API Flow : how to manage several types of response depending on the success or failure of the call?

Denis MARETTE

Hello,

There's one point I don't understand in the logic of building an API flow at the level of the properties of this flow.

In the Response tab, I understood that we were modeling what our api flow should return as the final result to the calling application.
But how do you configure 2 responses?

One when everything goes well (Code: 200) and another when things go wrong (Code: 400 for example).
I'm sure there's a trick I'm missing

Denis,

there is indeed a way. What you provide on the start/end point is the default output and result code as you indicated.  But you can also add (as last step) a filter building block. A filter has an own exit of the flow. On this exit you can provide a response and a status code.

If you capture the different outcomes of the API calls executed in your flow then based on that information you can decide to exit via the filter or the "normal" way. 

In Filter Parameters  you could have  EM  as name and this as value ${MMS235OK.ErrMSG}

Then in Conditions  if ($.EM == 'OK' )  'Yes'; else 'No'

Then with OK -> Yes the normal exit and with No -> a (functional) error message from a previous API call -> exit via filter 

Hope this makes sense and helps.
