with a rate limit error. To mitigate this, batch calls, stagger polls, or add retries with exponential backoff in your Zapier workflows.\nConsider caching frequently requested data in intermediate steps to reduce repeated calls.
Basic no-code familiarity is sufficient to build Zaps that read data from the Contacts API. For advanced use cases, you may want to leverage filters, paths, and multi-step workflows in Zapier. No formal coding is required, but some JSON understanding helps when mapping fields.\nExperiment with test data to understand how responses look and how to handle errors gracefully.
Endpoint responses and connector logs can be viewed directly in Zapier during testing and in your connected app’s activity logs. Use these to troubleshoot authentication, parameter mappings, and data formatting.\nSet up alerting or dashboards outside Zapier if you need centralized monitoring.
Due to high volume, we will be upgrading our server soon!
