To access the GHL Contacts API from Ontraport, obtain an OAuth 2.0 access token and grant the necessary scopes (including contacts.readonly and, where appropriate, write permissions). Exchange authorization codes for access and refresh tokens and securely store them for ongoing calls.
Ontraport authentication is configured within the app connection settings. Ensure Ontraport API access is enabled and you have valid credentials to authorize requests from GHL.
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: when a contact is created or updated in Ontraport, fetch the contact via GET /contacts/:contactId and push updates to GHL to keep both systems aligned.
Actions: upsert the contact in GHL, and attach related tasks and notes as needed to reflect Ontraport data.
GET /contacts/:contactId
Key fields: id, email, firstName, lastName
Trigger: new or updated tasks or notes in Ontraport trigger actions in GHL when linked to the same contact.
Actions: map to GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes to keep activity in sync; create or update in GHL as needed.
GET /contacts/:contactId/tasks
Key fields: taskId, subject, dueDate, completed
Trigger: Ontraport appointments update triggers calendar events in GHL.
Actions: push appointment data to GET /contacts/:contactId/appointments in GHL to create or update calendar events.
GET /contacts/:contactId/appointments
Key fields: appointmentId, startTime, endTime, location
Automate data sync without writing code using pre-built actions and mapping templates.
Maintain a single source of truth for contact data across Ontraport and GHL.
Speed up deployments with low-code configurations and real-time sync.
Elements: endpoints, triggers, actions, and data fields. Processes: mapping, authentication setup, error handling, and testing to ensure reliable sync.
A set of endpoints that allow apps to communicate programmatically.
A specific URL path in an API that performs a defined operation.
An authorization framework to obtain access tokens securely for API calls.
A callback mechanism that delivers real-time data to another app.
Pull external data such as company size or social profiles into Ontraport and reflect it in GHL.
When a contact changes, automatically create a task in Ontraport and update the GHL record.
Sync Ontraport appointments to a central calendar in GHL for easier planning.
Decide which contact fields, tasks, notes, and appointments to sync between Ontraport and GHL, and create field mappings.
Set up OAuth 2.0 or API keys for each system, then run test calls like GET /contacts/:contactId to verify data flow.
Activate the integration and monitor sync status with logs and alerts.
The GHL Contacts API requires an access token with the appropriate scope. Ensure the scope is set to read-only by default, and request write permissions only when needed. During setup, authorize the connection and test endpoints to confirm correct data flow. Use GET /contacts/:contactId as a validation example.
Essential endpoints include GET /contacts/:contactId to fetch a contact, GET /contacts/:contactId/tasks to pull tasks, and GET /contacts/:contactId/appointments to pull calendar events. Also consider notes endpoints (GET /contacts/:contactId/notes) and write endpoints (POST /contacts/, PUT /contacts/:contactId) to keep systems in sync.
No coding is required thanks to prebuilt templates and drag-and-drop configurations in the Zapier App Connector. Advanced logic can be added via optional steps if your use case requires it, but it isn’t necessary for standard syncing.
GHL uses OAuth 2.0 to authorize API access and Ontraport can be connected via API keys or OAuth depending on your setup. You’ll configure token exchange and refresh flows, then test scopes to ensure access to the needed endpoints.
Yes. You can map custom fields between Ontraport and GHL using the mapping interface in your connection settings. If a field doesn’t exist in one system, create a corresponding custom field to maintain data alignment.
Deleted contacts can be handled as tombstones in GHL or removed from GHL based on your configuration. Use deletion handling in the integration to skip or remove records and trigger cleanup workflows as needed.
View sync status and logs in your integration dashboard, including timestamps, endpoint responses, and error details. Enable alerts to get notified of failures, retries, and latency.
Due to high volume, we will be upgrading our server soon!
