Access is granted via OAuth 2.0 with a token scoped to contacts.readonly. In your GHL developer portal, create a client, authorize it, and exchange an access token for API requests.
In Zapier, configure OAuth 2.0 for the Zapier App Connector, provide the client credentials, set the redirect URI, and request the contacts.readonly scope to read data from GHL.
Key endpoints covered include: 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. For writable operations, such as POST, PUT, and DELETE on certain endpoints, those require appropriate scopes which are not enabled in the default read-only setup.
Trigger: a contact is created or updated in GHL to kick off a Zap.
Actions: read contact data, update CRM fields in Zapier, create tasks, or add notes in connected apps.
Path examples: GET /contacts/:contactId to pull base data, GET /contacts/:contactId/tasks for related tasks.
Key fields: id, email, firstName, lastName, phone, status, lastModified
Trigger: new or updated notes for a contact.
Actions: mirror notes into an external log, sync updates to the original GHL contact.
Methods: GET /contacts/:contactId/notes, GET /contacts/:contactId/notes/:id.
Key fields: id, noteId, createdAt, updatedAt, content, author
Trigger: new tasks created or existing tasks updated.
Actions: create/update tasks in the Zapier-connected app, mark as completed, sync due dates.
Paths: POST /contacts/:contactId/tasks to create, PUT /contacts/:contactId/tasks/:taskId to update, PUT /contacts/:contactId/tasks/:taskId/completed to complete, GET /contacts/:contactId/tasks to list.
Key fields: id, taskId, title, status, dueDate, completedAt
No-code setup lets teams automate complex workflows without writing code.
Instant data synchronization ensures your teams see up-to-date information across tools.
Flexible triggers and actions enable custom automations tailored to your business.
Key elements include API endpoints, authentication, access scopes, data models, and integration flows used to move data between GHL and the Zapier App Connector.
A specific URL path that you call to perform an action or retrieve data from the API.
Authorization framework used to grant secure access to APIs without sharing passwords.
A URL that receives push notifications when a specified event occurs.
The permissions granted by an access token, defining what data can be read or modified.
Automatically create tasks for sales reps when a new contact meets criteria.
Sync notes, tasks, and appointments to your CRM and helpdesk for a complete view.
Trigger post-appointment tasks and reminders in your project tool.
Create a GHL OAuth client and authorize it for the Contacts API with readonly scope, then test the connection.
Set up OAuth credentials in the Zapier App Connector, specify the redirect URI, and request the contacts.readonly scope.
Choose a trigger like New Contact, add actions to create tasks or notes, and test end-to-end.
The Contacts API in this integration primarily provides read access to contact data, including basic fields, tasks, notes, and appointments via GET endpoints. Writable operations require additional scopes and endpoints that are not included in the default read-only setup. If you need writes, you would typically request elevated scopes in GHL and configure the Zapier App Connector accordingly.
Yes. This integration is designed for no-code and low-code use, letting you build Zaps with triggers and actions without writing code. For advanced scenarios you can combine multiple steps, filters, and built-in logic in Zapier to create complex automations.
Authentication relies on OAuth 2.0. You will authorize the GHL Contacts API in the developer portal and then connect the app in Zapier using the same OAuth flow. Ensure the access token includes the contacts.readonly scope for read operations.
Read-only endpoints include GET /contacts and sub-resources like /contacts/:contactId/tasks, /contacts/:contactId/notes, and /contacts/:contactId/appointments. Writable endpoints such as POST, PUT, and DELETE require higher scopes and explicit permission from GHL. This guide focuses on read access by default.
Yes, API rate limits apply based on your GHL plan. If you approach the limit, implement retries with exponential backoff in your Zapier workflows. For high-volume use, consider batching or using webhooks to reduce polling.
Test the connection by authenticating, then using Zapier’s test feature to pull a sample contact and its related data. Review error messages and confirm the token has the correct scopes before proceeding.
Yes, you can filter data by contact identifiers, business identifiers, or search parameters supported by each endpoint. For example, GET /contacts/business/:businessId narrows results to a specific business, while GET /contacts/:contactId fetches a single contact.
Due to high volume, we will be upgrading our server soon!
