We are using the Authorize.net in our program to make the payment. We need following clarification to enhance our feature to users.
1) Currently we created account and supporting only USD currency. Is it possible to support multiple currencies in same account? If yes could you please share the details/blog how to implement that.
2) We are implementing the iFrame Accept Hosted method (Previously used SIM method). Is it possible to control fields (We no need CVV field) and look & feel (like CSS style changes) in iFrame Accept hosted method? If yes could you please share the details/blog how to implement that.
3) Also in the iFrame accept hosted method the CVV field is not mandatory one. In this case, if the user is entering invalid CVV of valid credit card will the Authorize.net validate the CVV number of credit card?
