Access to the Contacts API is secured with OAuth 2.0. Request the scopes you need (for example, contacts.readonly and contacts.write) and securely store tokens in Zapier.
Zapier authenticates to the GHL Contacts API using OAuth 2.0 tokens. The connected app in GHL provides client credentials that Zapier uses to obtain and refresh access tokens automatically.
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; contacts.write; 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: a new or updated contact in the source app; Action: create or update a contact in GHL using POST /contacts/ (and PUT /contacts/:contactId if updating).
Map fields such as name, email, phone, and tags; ensure the contactId is captured for updates; handle duplicates with idempotent operations.
POST /contacts/ (create) and PUT /contacts/:contactId (update).
name, email, phone
Trigger: new or updated task in Zapier; Action: create or update a task in GHL via POST /contacts/:contactId/tasks and PUT /contacts/:contactId/tasks/:taskId.
Map fields such as contactId, taskTitle, dueDate, and status; include notes if available.
POST /contacts/:contactId/tasks
contactId, taskTitle, dueDate
Trigger: new tag added in Zapier; Action: POST /contacts/:contactId/tags to apply the tag in GHL.
Map fields: contactId, tagName; ensure proper tag name formatting and idempotency.
POST /contacts/:contactId/tags
contactId, tagName
Automates repetitive data entry and keeps contacts, tasks, and notes in sync without writing code.
Enables rapid setup with drag-and-drop workflows, reducing time to value.
Scales with your business as data grows, with easy field mapping and error handling.
Key elements include API endpoints, authentication, data mapping, and automation workflows that connect GHL to the Zapier App Connector.
A specific URL path for an action in the GHL API, such as retrieving a contact or updating a task.
A real-time notification that triggers a workflow in an integrated app when a designated event occurs.
The process for proving identity and granting API access, typically via OAuth 2.0 tokens.
A token-based authorization method that grants controlled access to APIs for a limited time.
Automatically create or update contacts in GHL when records are created or updated in the connected app, keeping data consistent.
Create GHL tasks from Zapier triggers when a form is submitted or a deal progresses, ensuring workload visibility.
Aggregate user notes and activity into a single contact timeline for quick context.
Create a connected app in GHL and obtain client credentials, then configure OAuth 2.0 in Zapier.
In Zapier, select the GHL Contacts API app and authorize the connection, selecting the required scopes.
Test triggers and actions in a test workflow, verify data mapping, then deploy to production.
The Contacts API is a set of endpoints that let you create, read, update, and delete contact data in GHL. It enables programmatic access for automations and integrations with apps like Zapier. You can fetch contact details, their tasks, notes, and activities. To get started, create a connected app in GHL, request the necessary scopes (such as contacts.readonly and contacts.write), and configure OAuth 2.0 in Zapier to securely authenticate requests.
No deep coding is required. The Zapier App Connector provides a no-code interface to map fields and set triggers and actions. If you need more advanced logic, you can add code steps or use webhooks for custom flows.
Authentication uses OAuth 2.0 tokens. Zapier stores tokens securely and refreshes them automatically. Keep tokens secret and rotate if compromised; use scoped access to limit permissions.
Available endpoints include retrieving contacts, tasks, notes, and appointments, as well as creating and updating contacts and tasks. Some endpoints allow read-only access, while others enable creation and modification of data via POST, PUT, or DELETE operations.
Yes, you can delete contacts and tasks via DELETE endpoints (DELETE /contacts/:contactId and DELETE /contacts/:contactId/tasks/:taskId). Be mindful of cascading effects and ensure you have proper permissions before deletion.
There are rate limits to protect the API. If you hit a limit, Zapier will automatically retry after a cool-down. To optimize, batch requests and prefer incremental updates when possible.
Test the integration using Zapier’s built-in test tools and a sandbox GHL account. Verify each field mapping and endpoint behavior in a staging workflow before going live.
Due to high volume, we will be upgrading our server soon!
