restrict bounce back during jira automation

[gayan ganepola]

we are in the process of integrating Jira and fresh service. by Jira automation 

1. Once I update a comment the same comment is passing to fresh service.

2. likewise, if fresh service updates something it should update the Jira ticket. 

in situation  2 is there any way of trigger back and send the same comment back to freshservice?

And how can I restrict this in automation?

is there a way of finding out whether the update is done by rest API or by user
