Key Capabilities
Manage Complex Payment Flows
Write a script that validates sales by first checking the order details using `get_order_details`. After verification, you can then call `get_payment_details` to ensure the payment matched the sale amount. If those checks pass, your workflow can confidently proceed with creating a new transaction via `create_payment`, handling retries if necessary.
Inventory Check and Reporting
Build a nightly check to ensure you don't run out of stock. The `get_stock_count` tool retrieves the current count for any item ID. You can also use this server to pull all available items using `list_catalog` into your report, making sure the inventory data is accurate before deployment.
Consolidating Store Data
The `list_store_locations` tool lets you gather all site IDs in a single run. You can then feed these location IDs into `search_orders` to compile one master list of all recent transactions across your entire business. This helps Ops teams build full audit trails that cross multiple physical sites.
