Use OAuth 2.0 with the scope ‘contacts.readonly’ to securely access read-only endpoints for contacts, tasks, notes, and appointments.
Store credentials securely in Zapier, leverage token refresh, and follow best practices for managing secrets when connecting to GHL.
Endpoints available: 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; 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 on a new or updated contact to pull related data such as tasks.
Actions: GET /contacts/:contactId and GET /contacts/:contactId/tasks to retrieve the contact and its tasks, then route the data to your CRM, spreadsheet, or project tool.
Methods: GET /contacts/:contactId and GET /contacts/:contactId/tasks
Key fields: contactId, taskId
Trigger when a task is updated to sync its status.
Actions: GET /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, and PUT /contacts/:contactId/tasks/:taskId to modify details.
Methods: GET /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, PUT /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId
Trigger on note creation or updates, and appointment changes for a contact.
Actions: GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments, and GET /contacts/:contactId/notes/:id
Key fields: contactId, id (noteId), appointmentId
Build powerful workflows without writing code, linking contacts, notes, and tasks across apps in minutes.
Automate data sync to keep teams aligned and reduce manual data entry.
Access rich, real-time customer context to personalize outreach and support.
Below are the core elements and processes you’ll work with when connecting the GHL Contacts API via the Zapier App Connector: endpoints, triggers, actions, data fields, and mapping rules.
A Contact represents a person in your CRM with a unique contactId and associated data such as tasks, notes, and appointments.
A Task is a to-do item linked to a specific contact, identified by taskId, used to track activities.
A Note is a text remark attached to a contact, stored under a notes collection with its own id.
An Endpoint is a URL path to perform a specific API operation (e.g., GET /contacts/:contactId).
Whenever a new form is submitted in your app, automatically create or update a contact in GHL via the Contacts API through Zapier.
Push new or updated tasks to your PM tool to keep teams aligned using endpoints like /contacts/:contactId/tasks and /contacts/:contactId/tasks/:taskId.
Post brief notes to a team chat when important notes are added to a contact.
Configure OAuth 2.0 with the contacts.readonly scope and securely store tokens in Zapier.
Select endpoints such as GET /contacts/:contactId and GET /contacts/:contactId/tasks to pull data.
Create Zaps that map fields (contactId, taskId, notesId) and trigger actions across apps.
The Contacts API exposes read-only endpoints such as GET /contacts/:contactId and GET /contacts/:contactId/tasks to pull data. Use the OAuth 2.0 flow with scope ‘contacts.readonly’ for secure access. Endpoints cover contacts, tasks, notes, and appointments, giving you a complete view of a contact’s activity. You can start with these read-only calls to explore data and plan your automations.
Authentication is handled via OAuth 2.0 between GHL and Zapier App Connector. Store tokens securely in Zapier and refresh them as needed. Always follow best practices for secrets management and least privilege when configuring scopes (e.g., only ‘contacts.readonly’ when possible).
No code is required to set up these integrations. Use Zapier App Connector to connect the Contacts API endpoints to your apps with simple triggers and actions. You can map fields like contactId, taskId, and notesId to create powerful automations quickly.
Yes. You can access notes and appointments through endpoints such as GET /contacts/:contactId/notes and GET /contacts/:contactId/appointments. These endpoints enable you to surface enriched context for outreach, support, or scheduling workflows without writing code.
Key data fields include contactId, taskId, notesId, appointmentId, and related relationships like tasks, notes, and notes/:id. Data mapping lets you synchronize details across apps and maintain consistency across systems.
API usage is governed by rate limits and quota depending on your GHL plan. Monitor calls in Zapier and implement efficient data polling strategies to stay within limits while keeping data up to date.
Explore the official docs for the Contacts API, end-to-end integration guides, and example zaps. You can also access tutorials and community resources to expand your no-code automation capabilities.
Due to high volume, we will be upgrading our server soon!
