Use OAuth 2.0 to securely authorize your Zapier app with the Contacts API. Scope should include read and write permissions as needed. If API keys are supported, store them securely and rotate regularly.
Configure OAuth 2.0 in the Zapier App Connector to obtain access tokens for the Contacts API and securely sign all requests.
GET /contacts/:contactId — Retrieve a single contact with core fields; GET /contacts/:contactId/tasks — List tasks for a contact; GET /contacts/:contactId/tasks/:taskId — Retrieve a specific task; GET /contacts/:contactId/notes — List notes for a contact; GET /contacts/:contactId/notes/:id — Retrieve a specific note; GET /contacts/:contactId/appointments — List appointments for a contact; GET /contacts/ — List all contacts; GET /contacts/business/:businessId — List contacts by business; POST /contacts/ — Create a new contact; PUT /contacts/:contactId — Update a contact; DELETE /contacts/:contactId — Delete a contact; POST /contacts/:contactId/tasks — Create a task for a contact; PUT /contacts/:contactId/tasks/:taskId — Update a task; PUT /contacts/:contactId/tasks/:taskId/completed — Mark a task complete; DELETE /contacts/:contactId/tasks/:taskId — Delete a task; POST /contacts/:contactId/tags — Add tags to a contact.
Trigger: When a contact is created or updated in GHL, pull the latest contact data into Zapier.
Actions: Get contact by ID, list tasks for the contact, list notes for the contact, list appointments for the contact.
GET /contacts/:contactId
contactId, firstName, lastName, email, phone, customFields
Trigger: Task or note updates for a contact.
Actions: List/create/update tasks, list notes, update contact information.
GET /contacts/:contactId/tasks
contactId, taskId, noteId, status, dueDate
Trigger: Tag changes on a contact.
Actions: Add tags (POST /contacts/:contactId/tags), remove tags (DELETE /contacts/:contactId/tags/:tagId), list tags (GET /contacts/:contactId/tags).
POST /contacts/:contactId/tags
contactId, tagName, tagId
Build powerful automations without code to sync contact data, tasks, notes, and appointments across your stack.
Leverage prebuilt triggers and actions to accelerate workflows.
Secure, permission-scoped access with easy onboarding and monitoring.
A quick glossary of terms used when wiring GHL’s Contacts API to the Zapier App Connector, including endpoints, methods, triggers, actions, and authentication.
A specific URL path defined by the API that performs a discrete operation, such as GET /contacts/:contactId to retrieve a contact.
Process to verify identity and permissions before granting API access, typically OAuth 2.0 or API keys.
An event that starts a Zap or workflow, such as a contact being created or updated.
An operation performed by the integration in response to a trigger, such as creating a task or updating a contact.
Set up seamless bidirectional sync for contacts between GHL and your stack using the Contacts API via the Zapier App Connector.
Automatically tag contacts based on activity and attach notes to improve segmentation.
Create and assign tasks when contact events occur, keeping teams aligned.
Configure OAuth 2.0 in the Zapier App Connector to obtain access tokens for the GHL Contacts API.
Map the required endpoints (GET /contacts/:contactId, POST /contacts/, etc.) to Zapier triggers and actions.
Run tests against the sandbox, deploy to production, and set up error alerts and retries.
For authentication, use OAuth 2.0 with the Contacts API to securely authorize your Zapier app. This keeps credentials hidden and tokens refreshed automatically. If API keys are supported, store them securely and rotate them regularly.
CRM workflows benefit from endpoints like GET /contacts/:contactId, GET /contacts/:contactId/tasks, and POST /contacts/:contactId/tasks to fetch and update tasks. Listing notes and appointments helps build a complete contact profile.
Yes. Zapier can read and write contact data via endpoints such as GET, POST, PUT, and DELETE for /contacts and related resources. Ensure the correct scope (contacts.readonly for read-only access, or full scope for writes).
You can start with essential endpoints (read-only) and gradually add create/update endpoints as you validate fields and triggers. The step-by-step guide covers authentication and endpoint mapping first.
Use a test sandbox in your GHL or a dedicated test workspace in Zapier. Validate data mappings with sample records, and monitor logs to catch validation errors early.
API rate limits vary by plan. Use exponential backoff and retry logic in Zapier to handle spikes and avoid hitting limits.
Implement retries, error handling, and clear user-facing error messages. Use Zapier’s built-in tools to manage retries and to surface errors in task history.
Due to high volume, we will be upgrading our server soon!
