Authenticate calls to the Contacts API using OAuth 2.0 with the required scope: contacts.readonly. Include a valid access token in the Authorization header for each request.
To authorize GrazeCart with the Contacts API, generate an OAuth token via the GrazeCart developer portal and attach it to requests as Bearer tokens. Rotate credentials regularly and scope access to contacts.readonly.
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: New contact creation in GrazeCart should create or sync the corresponding contact in the Contacts API.
Actions: Map core contact fields (name, email, phone), attach initial tasks, and link notes as context.
GET /contacts/:contactId
Key fields: contactId, name, email, phone
Trigger: When a task is updated in Contacts API, reflect changes in GrazeCart.
Actions: Create, update, and complete tasks; sync task status and due dates.
GET /contacts/:contactId/tasks
Key fields: taskId, status, title, dueDate
Trigger: Note or appointment added in Contacts API updates GrazeCart records.
Actions: Create notes and schedule appointments within GrazeCart linked to the contact.
GET /contacts/:contactId/notes
Note fields: id, content; Appointment fields: id, time, location
Fast setup with no-code automations: connect GrazeCart to Contacts API using pre-built templates.
Real-time data visibility: view updated contact data across apps instantly.
Improved collaboration: keep notes, tasks, and appointments synchronized without manual data entry.
This section defines key elements and processes: endpoints, authentication, data mapping, and common workflows between GrazeCart and the GHL Contacts API.
Definition: A specific URL path and HTTP method used to interact with the GHL Contacts API.
Definition: An authorization framework that issues access tokens to authorize API requests securely.
Definition: A string token that verifies identity and permissions for API calls.
Definition: The set of permissions granted to an access token (e.g., readonly).
Use new contact data to automatically create onboarding tasks and checklists in GrazeCart for faster activation.
Trigger reminders in GrazeCart when contact details or due dates are updated in the API.
Aggregate data from contacts, tasks, notes, and appointments for cross-functional insights.
Obtain OAuth tokens from GrazeCart and grant Contacts API access with scope ‘contacts.readonly’.
Choose endpoints (e.g., GET /contacts/:contactId, GET /contacts/:contactId/tasks) and map fields to GrazeCart fields.
Run tests in a sandbox, validate data flow, and deploy to production with monitoring.
No coding is required for basic integration. GrazeCart provides OAuth-based authentication and pre-built endpoints that you can call from any standard HTTP client. For more complex automations, you can use low-code tools or integrations to map fields and trigger actions without writing extensive code.
The read-only scope you need is contacts.readonly. Your access token must include this scope to retrieve contact data. In some setups, you may request additional scopes only if you require write access, which should be carefully managed. Keep tokens secure and rotate credentials regularly to maintain a secure connection.
This guide focuses on read-only access. Writing data back to GrazeCart from the Contacts API requires additional permissions and careful governance. If enabled, you would use scopes like contacts.write in combination with proper auditing. Always validate write readiness in a staging environment before going live.
Access tokens typically have expiration. Use the refresh token flow to obtain new access tokens without user intervention. Store tokens securely, implement automatic token refresh in your integration, and monitor token expiry to prevent disruption.
Commonly used endpoints include GET /contacts/:contactId to fetch a contact, and GET /contacts/:contactId/tasks to pull related tasks. For creating or updating data, POST /contacts/ or PUT /contacts/:contactId are used in setups that require write access. Choose endpoints that match your workflow and map fields to GrazeCart data structures.
There are rate limits on API calls. If you hit the limit, implement retry logic with exponential backoff and consider batching requests where possible. Consult the API docs for current limits and best practices to avoid throttling.
API documentation is available in the GrazeCart developer portal and the GHL API docs section. If you need support, contact the developer relations team or use the community forums for guides and examples. You can also open a support ticket through your GrazeCart account for personalized help.
Due to high volume, we will be upgrading our server soon!
