Open Batch API Fixed for Transact API

Previously, attempting to perform an Open Batch API call through the iPOS Transact API for Tap on Phone TPN (Version 2) resulted in an error. This issue occurred because the request was always sent using v1, regardless of the TPN version.

With this update, the system now verifies the TPN version before initiating the Open Batch API call:

• TPN v1 → Uses v1/open-batch-test

• TPN v2 → Uses v2/open-batch-test

This ensures that Open Batch requests are processed correctly based on the TPN version, preventing errors and improving transaction handling.
