Hi, actually I tried the request you shared long ago already and it does not work as the square brackets ([ ]) are not valid in Appian for JSON and therefore I changed it to curly brackets. 
 We get the following error if we use square brackets in Appian integration: 
 
 I am grateful for your response, however, I have figured a solution already as well. 
 If we use a Rule Input (let's say "value") of type TEXT and then pass the exact same JSON request body with square brackets (the one you sent) as Rule Input's value and use the Rule Input in the body (i.e. ri!value) then it works fine: 
 
 I had a conversation over online call with someone from Appian Support and they have confirmed that yes the square brackets won't work and also agrees that this is a peculiar thing that it somehow works fine when same request is passed as Rule Input of type TEXT.
