Authenticate requests to the Contacts API using OAuth 2.0 with scopes covering contacts.readonly (and contacts.write for create, update, or delete operations). Include a valid access token in the Authorization header and rotate tokens securely. Use a test environment during initial setup.
Cin7 Core Inventory authenticates to the GHL Contacts API by exchanging credentials for a scoped access token. Store refresh tokens securely and follow least-privilege access when assigning scopes.
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 Cin7 Core Inventory to fetch the latest data from GET /contacts/:contactId.
Actions include calling GET /contacts/:contactId to pull the latest profile, and loading related notes and tasks via GET /contacts/:contactId/notes and GET /contacts/:contactId/tasks.
GET /contacts/:contactId
contactId, name, email, phone, tags
When Cin7 Core Inventory applies business rules, create or update tags in the Contacts API.
Actions: POST /contacts/:contactId/tags to assign tags that segment customers for marketing or support routing.
POST /contacts/:contactId/tags
contactId, tags
Schedule a nightly sync to reconcile records between Cin7 Core Inventory and the Contacts API.
Actions: GET /contacts/ to pull all contacts, PUT /contacts/:contactId to update fields, GET /contacts/business/:businessId to verify related data.
GET /contacts/
contactId, businessId, status, lastUpdated
Automate contact syncing without custom development, reducing manual data entry and errors.
Live data updates keep sales, support, and fulfillment teams aligned in real time.
Centralized data improves reporting, forecasting, and decision making across tools.
This glossary defines common terms and processes you’ll encounter when integrating the GHL Contacts API with Cin7 Core Inventory.
A person or organization profile stored in the Contacts API, including identifiers and linked records like notes, tasks, and tags.
A specific URL path in the API that performs a defined operation, such as retrieving or updating a contact.
The process of proving identity to access the API, typically via OAuth 2.0 tokens or API keys with scoped access.
The ongoing process of keeping information consistent between Cin7 Core Inventory and the GHL Contacts API.
Create a single customer profile in Cin7 Core Inventory by aggregating data from the Contacts API, including notes, tasks, and business associations.
Auto-tag contacts in the GHL API based on purchasing behavior and lifecycle stage observed in Cin7 Core Inventory.
A centralized dashboard that shows sync status, conflicts, and last-change timestamps across both systems.
Create an API key, configure OAuth 2.0 credentials, and grant the required scopes for both read and write access.
Set up GET, POST, PUT, and DELETE requests for contacts and related resources; configure trigger events for create/update.
Test data flows in a staging environment, validate mappings, then deploy to production with monitoring.
The integration supports OAuth 2.0 tokens and API keys. Use scoped access to limit permissions to what your workflow needs (e.g., read-only for reports, write for updates). Ensure tokens are stored securely and rotated regularly. If an API call fails, implement exponential backoff and retries.
Core endpoints for syncing include GET /contacts/:contactId, POST /contacts/, PUT /contacts/:contactId, GET /contacts/:contactId/tasks, and GET /contacts/:contactId/notes. These allow you to pull profiles, create or update contacts, and fetch related data for complete syncing.
Implement retries with backoff, log error details, and surface a clear error message in the UI. Use idempotent operations where possible (e.g., PUT rather than POST for updates).
Yes. No-code platforms and the Zapier app connector can orchestrate calls to the GHL Contacts API and Cin7 Core Inventory using authentication tokens and predefined triggers. Build simple workflows to sync fields without writing code.
By default, key fields such as contactId, name, email, and phone are synchronized. Depending on your mapping, additional fields may be included like tags, notes, and tasks. You can customize the field set in the integration configuration.
Use a staging environment to validate data flows. Create test contacts, simulate triggers, and verify that changes propagate correctly. Monitor logs and set up alerts for failures.
API rate limits vary by plan. Refer to the GHL and Cin7 API docs for current quotas and implement client-side throttling and retry strategies to stay within limits.
Due to high volume, we will be upgrading our server soon!
