Post the picture of the workflow from where you are trying to extracting the information
I think you have a similar requirement like here How to extract specific data from a JSON payload using SelectToken? - #6 by marian.platonov
Should i have to put something like this DeserializedArray.SelectToken(“[0].OrderHeaderKey”).ToString ?
this is the response from Http request …after deserialising json array i get the about output . From that i need orderheaderkey
You can try with Regex expression
System.Text.RegularExpressions.Regex.Match(YourString,"(?<=OrderHeaderKey”:\s“)\d+").Tostring
Check out the thread for reference

From your sample we do see an array with only 1 item. So we can do:
Line2 - e.g. for a looping, when more items are present
We recommend to prefer JSON processing for JSON data over String processing e.g. Regex
DeserialiseJsonArrayOutput(0)(“OrderHeaderKey”).tostring worked
