Authenticate your Zapier connection to the Contacts API using your GHL API credentials and the required scope (contacts.readonly). Store credentials securely and rotate keys regularly.
In Zapier, create an app connection using OAuth2 or an API key, then authorize the Contacts API integration so Zapier can read contact data and manage items as permitted by scope.
Core endpoints covered by Paths by Zapier: GET /contacts/:contactId; GET /contacts/:contactId/tasks; GET /contacts/:contactId/tasks/:taskId; GET /contacts/:contactId/notes; GET /contacts/:contactId/notes/:id; GET /contacts/:contactId/appointments; GET /contacts/; GET /contacts/business/:businessId; POST /contacts/; PUT /contacts/:contactId; DELETE /contacts/:contactId; POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId/tasks/:taskId; POST /contacts/:contactId/tags
Trigger: when a contact is viewed or updated in GHL, Zapier can react and pull the latest data.
Actions: search, retrieve, or sync contact data into other apps via Zapier.
GET /contacts/:contactId
contactId, email, firstName, lastName
Trigger: when a task is created or updated for a contact.
Actions: list tasks, filter by status, or create/update tasks from Zapier.
GET /contacts/:contactId/tasks
taskId, status, title, dueDate
Trigger: new or updated notes for a contact.
Actions: fetch notes, create or update notes from Zapier.
GET /contacts/:contactId/notes
noteId, content, createdAt
Automate repetitive tasks without writing code.
Keep data synchronized between GHL and your apps in real-time.
Build multi-step workflows using triggers and actions.
This glossary covers API endpoints, authentication, triggers, and data fields used when connecting the Contacts API to Zapier.
A specific URL path and HTTP method used to interact with an API.
The process of proving identity and obtaining access to API resources.
A URL that receives real-time events from a source system.
An event that starts a Zap workflow.
Create a Zap that creates a new contact in the Contacts API whenever a form is submitted in another app, saving time and reducing manual entry.
When a new task is created in the Contacts API, automatically mirror it in your project management tool and keep both in sync.
Automatically pull updates from tickets into contact notes to keep context ready for agents.
Obtain and enter your GHL API credentials to authorize the connection from Zapier.
Select endpoints such as GET /contacts/:contactId and map fields to Zapier actions to shape your workflows.
Set up triggers and actions to automate contact workflows across apps with minimal setup.
Yes. The core endpoints include retrieving a contact by ID (GET /contacts/:contactId) and reading related data such as tasks, notes, and appointments. You can also access the full contact list and business-specific data via endpoints like GET /contacts/ and GET /contacts/business/:businessId. Use these to populate fields in your Zaps and drive automation without manual data entry. Authentication, error handling, and pagination are covered in the setup steps to ensure reliable data flow.
To authenticate, configure OAuth2 or API key for your Zapier app and attach it to the Contacts API connection. Store credentials securely, grant only the necessary scope (contacts.readonly) for read operations, and rotate keys regularly. After setup, test the connection inside Zapier’s test flow. Use Zapier’s authentication helpers to refresh tokens if needed and monitor for authorization errors.
Yes. You can read and write depending on scopes. With appropriate permissions (such as contacts.write), you can update contacts and associated tasks and notes from Zapier by mapping to PUT/POST/DELETE endpoints. Always validate IDs and handle error responses gracefully. Consider using idempotent actions and upsert patterns to prevent duplicate records.
Webhooks allow real-time updates from GHL to Zapier by sending events to a Zapier webhook URL. Zapier can receive these events as triggers and start workflows immediately. If webhooks are not available or suitable, you can implement polling triggers by periodically calling endpoints to check for changes.
Common fields include contactId, email, firstName, lastName, phone, and notes. When you pull tasks, useful fields are taskId, status, title, dueDate, and completed. Notes include noteId, content, and createdAt. Map these to Zapier fields to drive actions like creating or updating records.
API rate limits can apply; if you exceed them, implement exponential backoff and retries in Zapier. Plan accordingly to avoid failures. Batch updates where possible and cache data on the Zapier side to minimize repeated calls.
You can find the full endpoint reference in the Endpoint List section of this guide. It enumerates core endpoints such as GET /contacts/:contactId, GET /contacts/:contactId/tasks, and others used by Paths by Zapier. If you need more endpoints, consult the API documentation or request access to additional resources.
Due to high volume, we will be upgrading our server soon!
