GHL access uses OAuth 2.0. In the Zapier App Connector you will configure OAuth with the Contacts API client ID and secret and request scopes such as contacts.readonly to read data.
Set up the app in Zapier by creating an OAuth2 flow or API key method. Enter the client credentials from the Contacts API and define the authorization URL, token URL, and scopes.
The endpoints below cover reading and managing contacts, notes, tasks, and appointments. Use GET to read, POST to create, PUT to update, and DELETE where supported.
Trigger when a contact is created or updated in GHL to pull the latest data into Zapier and drive downstream actions.
Actions include fetching contact data via GET /contacts/:contactId and updating downstream systems accordingly.
GET /contacts/:contactId
contactId, name, email, phone, status
Trigger to fetch multiple contacts with pagination for batch processing.
Use GET /contacts/ to retrieve lists and then iterate items in Zapier to perform bulk updates.
GET /contacts/
businessId, page, pageSize, fields
Trigger on task creation or note addition for a contact to automate follow ups.
Create tasks with POST /contacts/:contactId/tasks and fetch notes with GET /contacts/:contactId/notes.
POST /contacts/:contactId/tasks
contactId, taskTitle, dueDate, priority
Automate common workflows without writing any code
Keep data synchronized across apps with built in error handling and retries
Scale processes as contact volumes grow without additional development time
This glossary explains core terms used in this guide and how they relate to GHL, the API, and the Zapier App Connector
A software interface that lets applications communicate. The Contacts API exposes endpoints to read and manipulate contact data.
A specific URL path in an API that performs a defined action such as retrieving a contact or creating a task.
A standard protocol for authorizing access to resources without sharing credentials. Used to connect the Zapier App Connector to the GHL API.
An event driven notification that lets apps alert each other when something changes, such as a new contact or note.
When a new contact is added in GHL, automatically create a task in your project tool or update a field via the API.
Push contact changes to Google Sheets or Airtable for real time reporting.
Use a batch style flow to update multiple contacts via a single workflow and keep systems in sync.
Add OAuth credentials and configure the Contacts API endpoints you will use
Complete the OAuth flow and test a simple read of a contact
Add actions that call GET, POST, or PUT endpoints like GET /contacts/:contactId to fetch data or POST /contacts/ to create new records
The Zapier App Connector supports OAuth 2.0 for secure access to the Contacts API. You will configure a client in the API provider and authorize Zapier to request the needed scopes. After setup you can test a simple read of a contact to confirm access. If your environment uses API keys, you can switch to a key based method and store the key securely in Zapier.
For retrieving contact data you will primarily use GET endpoints such as GET /contacts/:contactId and GET /contacts/. These endpoints allow you to fetch single or multiple contacts. You can also pull related data such as tasks and notes with GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes.
Common errors include authentication failures, missing required fields, and rate limits. Ensure tokens are refreshed before expiration, handle 429 responses with retries, and implement backoff logic. The API responses include status codes and error messages to guide retry timing.
Yes. You can create, update, and delete contacts using POST, PUT, and DELETE endpoints such as POST /contacts/ to create and PUT /contacts/:contactId to update. When designing your Zap, map fields from the trigger to the target fields in GHL to keep data consistent.
No heavy coding is required. The Zapier App Connector provides a no code automation interface. You will configure triggers and actions using the UI, while advanced use cases may require a bit of mapping and optional scripting in Zapier paths.
Available contact fields depend on your GHL setup. Common fields include contactId, name, email, phone, and status. You can also fetch related data such as tasks and notes using the corresponding endpoints.
API documentation is available in the developer portal for the Contacts API. It includes endpoint paths, required parameters, authentication methods, and example requests. You can use it to build and test your Zapier automations.
Due to high volume, we will be upgrading our server soon!
