Access to the Contacts API requires OAuth 2.0 tokens and a defined scope. In this setup the scope is contacts.readonly for read access to core data.
Authorize requests from GHL to NGP VAN using your NGP VAN credentials or API key. Store credentials securely and rotate them regularly.
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: a new or updated contact in NGP VAN prompts a fetch in the Contacts API to mirror changes.
Actions: pull contact details notes and tasks map fields and create or update the contact in GHL via the Contacts API.
/contacts/:contactId
contactId firstName lastName email phone notes tasks
Trigger: task updates in the Contacts API propagate to NGP VAN.
Actions: fetch and push task data including id status and due date between systems.
/contacts/:contactId/tasks
taskId contactId title dueDate status completed
Trigger: marking a task as completed updates both systems.
Actions: call the endpoint to complete a task via PUT /contacts/:contactId/tasks/:taskId/completed.
/contacts/:contactId/tasks/:taskId/completed
taskId contactId completed
Fast no code automation using the Zapier App Connector enabling seamless data flow without custom development.
Consistent data across systems including contacts tasks notes and appointments.
Secure scalable workflows with token based authentication and role based access.
A quick glossary of terms and the processes used to connect GHL Contacts API to NGP VAN via a no code connector.
API stands for Application Programming Interface a set of rules that lets software communicate and exchange data.
An endpoint is a specific URL in an API that performs a defined action such as retrieving a contact or updating a task.
Scopes define what data an app can access and what actions it can perform on behalf of a user.
Authentication verifies identity to grant access typically via OAuth tokens or API keys.
Set up a trigger for new or updated contacts to push to Contacts API instantly.
Aggregate tasks from both systems into a single team dashboard.
Synchronize notes and activity history for a complete record.
Obtain API keys from GHL and enable the contacts.readonly scope for read access to contacts tasks and notes.
Define how fields map between NGP VAN and Contacts API and set the endpoints to call.
Run tests validate data integrity monitor logs and go live with the integration.
The Contacts API lets you read core contact data including identifiers names emails and phone numbers along with associated notes tasks and appointments. Use the endpoints to fetch a single contact or multiple records for syncing and reporting. Ensure your app scope matches the data you need.
Authentication is done via OAuth 2.0 tokens or API keys. For GHL use the OAuth flow to obtain a token and include it in requests. For NGP VAN use your secure integration credentials. Rotate credentials regularly and store them securely.
Yes you can retrieve notes and tasks for a given contact using the endpoints shown. You can also fetch lists of tasks and notes to display in dashboards and reports.
Write operations exist for creating updating and deleting records such as contacts and tasks. Use POST PUT and DELETE endpoints as appropriate with correct payloads.
Map fields carefully for consistency across systems. Use unique identifiers like contactId and taskId to align records and apply transformation rules if needed.
Common errors include invalid tokens expired scopes and mismatched field mappings. Check credentials refresh tokens verify scopes and validate endpoint paths and payload structures.
Endpoint details and examples are available in the API docs for the Contacts API and the NGP VAN integration. Use sample requests to test calls and verify responses.
Due to high volume, we will be upgrading our server soon!
