Hi, when trying to access nested elements of data structures using key "paths" as you have, I usually turn to a JSON pointer. I find Mojo::JSON::Pointer easiest to use. In the following demonstration I am being lazy and returning your Dumper dump from a sub and then converting it back to JSON. If you are using LWP::UserAgent's decoded_content() you will already have the structure in $data below.

use v5.014;
use JSON;
use Mojo::JSON::Pointer;

# reconstructing a JSON response from your Dump
my $json = to_json( get_response() ); # your client request gets this

# converting your API response to a Perl struct
my $data = from_json( $json ); # your client should provide this

# converting the elements to JSON pointer paths
my @elements = map {s!\.!/!gr} (qw/ userName displayName meta.created 
+/);

for my $item ( @{ $data->{Resources} } ) {
    my $pointer = Mojo::JSON::Pointer->new( $item );

    foreach my $element (@elements) {
        say "$element: " . $pointer->get('/' . $element);
    }

    say '';
}

sub get_response {
    return {
       'Resources' => [{
                             'displayName' => 'User 1',
                             'userName' => 'user1@test.com',
                             'id' => '1234567',
                             'meta' => {
                                         'created' => '2018-04-16T11:5
+7:19.376Z'
                                       }
                           },
                           {
                             'displayName' => 'User 2',
                             'userName' => 'user2@test.com',
                             'id' => '1234568',
                             'meta' => {
                                         'created' => '2018-04-16T11:5
+9:27.111Z'
                                       }
                           },
                           {
                             'displayName' => 'User 3',
                             'userName' => 'user3@test.com',
                             'id' => '12345679',
                             'meta' => {
                                         'created' => '2018-11-21T14:4
+9:33.821Z'
                                       }
                           },
                         ],
          'totalResults' => 3,
          'itemsPerPage' => 50,
          'startIndex' => 1,
          'schemas' => [
                         'urn:ietf:params:scim:api:messages:2.0:ListRe
+sponse'
                       ]
    };
}
