Access to Contacts API uses OAuth 2.0 with the scope set to contacts.readonly by default. Obtain access tokens, refresh tokens as needed, and verify a successful connection from Your App to ensure secure data access.
Configure Your App to accept OAuth tokens from GHL and securely store credentials. If your flow supports API keys, manage them with rotation and strict storage practices to protect sensitive data.
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: a contact is created or updated in GHL and the changes are pushed to Your App in real time.
Actions: create or update contact in Your App; attach tasks; add notes; schedule appointments as needed.
Example path: GET /contacts/:contactId
Key fields: contactId, name, email, phone, status, owner
Trigger: a task is created or updated for a contact in GHL
Actions: create, update, or complete tasks in Your App; sync due dates and priorities
Example path: POST /contacts/:contactId/tasks
Key fields: taskId, title, status, dueDate, priority
Trigger: notes or appointments are added or updated for a contact
Actions: create or update notes in Your App; schedule or modify appointments; fetch history
Example path: GET /contacts/:contactId/notes
Key fields: noteId, content, author, timestamp
Automate data synchronization across systems without writing custom code.
Build powerful workflows with clicks, not complex development.
Scale easily by reusing standard REST endpoints and triggers.
Key elements include endpoints, triggers, actions, and field mappings that enable consistent integrations and repeatable workflows.
Application Programming Interface — a set of rules that lets software apps communicate and share data.
OAuth 2.0 is an authorization framework that grants limited access tokens to apps without exposing user credentials.
A callback mechanism where one app notifies another in real time via an HTTP request when an event occurs.
A specific URL in an API that performs a defined action or returns a resource.
Consolidate contact data from GHL into Your App to create a single source of truth for your team.
Use triggers to automatically create tasks and reminders when notes are added or due dates approach.
Guide new users with onboarding tasks and notes that surface at key moments in their journey.
Register your app with GHL and obtain OAuth client credentials; set the redirect URI and required scopes.
Choose endpoints such as /contacts and map fields like name, email, and id to your app data model.
Run test calls, verify data integrity, resolve mapping issues, and deploy to production with monitoring.
Access control defaults to read-only when starting a new integration, but you can request write access where supported. Always follow the principle of least privilege and grant only the scopes you need. When writing data, ensure proper validation and error handling to prevent data corruption.
Endpoints available vary by plan and environment. In general you can access common resources for contacts, tasks, notes, and appointments. Refer to the endpoint list in your integration console for current availability and any feature flags.
Authenticate via OAuth 2.0 and obtain access tokens for each session. Tokens should be refreshed before expiry, and securely stored. Use the refresh token flow to maintain a seamless connection without requiring user interaction.
Yes. You can create and update contacts, tasks, and notes from Your App by using the corresponding endpoints and proper authentication. Implement validation and conflict handling to keep data consistent across systems.
Errors are returned as standard HTTP status codes with a descriptive message. Rate limits are indicated via headers and retry guidance is provided in the response body. Implement exponential backoff to handle transient errors gracefully.
Required fields for creating a contact typically include at minimum a name and a unique identifier (contactId). Depending on your workflow, email and phone may be required for certain validations or communications.
Logs and histories can be viewed in the integration dashboard or via API-provided audit endpoints. Use these to monitor calls, successes, failures, and data changes over time.
Due to high volume, we will be upgrading our server soon!
