The following characters are considered special characters in JSON:
- Double quotes (“)
- Backslash ()
- Newline (\n)
- Carriage return (\r)
- Tab (\t)
- Backspace (\b)
- Form feed (\f)
Important: By default, GLU.Engine will not make changes to the specified special characters during the integration flow.
Unescape Json Special Characters
GLU.engine provides the capability to unescape these characters. The process of unescaping JSON characters is the reverse of the escaping process, and it involves converting the encoded special characters back into their original form. This allows the JSON data to be properly interpreted and used by applications that receive it.
To perform the unescape operation, choose “Unescape Json” from the Decoder dropdown menu.

Example
Original JSON payload:
{
\"TRANSACTION_ID\":\"5930551\"
}
Unescaped JSON payload:
{
"TRANSACTION_ID":"5930551"
}
