Authenticate requests securely using the GHL Contacts API scope (contacts.readonly). Use your API key or OAuth token as required by your setup.
Configure OAuth2 or API token credentials in the Zapier app, granting the contacts.readonly scope to access contact data.
Sample endpoints 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 when a new or updated contact is available from GHL to keep your app in sync.
Actions include fetching a contact’s full profile, retrieving related tasks, and pulling notes.
GET /contacts/:contactId
Key fields: contactId, firstName, lastName, email, phone, tags, notes, tasks
Trigger when a new or updated task for a contact is created or changed.
Actions: list tasks, create or update tasks, mark complete.
GET /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId
Key fields: taskId, title, completed, dueDate, priority
Trigger when notes for a contact are added or updated.
Actions: list notes, create notes, retrieve specific notes.
GET /contacts/:contactId/notes; GET /contacts/:contactId/notes/:id
Key fields: noteId, content, author, createdAt
Automate contact data flow between GHL and your app without writing code.
Create cross-system workflows that react to new contacts, tasks, or notes.
Save time with repeated, error-free data synchronization and reporting.
Key elements and processes covered here include API endpoints, authentication, data fields, and how webhooks drive real-time updates.
An Application Programming Interface that lets software applications communicate with each other.
A specific URL in an API where you can request or modify data.
The method used to verify identity and grant access to API resources.
A URL endpoint that the API calls to push real-time data to your app.
Use data from the Contacts API to segment audiences in your app and trigger targeted workflows.
Send real-time notifications when new contacts are created or updated.
Synchronize tasks between GHL and your project tools to keep teams aligned.
Obtain OAuth tokens or API keys and grant the contacts.readonly scope.
Set up triggers and actions to call GET and POST endpoints for contacts, tasks, and notes.
Test in a staging environment, review logs, and deploy to production.
The GHL Contacts API exposes endpoints to read and manage contact data and related resources. This page focuses on reading and syncing data from GHL to your app via the Zapier App Connector. With the Contacts API, you can retrieve a contact’s core details, tasks, notes, and appointments to fuel automated workflows without writing server code.
Authentication supports API tokens and OAuth2 tokens. In Zapier App Connector, configure credentials and request the needed scopes (e.g., contacts.readonly) to access contact data. Secure storage of credentials and rotating tokens are recommended; always follow your org’s security standards when integrating with GHL.
Endpoints include read operations like GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and GET /contacts/:contactId/appointments, among others. Write endpoints such as POST /contacts/, PUT /contacts/:contactId, and DELETE /contacts/:contactId exist with appropriate scopes; refer to your API docs for full details.
Yes, you can write data back to GHL when you have the correct scopes (e.g., contacts.write). The example endpoints show how to create and update contacts and tasks. In practice, follow best practices for safe updates and use idempotent calls to avoid duplicates.
No code is required to set up the integration. Zapier App Connector provides trigger and action blocks that map to GHL endpoints. However, a basic understanding of your data model helps create powerful automated workflows and reduces troubleshooting.
Use Zapier’s built-in test feature to simulate API calls against the GHL endpoints and verify responses. You can also use GHL’s sandbox or a staging environment to validate permissions and data fields before going live.
Rate limits depend on your GHL plan and endpoint usage. Plan accordingly and implement backoff strategies in your Zapier workflows. Monitor quota usage via the API dashboard and apply batching where possible to avoid hitting limits.
Due to high volume, we will be upgrading our server soon!
