trigger email when exception raises

Hi,

The interface that I'm working on is MQ -> PI <-> SOAP. Between MQ and PI it's Asynchronous, we are only reading the messages from MQ.

But on the receiver side between PI and SOAP it's synchronous. Please see it below:

When the response from SOAP is something else other than the 'Success', I need to trigger an email with the response as the email body. Can you please let me know how can I achieve this?

Thanks,

Sai
