Authenticate calls to the Contacts API with your GHL API key or OAuth credentials to establish a secure connection and control access to data.
The Zapier App Connector authenticates with GHL using OAuth 2.0 and required scopes. Store credentials securely in Zapier and rotate keys as needed.
GET /contacts/:contactId – Retrieve a single contact by ID; GET /contacts/:contactId/tasks – List a contact’s tasks; 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 note; GET /contacts/:contactId/appointments – List appointments for a contact; GET /contacts/ – List all contacts; GET /contacts/business/:businessId – List contacts for a business; POST /contacts/ – Create a 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 new contact is added or updated in the Contacts API.
Actions: Create or update contact in GHL; optionally create related tasks and notes.
POST /contacts/
email, name, phone
Trigger: Retrieve a contact and its tasks and notes from the Contacts API.
Actions: Get contact data and its related tasks and notes; output to Zapier.
GET /contacts/:contactId
contactId
Trigger: Tag updates on a contact.
Actions: Add or remove tags using POST /contacts/:contactId/tags.
POST /contacts/:contactId/tags
contactId, tags
No-code setup lets you connect GHL with ZOKO without writing code.
Automate repetitive workflows like syncing contact data and tasks with a few clicks.
Faster go-live and easier maintenance compared to custom integrations.
The key elements are endpoints, authentication, data mapping, triggers, and actions. Data flows between GHL and ZOKO through Zapier to automate workflows.
Application Programming Interface: a set of rules that lets software programs communicate with a service.
Webhook: a real-time push notification that sends data to your app when an event occurs.
OAuth 2.0: an authorization framework that enables apps to access a user’s data without sharing credentials.
Endpoint: a specific URL in an API that performs a defined action.
Use duplicate checks and field mappings to identify and merge or remove duplicates, while keeping notes in sync.
When a new contact is created, automatically generate a follow-up task for your team and assign it based on contact data.
Populate onboarding notes when a contact progresses through stages and reflect updates in real time.
Gather your GHL API key and OAuth client details, and create or select the Zapier App Connector credentials.
Install the Contacts API integration in Zapier, authorize access, and select scopes for contacts, tasks, and notes.
Create a test Zap, run it, and verify data flows correctly before going live.
The GHL Contacts API provides programmatic access to contacts, tasks, notes, and appointments. It supports standard REST operations to read, create, update, and delete records. Authentication is required, usually via API keys or OAuth tokens. The API enables you to build custom automations and integrations with other apps.
The Zapier App Connector (APPNAME) is a no-code integration layer that connects apps like GHL to Zapier workflows. It uses OAuth 2.0 for secure authorization and exposes triggers and actions that you can map in Zaps. This makes it easy to automate cross-platform processes without writing code.
Common endpoints include listing contacts (GET /contacts/), retrieving a contact (GET /contacts/:contactId), and accessing related data such as tasks (GET /contacts/:contactId/tasks) and notes (GET /contacts/:contactId/notes). For write operations, you’ll typically use POST, PUT, or DELETE on /contacts or related sub-resources. Start with reads to understand data shape before updates.
Yes. You can update existing contacts with PUT /contacts/:contactId. Ensure you supply the contactId and the fields you want to update. Partial updates are supported in many APIs, so you can send only the changed fields to minimize payloads.
Field mappings are defined in the Zapier setup screen. Map source fields from GHL to target fields in APPNAME (and vice versa) so that contacts, tasks, and notes flow correctly. Use sample data during testing to validate mappings before going live.
Rate limits depend on your GHL plan and the API tier. If you hit limits, you may need to implement backoff strategies in Zaps or stagger requests. Consider batching actions where supported and caching lookups when possible.
API documentation is available on the GHL developer portal and in the Zapier App Connector docs. The GHL docs provide endpoint details, authentication methods, and example requests. The Zapier docs explain how to configure triggers, actions, and field mappings.
Due to high volume, we will be upgrading our server soon!
