To access the GHL Contacts API, grant the app the scope contacts.readonly and, if needed, additional write permissions as you progress. Use OAuth or API keys as supported.
In the freee app, generate API credentials and connect them to GHL with the allocated scopes. Ensure the scopes match the read and write requirements for contacts, tasks, and notes.
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 contact is created or updated in freee
Actions: upsert contact in GHL, mapping core fields like email, name, phone
Method/Path: POST /contacts/ to create, or PUT /contacts/:contactId to update
Key fields: email, firstName, lastName, externalId
Trigger: when a task is created or updated for a contact in freee
Actions: create or update a corresponding task in GHL; sync due date and status
Method/Path: POST /contacts/:contactId/tasks
Key fields: contactId, taskId, subject
Trigger: when a note is added to a contact in freee
Actions: create notes in GHL with content and timestamps
Method/Path: POST /contacts/:contactId/notes
Key fields: contactId, noteId, content
Automate data flow without writing code
Keep contacts, tasks, and notes in sync across systems
Improve reporting with centralized data in GHL
Key concepts include endpoints, triggers, actions, data mapping, and authentication flows that connect freee to GHL
A URL and HTTP method that lets a program access a resource in an API
A standard for secure delegated authorization between apps
A real time event notification that pushes data to another system
JavaScript Object Notation, a lightweight data interchange format
Automatically fill missing contact fields in GHL from freee records when syncing.
Turn important freee events into tasks in GHL to keep teams aligned.
Sync notes to GHL to provide context to sales and support.
Obtain freee API credentials and authorize the GHL integration with the required scopes like contacts.readonly.
Map fields between freee and GHL for contacts, tasks, and notes to ensure accurate sync.
Run end-to-end tests and monitor logs; set error handling and retries.
You can use OAuth for secure access and API keys where supported. Start with read-only access to validate data and then request higher privileges for write operations like creating or updating contacts. OAuth is recommended for production workflows, while API keys may be suitable for agent-level or internal integrations. Always follow the principle of least privilege.
For basic sync you will typically use GET endpoints to pull contact records and related data such as tasks and notes. When writing back, POST and PUT endpoints are used to create or update contacts, tasks, and notes. The ENDPOINTLIST section shows the exact paths you will map in your workflow.
No code is required if you use a no-code integration layer or automation platform. You can configure triggers, actions, and field mappings visually. If you need advanced logic, you can add minimal scripting, but most scenarios are achievable with out-of-the-box components.
Data mapping involves aligning core fields such as email, name, phone for contacts; subject, dueDate, and status for tasks; and content for notes. Maintain consistency by using external IDs to prevent duplicates and handle conflicts with upsert operations.
Rate limits depend on your GHL plan and the endpoints used. Implement exponential backoff and retries. Monitor responses for error codes, and log failures for troubleshooting. Consider batching where supported to reduce call volume.
Yes, you can test in a sandbox or development environment before going live. Use test credentials, simulate real data, and verify each flow end-to-end. After validation, promote changes to production with proper monitoring.
View logs and error messages in the integration dashboard or your automation platform. Use the endpoint response details to diagnose issues, check rate limits, and confirm successful data synchronization.
Due to high volume, we will be upgrading our server soon!
