Authenticate requests to the GHL Contacts API using the client credentials and the defined scope. In this page we emphasize the required scope contacts.readonly and how to refresh tokens safely.
In CS-Cart set up the app credentials, store client id and client secret securely, and map the CS-Cart fields to GHL fields for smooth data transfer.
GET /contacts/:contactId — Retrieve a single contact; GET /contacts/:contactId/tasks — List tasks for a contact; GET /contacts/:contactId/tasks/:taskId — Get a specific task; GET /contacts/:contactId/notes — List notes; GET /contacts/:contactId/notes/:id — Get a note; GET /contacts/:contactId/appointments — List appointments; GET /contacts/ — List all contacts; GET /contacts/business/:businessId — List contacts for a business; POST /contacts/ — Create a contact; PUT /contacts/:contactId — Update a contact; DELETE /contacts/:contactId — Delete a contact; POST /contacts/:contactId/tasks — Create a task; PUT /contacts/:contactId/tasks/:taskId — Update a task; PUT /contacts/:contactId/tasks/:taskId/completed — Mark a task complete; DELETE /contacts/:contactId/tasks/:taskId — Delete a task; POST /contacts/:contactId/tags — Add a tag to a contact.
Trigger when a contact is accessed or when a contactId is available in CS-Cart
Actions include retrieving the contact, listing its tasks, and fetching a specific task if needed
GET /contacts/:contactId
Key fields: id, email, firstName, lastName, phone
Trigger when notes are added or updated in CS-Cart for a contact
Actions: GET /contacts/:contactId/notes, GET /contacts/:contactId/notes/:id
GET /contacts/:contactId/notes
Key fields: contactId, id, note, createdAt
Trigger when a contact is created or updated in CS-Cart
Actions: POST /contacts/, PUT /contacts/:contactId, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId
POST /contacts/
Key fields: id, email, firstName, lastName, status
No code setup lets you connect CS-Cart to the GHL Contacts API with a few clicks.
Automations can be built to respond to contact changes without writing code.
Unified data enables better segmentation and reporting in CS-Cart and GHL.
Learn about core elements like endpoints, triggers, actions, and how data maps between CS-Cart and GHL
A set of rules and tools that lets CS-Cart talk to the GHL system
A process to verify identity and grant access to API resources
The URL path used to perform a specific operation in the API
A real-time notification that CS-Cart can receive from GHL when data changes
When a new contact is created in CS-Cart, push it to GHL and create a welcome task automatically
Share CS-Cart notes with GHL notes and attach to the contact record
Use tags in CS-Cart to segment in GHL and trigger targeted automations
Obtain client id, client secret and define the scope for read-only access
Map CS-Cart fields to GHL fields and set up webhook notifications
Run tests, verify data flows, monitor logs, and deploy to production
Yes, the integration uses secure tokens and HTTPS for all API calls. You should store credentials securely and rotate them periodically. The scope for read-only access helps protect customer data while enabling essential retrieval of contacts, tasks, and notes. In practice, start with a minimal scope and expand as your workflow requires.
Some setup can be done with no code using standard connectors and webhooks. More complex scenarios may require light scripting or a middleware tool, but many common flows are achievable with no code. We provide templates and mappings to simplify the process.
For basic syncing you will use endpoints for retrieving contacts, tasks, and notes. You may also need the endpoints to list all contacts and to create or update a contact as needed. The exact endpoints depend on your workflow.
Yes, you can propagate updates from GHL back to CS-Cart by using the update endpoints and webhooks. Bidirectional sync requires careful mapping and conflict resolution rules.
Common errors include invalid credentials, insufficient scope, and rate limits. Implement token refresh logic and retries with backoff. Check endpoint paths and ensure correct IDs are used.
Map fields such as contact name, email, phone, and notes to corresponding fields in CS-Cart. Use clear data types and normalization to avoid mismatches.
Monitor the integration with API dashboards, logs, and alerts. Set up automated notifications for failures and latency.
Due to high volume, we will be upgrading our server soon!
