title: Authorize.net: How to validate the credit card using "AUTH_ONLY"?
body: <p>I am using the authorize.net AIM Module transaction. Now I want to validate the CreditCard Number , Expiry Date and CCV Number with out charging the credit card. </p>
  
  <p>I used <strong>AUTH_ONLY</strong> method in x_type and passed amount as "0.00". It didnt worked. SO I changed the amount to "0.01". It worked. As per my assumption "0.01" charged from the card and saw the transaction in the report, Without charging I need to validate the card. As per their documentation It will not charge. Buts its charging. </p>
  
  <p>Can any one help me on this ? Also please explain the difference between <strong>AUTH_ONLY</strong> and <strong>AUTH_CAPTURE</strong></p>
