Rest json response find correlation id

[Training]

Im creating incident to third party using POST REST. Then doing GET method to get number/sysid of that incident so I can set it as correlation id in my instance.

Using GET I'm getting response -

Transactions[

..

.

body{

Incident 1 In encrypted base 64

}

body{

Incident 2 In encrypted base 64

}

So on

How can I iterate through this response array and then decode it to set correlation id?

Please help.

I cannot define jsonString cause it is dynamic data and will change in each GET call.

Sorry, not working, i would not be able to define response strong cause it may contain multiple records.. so i think i need to decrypt body using base64 decide function and then iterate through it to match my incident number using gliderecord to incident table.

If i get to some help on it, it will be grateful, thanks.

We are not really sure what exactly you are writing.
