I'm creating a policy for sending a string through RAW assertion to the backend server and receiving a response from the server.
The request string is fixed length but the length of response string is unpredictable.
I need to get each value from the response string's different part and transfer it to JSON format.
Response String = AA9567BS33411002AAGF1FFG
AA9567 = Company ID
BS33411 = Customer ID
002 = The amount of Txn
AAGF = First Txn amount
1FFG = Second Txn amount
I'll know the number of Txn from the position 13-15(started from 0) of the string, but I'll never know the number before receiving the string.
I have no idea how to design the policies.
Is there any suggestion or any assertion suit to do this?
