title: Improved security using Customers API with Transaction API?
body: <p>I'm currently using the transaction api to create simple, single charges and refunds. We won't be needed recurring billing.</p>
  
  <p>Is there any security benefit to creating a customer profile when using the transaction API?</p>
  
  <p>Other payment providers will look for a datakey or client payment info first on its end rather than accepting post requests with sensitive information.</p>
