title: Masspay can not pay
body: <p>I receive the following error when I try to send money using masspay api through my site backend : <strong>"The input to the masspay server is incorrect. Please make sure that you are using a correctly formatted input. , Masspay not complete"</strong></p>
  
  <p>The result is that money don't transfer.</p>
  
  <p>This only happens when the amount has decimal digits. For instance 4.25€. It's NOT happening when I try to send non decimal amounts, for instance 10€, 20€ or other.</p>
  
  <p>What is happening?</p>
  
  <p>Thanks</p>
