To securely access the Contacts API from the Zapier App Connector, use OAuth 2.0 with scopes such as contacts.readonly and, when needed, contacts.write. Store tokens securely and refresh them as required.
In Zapier, configure your app’s OAuth credentials or API key. Use the standard redirect flow, request the necessary scopes, and protect your client secret.
GET /contacts/:contactId — Retrieve a single contact\nGET /contacts/:contactId/tasks — List tasks for a contact\nGET /contacts/:contactId/tasks/:taskId — Get a specific task for a contact\nGET /contacts/:contactId/notes — List notes for a contact\nGET /contacts/:contactId/notes/:id — Get a note\nGET /contacts/:contactId/appointments — List appointments\nGET /contacts/ — List all contacts\nGET /contacts/business/:businessId — List contacts for a business\nPOST /contacts/ — Create a new contact\nPUT /contacts/:contactId — Update a contact\nDELETE /contacts/:contactId — Delete a contact\nPOST /contacts/:contactId/tasks — Create a task for a contact\nPUT /contacts/:contactId/tasks/:taskId — Update a task\nPUT /contacts/:contactId/tasks/:taskId/completed — Mark task complete\nDELETE /contacts/:contactId/tasks/:taskId — Delete a task\nPOST /contacts/:contactId/tags — Add tags to a contact
Trigger when a contact is retrieved or updated in GHL so your downstream systems stay in sync.
Actions include creating tasks, notes, or tags for the contact (POST /contacts/:contactId/tasks, POST /contacts/:contactId/notes, POST /contacts/:contactId/tags).
Methods: GET /contacts/:contactId to fetch the contact, GET /contacts/:contactId/tasks to fetch tasks.
Key fields: contactId, taskId, noteId, businessId
Trigger when tasks are created or updated for a contact.
Actions: create, update, or delete tasks (POST/PUT/DELETE /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, DELETE /contacts/:contactId/tasks/:taskId); mark as completed.
Methods: GET /contacts/:contactId/tasks, GET /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId
Trigger when notes are added or updated for a contact.
Actions: create notes (POST /contacts/:contactId/notes), fetch notes (GET /contacts/:contactId/notes), get a single note (GET /contacts/:contactId/notes/:id).
Methods: GET /contacts/:contactId/notes, GET /contacts/:contactId/notes/:id
Key fields: contactId, noteId
Automate repetitive workflows without writing code
Centralize contact data across tools and teams
Rapid onboarding with pre-built actions and triggers
A concise glossary of core concepts to help you integrate the GHL Contacts API with the Zapier App Connector: endpoints, authentication, triggers, actions, and data fields.
Application Programming Interface: a set of rules that allows your app to talk to the GHL Contacts API.
An endpoint is a specific URL path you call to perform an action, such as retrieving a contact or updating a task.
OAuth 2.0 is the standard protocol for authorizing access to the GHL API securely.
A webhook or trigger notifies your app when data changes in GHL.
Automatically pull new contacts from GHL into your other apps via Zapier to keep data in sync.
When a task is updated in GHL, create a corresponding task in your project tool to reflect changes.
Attach contact notes to client records automatically to enrich CRM history.
Create your app in the GHL developer portal and obtain client credentials, then configure OAuth in Zapier.
Grant the necessary scopes like contacts.readonly and contacts.write, and test API calls.
Create Zapier zaps to sync contacts, tasks, notes between GHL and your tools.
The GHL Contacts API provides programmatic access to read, create, update, and delete contacts, tasks, notes, and appointments, enabling seamless automation and data flow between GHL and your other apps. Use it to surface data in Zapier or push updates from your tools into GHL.\nWith proper authentication and scopes, you can tailor what data is accessible and control how your workflows act on that data.
No heavy coding is required to use the Zapier App Connector. You’ll configure triggers, actions, and field mappings through the UI, then test and enable your zaps. For advanced needs, you can extend with custom fields or multi-step workflows, but it is designed for no-code use.
OAuth 2.0 is used to authorize access to the GHL API. Your app will exchange client credentials for access tokens, request scopes like contacts.readonly or contacts.write, and refresh tokens as needed. This keeps credentials secure and access limited to what you request.
The available endpoints include reading contacts, their tasks, notes, and appointments, as well as creating or updating contacts and related data. See the endpoint list in the content for a complete, mapped set of paths and supported operations.
Use Zapier’s built-in test feature to run API calls against the GHL Contacts API. Inspect responses, adjust field mappings, and iterate until you achieve the desired data flow between GHL and your connected apps.
Yes. You can update contacts and tasks using PUT, POST, and DELETE endpoints. Ensure your OAuth scopes include the required permissions and validate changes with test calls before deploying in production.
API credentials can be managed in the GHL developer portal under your app credentials. You’ll find the CLIENT_ID, CLIENT_SECRET, and redirect URI needed for OAuth authentication. Keep these secrets secure and rotate them as recommended.
Due to high volume, we will be upgrading our server soon!
