Architecture

Unidirectional Communication

The bulk messages are delivered by the issuer to SIX via the MQ channel, which is strictly one-way. No direct response is expected or received through this channel. However, the bulk operations will trigger card lifecycle events which the issuer can receive as push notification via debiX PUSH.

For direct two-way interactions or follow-up actions, issuers should use the debiX API.

MQ Setup

All bulk messages are delivered through a single queue to SIX.
