             $newTicket = $client->tickets()->create([
                 'subject'  => $subject,
                 'comment'  => [
                     'body' => $description
                 ],
                 'custom_fields'=>[

Custom fields should be passed as id,value pairs try using this for custom_fields. To get fields id you can go to ticket fields panel on zendesk or can use this api api/v2/ticket_fields.json

 'custom_fields'=>[
                     [
                         'id'=> '<email_field_id>', 
                         'value'=> $email
                     ],
                     [
                         'id'=> '<transaction_number_field_id>',
                         'value'=> $transactionNumber
                     ]
 ],
