Hello,
I am just now testing REST API (9.3.3) with Postman.
I already can make some steps, it is however difficult to set the correct parameter form in Postman ...
If I guery the ticket with "/rest/api/latest/issue/10125", I see evreything I need.
If I try to change the "Summary" of the tickets, the "Post" Operation fails.

How can I correctly change the field values?
Thank you very much for a short confirmation.
Best regards
Istvan
