Getting the Outcome of the "start and wait for approval" Vs getting the Responses Comments of the "start and wait for approval". For the later, Power Automate will automatically add a "Apply to Each"

[johnjohn123]

I have the following "Start and wait for approval" step inside my automated flow:-

Then i wanted to send an email containing the Outcome of the "start and wait for approval" + the Comment added by the first user for the "start and wait for approval", as follow:-

But my question is why Power Automate will automatically add a "Apply to Each" when we try to reference the Responses Comments, while it will not do the same if we try to reference  the Outcome? do both need "Apply to each"? or both do not ? as they are the same context; one return the comment and the other represent the action taken (Proceed or Pending) in our case?? Any advice?

Thanks

Outcome is a comma delimited string of the approval results for each approver.  Responses is an array of objects that contain properties like the response and the comments.  When processing an array you need to use an Apply to Each.  But since Outcome is a string you can read it directly.  Outcome lets people get the basic result of an approval without an Apply to each loop.  If you need more details, like the comments, then you need the loop.

@Pstork1ok thanks.. this is a bit confusing.. on why some result are been represented as comma separated, while the other are represented as array...

Outcome and summary are about the only two outside the Responses array.  As I said they are there to make it easier to get the basic results.  For specific details you need to use a Loop with the array.
