> Changelog for January 09, 2026

## ✨ New Features

* **Transaction Detail by ID:** Launched a new API to fetch specific transaction details using a `transaction_id`.
* **Virtual Account Transaction History:** Developers can now retrieve transaction lists associated with a specific `virtual_account_id`.
* **Batch Item Status Webhook:** Introduced the `batch.transaction.item.status` webhook to track items as they enter the processing queue.

## 🛠️ Improvements

* **Immediate Batch IDs:** The `transaction_id` is now available in the Batch Details response immediately following a Batch Create call.
* **Enhanced Conflict Responses:** When a duplicate beneficiary is detected, the `409 Conflict` error now returns the existing `beneficiary_id`.

## 🐞 Bug Fixes

* **Strict Country Code Validation:** Added mandatory ISO alpha-3 validation for beneficiary country codes.
