When is the Handler called in relation to the message?

The Handler is called after the message has been stored, which is why this choice is the correct one. In the context of the Avaloq Message Interface (AMI), the process surrounding message handling typically follows a specific sequence: messages are first received, then they are parsed, and subsequently, they may undergo transformation before finally being stored for further processing.

When the message is stored, it is then that the Handler is invoked. This allows for any necessary actions to be taken on the already-stored message, such as logging, further processing, or triggering other workflows based on the content of the message. This sequence ensures that the system efficiently manages the lifecycle of the message from receipt to action, making it crucial that the handling occurs after the storage phase.

Understanding this sequence is vital for designing and implementing effective message handling workflows within the Avaloq system, ensuring that all steps are correctly configured to respond to specific messages as intended.
