I get this error whenever I try to curl this CureBit JSON:

JSON::ParserError (757: unexpected token at '{"referred"=>{"customer_id"=>"91", "email"=>"eee@eee.com"}, "referrer"=>{"customer_id"=>"9", "email"=>"aaa@aaa.com"}}'):
  app/controllers/referrals_controller.rb:5:in `create'
-----------------------------

When I change the JSON manually to this, the error no longer occurs:
{"referred":{"customer_id":"98", "email":"eee@eee.com"}, "referrer":{"customer_id":"9", "email":"aaa@aaa.com"}}

-----------------------------
Is there a way to do this automatically?
