The Contacts API uses OAuth 2.0 to securely grant access to your GHL data. Set the required scope (contacts.readonly) to start reading data from your connected accounts.
In Zapier App Connector, authorize the app to access your GHL account using the OAuth flow. Stored credentials allow safe, repeatable data pulls.
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; 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: When a contact is created or updated in GHL.
GET /contacts/:contactId
Key fields: contactId
Trigger: Periodic or on-demand sync of contacts.
Actions: Retrieve /contacts/ and optionally /contacts/:contactId/tasks and /contacts/:contactId/notes.
GET /contacts/
Key fields: contactId
Trigger: New contact creation in GHL.
Actions: POST /contacts/ to create, then POST /contacts/:contactId/tasks to add a follow-up task.
POST /contacts/; POST /contacts/:contactId/tasks
Key fields: contactId, taskId
Automate repetitive workflows without writing a line of code.

A standard authorization framework enabling secure delegated access to APIs like GHL.
A specific URL path in the GHL API used to read or manipulate resources.
An event in GHL that starts a Zapier workflow.
An operation performed in response to a trigger (e.g., POST, PUT, DELETE against an endpoint).
Set up a Zap to create a follow-up task in your project management app whenever you add a new contact in GHL.
Automatically save contact notes to your knowledge base system.
Update contact lifecycle stage based on completed tasks.
Log in to Zapier, choose the Contacts API app connector, and authorize access to your GHL account.
Choose contacts, tasks, notes, etc., to include in your zap.
Set up a trigger and action to automate your workflow.
You can read contact data, tasks, notes, and appointments using endpoints such as GET /contacts/:contactId and GET /contacts/:contactId/tasks. The scope shown (contacts.readonly) restricts you to read-only access; write operations require additional permissions. Test read-only flows in a sandbox environment to validate your setup. In production, request the write scope if you need to create or modify records.
GHL uses OAuth 2.0 for authorizing apps like the Zapier App Connector. When you first connect, you authorize the app to access your GHL data. Tokens are scoped to the permissions granted and should be refreshed before expiry; store credentials securely.
Common endpoints include GET /contacts/:contactId to fetch a contact, GET /contacts/ to list contacts, and GET /contacts/:contactId/tasks for tasks. Write endpoints such as POST /contacts/ and PUT /contacts/:contactId require the write scope; ensure your app configuration includes the needed permissions.
If you have write permissions, you can create or update contacts and tasks via POST, PUT, and DELETE endpoints. In read-only mode, data cannot be changed; upgrade your scope to enable modifications.
GHL enforces rate limits per app. Implement exponential backoff and retries to handle throttled requests. For large data sets, use pagination and batch processing where supported.
No-code automation is supported via the Zapier App Connector. Build complex workflows using triggers, actions, filters, and paths without writing code. For advanced scenarios, you can combine multiple steps and conditional logic.
Test your integration using Zapier’s built-in test feature and sample data. Validate each endpoint you plan to use, monitor task history, and adjust mappings as needed. Use a sandbox account when possible.
Due to high volume, we will be upgrading our server soon!
