Response

PAN's syntax
The PAN (or PAN number) is a ten-character long alpha-numeric unique identifier.
The first five characters are letters (in uppercase by default), followed by four numerals, and the last (tenth) character is a letter.

Failure Response:

JSON

{
	"is_success": true,
	"data": {
		"error": "PAN does not exist in the NSDL database."
	}
}

Failure Response for Demo PANs in Production:

JSON

{
    "is_success": false,
    "error": {
        "message": "NSDL returned error status code: -1",
        "code": "invoid_error",
        "details": {
            "error_data": {
                "response": "NSDL has sent a failure response.",
                "payload": {
                    "error": "NSDL returned error status code: -1"
                }
            }
        }
    }
}

If we enter a PAN which is not in the above format then it will throw an NSDL error.
