The StoreID request parameter is marked as optional in the «API Integration Guide(Nov 2017)» → «API Reference» → «Request Message» documentation section, so I do not understand when the Magento module should or should not pass it to AlphaCommerceHub:
| Parameter Name | Type | Format | Mandatory | Description |
|---|---|---|---|---|
| StoreID | Alpha | O | Store ID assigned by APC (primarily used in card present transactions) |
