Post Error Handling Acknowledgement

[HarishDe]

Hello Everyone 

While trying to update a request in Workfront , I may either get a success or a Failure. 
After Success I can call a HTTP module to send the success Acknowledgement. 

However in case of failure I am not able to send the Failure acknowledgement. The Scenario stops at the WF module. 
Even if i add a Error handler, it doesn't allow me to add subsequent modules to get the error. 

Can anyone suggest the way to achieve this ?

Harish,

What I do in cases like this is using the filters to do my error handling so that I can send a note.  As example, I'll have a router from my module, then based on the bundles, if there were successful bundles route them to the http module, if there were error where no bundles happen, route the other path and give me a note as to what happened
