Requests to the Contacts API require a valid access token tied to your GHL account. Use your app credentials from LeadCars to obtain an OAuth 2.0 token and include it as a Bearer token in API calls.
LeadCars authenticates via OAuth 2.0 with the necessary scopes for contacts.readonly and beyond. Store tokens securely and refresh as needed.
Key endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/, PUT /contacts/:contactId, and DELETE /contacts/:contactId to manage contacts and related data.
Trigger: when you need a detailed view of a contact, including tasks and notes.
Actions: GET /contacts/:contactId; pull complete profile, recent activity, and associated tasks for a 360-degree view.
GET /contacts/:contactId
Key fields: contactId, name, email, phone, company
Trigger: to build a directory for outreach and segmentation.
Actions: GET /contacts/ with pagination and filtering by businessId or tag.
GET /contacts/
Key fields: contactId, name, email, status
Trigger: when a contact’s tasks are created or updated.
Actions: POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, DELETE /contacts/:contactId/tasks/:taskId.
See endpoints: POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId, title, status
No code required to sync basic contact data between LeadCars and your CRM.
Automations and workflows can run without custom development.
Real-time updates reduce manual data entry and improve responsiveness.
This section defines core terms and processes used when integrating LeadCars with the Contacts API.
A person stored in the Contacts list with contact details and activity history.
A defined URL and HTTP method used to access or modify data in the API.
The standard authorization protocol used to obtain access tokens for API calls.
Process of proving identity to securely access API resources.
Configure a flow that creates a new contact in Contacts API when LeadCars captures a new lead, ensuring no data is lost.
When a task is updated in Contacts API, push a notification to LeadCars to keep the sales team aligned on next steps.
Pull notes from Contacts API into LeadCars to provide contextual information for each contact during outreach.
Obtain client credentials in LeadCars and authorize the app to access Contacts API.
Select the endpoints you need (e.g., GET /contacts/:contactId, POST /contacts/).
Run tests, map fields, and deploy to live to start syncing data.
With the Contacts API in LeadCars, you can access core contact data, including names, emails, phone numbers, company associations, tasks, notes, and activity history. This enables rich context for sales outreach and automation. You can also fetch related data like tasks and notes for deeper insights. For most flows, start by retrieving a contact with GET /contacts/:contactId to pull profile details, then pull associated tasks with GET /contacts/:contactId/tasks and notes with GET /contacts/:contactId/notes to build a complete picture.
Authentication uses OAuth 2.0. In LeadCars, obtain client credentials, authorize the app, and receive an access token. Include the token as a Bearer token in each request header. Refresh tokens before expiry to maintain seamless access. Store credentials securely and rotate them regularly to protect data integrity and comply with security best practices.
Commonly used endpoints include GET /contacts/:contactId for individual profiles, GET /contacts/ for listings, and GET /contacts/:contactId/tasks for task tracking. For tasks management, POST /contacts/:contactId/tasks creates a new task, while PUT /contacts/:contactId/tasks/:taskId updates status or details, and DELETE removes a task.
No code is required for basic data synchronization using prebuilt connectors and webhooks. However, depending on your use case, you may implement custom field mappings and conditional logic. If you need complex workflows, a developer can extend the integration using the provided endpoints.
Yes. You can fetch a contact’s tasks and notes in separate calls within a single workflow. Combine GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes in sequence to assemble a complete view for each contact. For efficiency, batch requests where supported and paginate results to manage data volumes.
Token refresh is handled via OAuth 2.0 flow. When a token expires, use the refresh_token to obtain a new access token without requiring user intervention. Implement automated refresh in your integration to avoid downtime.
API rate limits vary by plan. Refer to your API documentation for quotas and backoff guidance. To optimize performance, cache non-changing data, paginate large result sets, and stagger requests during peak times.
Due to high volume, we will be upgrading our server soon!
