To access the Contacts API through GHL, you’ll typically use OAuth 2.0 or an API token with the proper scope. The Browserless connection leverages the token to authorize requests to contacts, tasks, notes, and more.
Generate an API token in Browserless and pass it in the Authorization header as Bearer {token}. Ensure the token has the scope contacts.readonly to match the page’s read-only access needs.
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
Triggered when you need a full snapshot of one contact along with its related tasks.
Actions: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes
Method paths include GET /contacts/:contactId and related sub-resources such as /tasks and /notes
Key fields: contactId, name, email, phone, taskId, status
Triggered to bring in a broader set of contacts for batch processing or syncing.
Actions: GET /contacts/, GET /contacts/business/:businessId
Method paths include GET /contacts/ and GET /contacts/business/:businessId
Key fields: contactId, businessId, name, email
Triggered when you add new contacts or update existing records.
Actions: POST /contacts/, PUT /contacts/:contactId, POST /contacts/:contactId/tasks
Method paths include POST /contacts/ and PUT /contacts/:contactId; POST /contacts/:contactId/tasks as needed
Key fields: contactId, name, email, phone
Automate data flow without writing code to keep contacts, tasks, and notes in sync across apps.
Build event-driven workflows that trigger actions in Zapier when contact data changes in GHL.

This glossary explains API terms, endpoints, and process flows related to the Browserless-GHL Contacts API integration.
Application Programming Interface: a documented set of rules that lets applications talk to each other and exchange data.
A specific URL path in an API that performs a defined function or returns data.
OAuth 2.0 is an authorization framework that enables secure delegated access to APIs.
A set of permissions granted to an app to access resources in an API.
Automatically create new contacts in your CRM when form submissions land in Browserless, using POST /contacts/.
Keep tasks and notes in sync between GHL and other apps with GET and POST endpoints.
Trigger automatic reminders or follow-ups when a contact’s data changes.
Create an API key and configure the proper scopes for contacts.readonly.
Enter the API key, set the base URL, and test a sample GET call against /contacts/:contactId.
Run end-to-end tests and monitor logs to ensure reliable data sync.
You can authenticate with OAuth 2.0 to access the GHL Contacts API. In some setups, an API token may also be used; ensure the token is stored securely and that the scope includes contacts.readonly. When using Browserless, you’ll pass the token in the Authorization header as Bearer {token}.
The available endpoints cover core contact data: retrieving a contact, its tasks, notes, and appointments; and creating or updating contacts, tasks, and tags. Use GET for reads, POST for creates, PUT for updates, and DELETE where supported. You can also fetch all contacts or by business to support broader sync needs.
No traditional code is required if you’re using the Browserless app connector. You can configure API keys, scopes, and endpoint calls within the Browserless UI and map data to your GHL Contacts API without writing custom scripts.
The required scopes should include at least contacts.readonly to view data. If you intend to modify data, you would request write permissions (e.g., contacts.write) as appropriate for your integration. Always follow the principle of least privilege.
Test the connection by issuing sample GET calls such as GET /contacts/:contactId and verify that data returns as expected. Check authorization headers, token scope, and response codes. Use Browserless logs to troubleshoot any issues.
Rate limits depend on your GHL plan and Browserless configuration. Plan your calls to avoid bursts, implement retries with exponential backoff, and monitor API usage in the Browserless and GHL dashboards.
Endpoint definitions are listed in the endpoint list section above. For concrete examples, refer to the individual endpoint paths such as /contacts/:contactId, /contacts/, and /contacts/:contactId/tasks to see typical request and response formats.
Due to high volume, we will be upgrading our server soon!
