To improve the external integration capabilities of the VM API, this release includes the following updates:

Added

Added support for a custom client request identifier. Developers can pass X-Client-Request-Id in the request header for request tracking, duplicate request identification, and log correlation. If this header is provided in the request, the same X-Client-Request-Id will also be returned in the response header.

Added a new card flow query API: /getCardFlow.

Updated

The /getProductCode API response now includes a new field: remaining_open_card_num, which indicates the remaining number of cards that can be issued under the current product code.
