Access to Contacts data requires proper authentication. Use your GHL client credentials to obtain a bearer token and include it in the Authorization header when calling endpoints like GET /contacts/:contactId or POST /contacts/.
Zapier securely stores connection credentials. Create a new connection to the GHL Contacts API within Zapier, authorize it, and map tokens for each workflow.
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 API permission: 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: When a specific contact is requested or updated, fetch the latest profile data into Zapier to start a workflow.
Actions: Retrieve detailed contact data, then pull related tasks and notes for a complete view.
GET /contacts/:contactId
contactId, name, email, phone, tags, custom fields
Trigger: Retrieve a contact’s task list when a workflow runs.
Actions: List tasks, filter by status, and pass task data to downstream steps.
GET /contacts/:contactId/tasks
contactId, taskId, title, dueDate, status
Trigger: Fetch notes when a contact is opened or updated.
Actions: Retrieve notes and attach them to a contact record in Zapier.
GET /contacts/:contactId/notes
contactId, noteId, content, createdAt
Instant data access without writing code – map fields and trigger workflows with clicks.
Automate routine tasks like syncing contacts, notes, and tasks between GHL and your apps.
Scale automation across departments with reusable templates and secure credentials.
A quick glossary of the terms and processes used throughout this integration guide.
A specific URL path that performs a defined action on a resource, used to request data or make changes.
A secure token used to authorize requests to the GHL API or Zapier app connector.
A data object exposed by the API, such as a contact, task, or note.
An open standard for token-based authorization used by many APIs, including GHL and Zapier connections.
Set a Zapier trigger to create a new contact in GHL when a new lead arrives, and enrich it with notes and tasks.
Keep contact data synchronized in both GHL and connected apps, updating fields in real-time.
Aggregate notes and tasks from GHL into enriching data for marketing, sales, or support workflows.
In Zapier, add a new connection and authorize access to the Contacts API in GHL.
Pick a trigger like New or Updated Contact and map fields to an action such as Create or Update a contact.
Test the workflow end-to-end, then deploy and monitor performance and data consistency.
Yes. You will need a valid GHL account and API access to authenticate requests. Use OAuth 2.0 or API keys as configured in your GHL developer settings, then connect those credentials in Zapier. Once connected, you can pull or push contact data between GHL and your apps. In practice, test your trigger and action steps to ensure data maps correctly and errors are surfaced clearly.
Endpoints like GET /contacts/:contactId and GET /contacts/:contactId/tasks provide core data for most workflows. For larger operations, use POST /contacts/ to create contacts and PUT /contacts/:contactId to update them. Understanding response fields and pagination helps you design reliable automations.
Authenticate once via your GHL credentials in Zapier, then renew tokens as needed. Use secure storage and avoid embedding tokens in scripts. If you see 401 errors, verify scope (contacts.readonly) and ensure the token has the right permissions.
Yes. You can fetch multiple relationships by using dedicated endpoints like GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes. For bulk operations, loop over results in Zapier or use a batch endpoint if your GHL instance supports it.
Zapier connections can be tested in development with a sandbox or by using test data. Some accounts offer a sand-boxed environment; otherwise, test with a small dataset and monitor logs for errors.
Yes. The API supports creating and updating contacts via POST /contacts/ and PUT /contacts/:contactId. Map fields from your Zapier trigger to the corresponding GHL fields. Validate required fields to prevent failures.
If errors occur, inspect the HTTP status code, error message, and endpoint path. Check authentication tokens, scopes, and rate limits. Re-authenticate if tokens expire and review logs in both GHL and Zapier.
Due to high volume, we will be upgrading our server soon!
