NSU and TID are payment data that remain stored on the Orders module. This information is required for queries on the operator or payment gateway, for example. The definitions of each data item are given below.

• NSU: Unique sequence number is the identification number of a sales transaction using cards. It is attributed to each tax document issued.
• TID: Transaction ID is an identification (or authorization) number of the e-commerce transaction at the operator. This code is not generated in VTEX, but is sent by the operator at the time of authorization. That is, VTEX sends the order data and the gateway or the operator returns the TID.

This information is notified to VTEX during the transactions and organized for a simple view in + information in the details of the order.
