I am trying do a post request using REST::Client and keep getting 400 error. Here is what the client is expecting

Post: /api/m1/token

Hots: https://api.xxx.com

Content-Type: application/x-www-form-urlencoded

grant=client_credentials&partner={partner}&client={client}&secret={secret}

based on the above information what am I doing wrong. Here is the code 

use Data::Dumper;
use REST::Client;

sub generate {
  my $tokenURI = 'https://api.xxx.com/api/m1/token';
  displayMsg( "Establishing connection................"); 
  my %json_body = (grant => 'client_credentials',
                      partner => ‘dfjkdjfdkdjkdkdjfdk’,
                      client =>  'dkfjdlfjdlfkjlj',
                      client => 'dfkljflsfjlajflafjlsdkfjdskl=',  # ne
+ed encoding that is = will be %3D
        );     
  $restClient->addHeader("Content-Type", "application/x-www-form-urlen
+coded");
  my $bodyData = encode_json(\%json_body);
  $restClient->POST($tokenURI, $bodyData);         
   print Dumper($restClient);                   
                                   
  if ($restClient->responseCode() eq '200') {
  displayMsg ("Sucessfull ");
   my $token =  decode_json($restClient->responseContent());   
   my $tokenAccess = $token->{'access_token'};
   my $tokenType = $token->{'token_type'};
   return  $tokenType.' '.$tokenAccess;       
     } 
  else {
   displayMsg ( "Failed .");
   displayMsg( 'Response status: ' . $restClient->responseCode());
   foreach ( $restClient->responseHeaders() ) {
   print 'Header: ' . $_ . '=' . $restClient->responseHeader($_) . "\n
+";
       }   
      exit 1;
      }
   }
