To access the GHL Contacts API, use your API key or an access token issued by GHL. Store credentials securely and rotate tokens regularly.
Configure your Zapier App Connector credentials to securely authenticate requests to GHL and protect the data in transit and at rest.
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, 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: Retrieve a contact by ID to sync data or prefill a workflow.
Actions: Get contact, Update contact fields, manage tasks and notes linked to that contact.
Example paths: GET /contacts/:contactId and PUT /contacts/:contactId for updates.
Key fields: contactId, and related IDs for tasks, notes, or appointments.
Trigger: A new contact is created or a tag needs to be added automatically.
Actions: Create contact, add tags, assign to business, set initial notes.
Paths: POST /contacts/, POST /contacts/:contactId/tags
Key fields: contactId, businessId, tagId.
Trigger: When a contact task is created or completed.
Actions: Create task, update task, mark completed, list notes, add notes to a contact.
Paths: POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, GET /contacts/:contactId/tasks
Key fields: contactId, taskId, id for notes.
Automate data sync between GHL and Zapier without writing code.
Create and automate workflows across contacts, tasks, notes, and appointments.
Prototype complex processes quickly with builders and prebuilt triggers.
Understand the core terms used when connecting GHL via the Contacts API to Zapier App Connector.
A specific URL path and method that performs a function in the API, such as retrieving a contact or creating a note.
The method by which you prove identity to the API, often via API keys or tokens.
An event in your app that starts a Zap, such as a new contact or a task update.
An operation performed in response to a trigger, like creating a contact or updating a task.
Use a Zap to create a new contact in GHL when a form is submitted and assign initial tasks.
Automatically push task updates from GHL into Zapier to trigger follow-ups.
Mirror notes from GHL into your shared workspace via Zapier.
Collect your GHL API key and set up OAuth or token-based access for the Zapier app.
Enter credentials in the Zapier app settings and verify permissions (read vs write).
Create Zaps that call endpoints like GET /contacts/:contactId and POST /contacts/ to automate work.
The GHL Contacts API exposes endpoints to read and manage contact data, tasks, notes, and appointments. It connects to Zapier App Connector to automate workflows without writing code. Start with basic read endpoints to map fields into your Zaps, then expand to write endpoints for updates. If you’re new, begin with a simple pull of a contact record and gradually add actions like creating tasks or notes.
Some endpoints require write access, depending on the action. Read-only scopes let you fetch data, while write scopes enable creating, updating, and deleting. Ensure your API credentials grant the appropriate scope for the tasks you want to automate. Always test in a sandbox or development environment before going live.
Start with GET /contacts/:contactId to pull core data, then POST /contacts/ to create new records or PUT /contacts/:contactId to update. For workflow automation, pair these with triggers like new or updated contacts and follow with actions that update tasks, notes, or tags.
Use token-based authentication or API keys provided by GHL and configure them securely in Zapier App Connector. Avoid embedding credentials in workflows or logs. Rotate tokens periodically and use least-privilege scopes to minimize risk.
Yes. Triggers can be set for events such as a contact update or a new task, enabling real-time or near-real-time automation in Zapier. Pair triggers with actions to keep systems synchronized.
Rate limits vary by endpoint and plan. Plan for retries and exponential backoff in your Zaps. If you anticipate high traffic, batch requests where supported and stagger tasks to stay within quotas.
Endpoint availability is documented in your GHL API reference within the Zapier app. Use the endpoint list to guide which calls your Zaps will perform and test each path during setup.
Due to high volume, we will be upgrading our server soon!
