How to make the post request in BOX API using LWP::UserAgent? - perl

Question

I have tried the following code
my $url = "https://api.box.com/2.0/users/";
use strict;
use warnings;
use LWP::UserAgent;
use HTTP::Request::Common qw{ POST };
use CGI;
my $ua = LWP::UserAgent->new();
my $request = POST( $url, [ 'name' => 'mkhun', 'is_platform_access_only' => 'true',"Authorization" => "Bearer <ACC TOK>" ] );
my $content = $ua->request($request)->as_string();
my $cgi = CGI->new();
print $cgi->header(), $content;
The above code always give the 400 error. And throwing the
{"type":"error","status":400,"code":"bad_request","context_info":{"errors":[{"reason":"invalid_parameter","name":"entity-body","message":"Invalid value 'is_platform_access_only=true&Authorization=Bearer+WcpZasitJWVDQ87Vs1OB9dQedRVyOrs6&name=mkhun'. Entity body should be a correctly nested resource attribute name\/value pair"}]},
I don't know what is the issue. The same thing with Linux curl is working.
curl https://api.box.com/2.0/users \
-H "Authorization: Bearer <TOKEN>" \
-d '{"name": "Ned Stark", "is_platform_access_only": true}' \
-X POST

The Box API documentation says:
Both request body data and response data are formatted as JSON.
Your code is sending form-encoded data instead.
Also, it looks like Authorization is supposed to be an HTTP header, not a form field.
Try this instead:
use strict;
use warnings;
use LWP::UserAgent;
use JSON::PP;
my $url = "https://api.box.com/2.0/users/";
my $payload = {
name => 'mkhun',
is_platform_access_only => \1,
};
my $ua = LWP::UserAgent->new;
my $response = $ua->post(
$url,
Authorization => 'Bearer <TOKEN>',
Content => encode_json($payload),
);
