Connecting DSFinV‑K with SIGN DE

This page explains the connection between DSFinV‑K and SIGN DE.

Security

The security object establishes a connection between the DSFinV‑K and the signature data of SIGN DE.

Within the endpoint Insert a cash point closing request body, transactions[].head.tx_id and security.tss_tx_id corresponding to the tx_id field from SIGN DE are used.

Transactions that could not be signed via SIGN DE still need to be recorded via DSFinV‑K in the Cash Point Closing. For this purpose, please use the transactions[].security.error_message field with the corresponding error message instead of the tss_tx_id field. You need to generate a new UUID for the transaction ID in this case.
