Let me know if I do something wrong in this.

On sandbox it is printing below:
(
[message] => Invalid response
[status] => ERROR
[responsecode] =>
[auth_code] =>
[trans_id] =>
[ref_id] => 1549025223
)

On live it it printing below:
(
[message] => Invalid response
[status] => ERROR
[responsecode] => 4
[auth_code] => 937176
[trans_id] => xxxxxxxxxx
[ref_id] => xxxxxxxx
)

Any help or suggession will be highly approciated.

Thanks in advance.
