Use the standard GHL authentication flows (OAuth 2.0 or API keys) and configure your Zapier app to securely store tokens to access Contacts data.
In Zapier, register your app credentials and set up OAuth2 or API key access so you can securely call the Contacts API from your automations.
GET /contacts/:contactId — Retrieve a single contact by ID GET /contacts/:contactId/tasks — List tasks for a contact GET /contacts/:contactId/tasks/:taskId — Get a specific task for a contact GET /contacts/:contactId/notes — List notes for a contact GET /contacts/:contactId/notes/:id — Get a specific note GET /contacts/:contactId/appointments — List appointments for a contact GET /contacts/ — List contacts GET /contacts/business/:businessId — List contacts for a business contacts.write — Create or modify contacts (through appropriate endpoints) 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 as completed DELETE /contacts/:contactId/tasks/:taskId — Delete a task POST /contacts/:contactId/tags — Tag a contact
Trigger: When you need to pull the latest details for a specific contact to start a workflow.
Actions: Fetch contact data, then map fields into your Zapier task or trigger, enabling downstream actions.
GET /contacts/:contactId
Key fields: contactId, includePrimaryDetails, includeRelatedData
Trigger: When a contact’s task data is needed for reporting or automation.
Actions: Retrieve tasks, filter by status, and push to a Zapier workflow for reminders or updates.
GET /contacts/:contactId/tasks
Key fields: contactId, status, dueDate
Trigger: Accessing a particular task to drive updates or completions.
Actions: Retrieve the task, then update status or create follow-up actions in other apps.
GET /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId
Fast setup: Build automations in minutes without writing code.
Cross-app automation: Sync contacts, tasks, notes, and appointments across platforms.
Unified data: Keep your GHL data consistent across apps and workflows.
This glossary covers core concepts like contacts, tasks, notes, endpoints, authentication, and data flow between GHL and the Zapier App Connector.
A person stored in GHL with associated tasks, notes, and activities.
A unit of work linked to a contact, with status and due date.
A specific API route used to access or modify data.
The process of proving identity to access the API, typically via OAuth2 or API keys.
Capture form data and push new contacts into GHL via the Contacts API, triggering welcome emails and onboarding tasks.
Create and assign tasks in GHL when new tickets arrive in your helpdesk, and notify teams via Zapier.
Auto-sync important notes to a contact timeline to keep all teams informed across apps.
Obtain GHL client credentials and configure them in the Zapier App Connector.
Select the needed endpoints and map GHL fields to Zapier fields for your workflows.
Run test calls, validate data integrity, and enable automations in production.
For the Contacts API with the Zapier App Connector, use OAuth 2.0 or API keys to authenticate. Store tokens securely in Zapier and refresh as needed. This ensures that your connect flows stay secure while accessing contact data. In many setups, OAuth 2.0 is recommended for long-lived integrations.
Read endpoints include retrieving a single contact, listing a contact’s tasks and notes, and listing all contacts. You can also fetch business-scoped contact lists. These endpoints are ideal for building read-only automation and reporting dashboards.
Yes. The Contacts API supports creating and updating contacts as well as adding tasks and notes. Use the POST and PUT endpoints to create or modify records, and use proper field mappings in Zapier to keep data consistent.
Test endpoints in Zapier using the built-in test step for triggers and actions. Validate response data against expected schemas, and handle errors with appropriate retries and alerts.
Be mindful of API rate limits and implement retries with backoff. If you hit limits, queue requests in Zapier or stagger calls to avoid failures in automations.
Yes. You can filter by businessId or other fields supported by the API, depending on endpoint capabilities. Use query parameters or path variables to narrow results before mapping to Zapier fields.
API documentation for endpoints appears in the GHL developer docs and the Zapier App Connector docs. Use these references to confirm parameter names, response structures, and authentication details.
Due to high volume, we will be upgrading our server soon!
