in reply to retrieving data from a json response

If it's encoded using UTF-8,

use JSON::XS qw( decode_json ); my $data = decode_json($json);

If the character encoding has already been removed,

use JSON::XS qw( ); my $data = JSON::XS->new->decode($json);

Then,

say $data->{d}{response}[0]{ptoFpngTransactionBundle}{bundleProcessSta +tus};
