Scope: contacts.readonly. Use OAuth 2.0 for secure access and include the required permissions for reading contacts. Store tokens securely and rotate credentials regularly.
Zapier App Connector authentication uses API keys or OAuth depending on your setup; keep credentials confidential and manage token lifecycles within Zapier.

Key fields: contactId, email, name, phone, tags
Trigger: New or updated tasks in GHL propagate to task-management or project tools via Zapier.
Actions: Create/update tasks, sync statuses, assign owners, and keep task histories aligned.
Methods/Paths: GET /contacts/:contactId/tasks, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId
Key fields: taskId, contactId, title, dueDate, status
Trigger: Notes added or updated in GHL trigger actions in Zapier workflows.
Actions: Retrieve notes, create notes, fetch notes by id and attach to contacts.
Methods/Paths: GET /contacts/:contactId/notes, POST /contacts/:contactId/notes

A person or company in your GHL workspace with identifiable details such as name, email, phone, and associated tasks.
An action item linked to a contact, such as a follow-up call or meeting.
A quick memo or piece of information attached to a contact.
A specific URL path that performs an operation on GHL data, such as retrieving a contact or updating a task.
Trigger on contact updates in GHL and push key fields to your connected CRM or email tool to keep records in sync.
When a GHL task changes, create or update corresponding tasks in your PM tool to maintain alignment.
Archive notes from GHL into a document tool for audit trails and historical reference.
Create a Zapier connection and obtain your GHL API credentials with the proper scope (contacts.readonly).
Map endpoints like GET /contacts/:contactId and POST /contacts/ to your Zaps for data driving automations.
Create Zaps that trigger on contact changes and perform actions across connected apps.
The GHL Contacts API provides programmatic access to contact data, tasks, notes, and related entities. It enables developers and automation tools to read or modify records as permitted by your access scope. Using the Zapier App Connector, you can trigger automations and perform actions without writing code. This combination lets you automate workflows across CRM, marketing, and operations tools while maintaining data integrity.
No traditional coding is required for most common use cases. The Zapier UI lets you connect the GHL Contacts API endpoints, set up triggers, and define actions across apps. For advanced scenarios, you can still use custom webhooks or code steps, but the base workflow can be built with no code.
Common endpoints include GET /contacts/:contactId to retrieve a single contact and PUT /contacts/:contactId to update details. For workflow management, GET /contacts/:contactId/tasks and POST /contacts/:contactId/tasks enable synchronization of tasks. You can also retrieve notes with GET /contacts/:contactId/notes and create new notes with POST /contacts/:contactId/notes.
GHL authentication typically uses OAuth 2.0 with the appropriate scopes and stored tokens. The Zapier App Connector also requires its own secure authentication mechanism, which may involve API keys or OAuth, depending on how you set up the connection. Always protect credentials and use secure storage.
Yes. You can propagate changes in GHL to project management, CRM, email, and notes apps by triggering tasks and notes synchronizations. This ensures teams stay aligned as data updates occur in either system.
Map fields consistently across apps, handle optional fields gracefully, and log errors with retry strategies. Use id mappings for contacts and tasks, and validate data formats before sending requests to avoid failures.
For more resources, check the GHL API docs, Zapier help center, and community forums where integration patterns and use cases are discussed. You can also contact support for tailored guidance.
Due to high volume, we will be upgrading our server soon!
