Hi, 

I followed the example to use an iframe and was successfulll using my sandbox.

The iframe is posting the token to https://test.authorize.net/payment/payment

And I was gettgin the approval using 4111 1111 1111 1111  card.

We are now switching to our customer account wich is Production in TEST MODE. I already changed the environment to AuthorizeNet.Environment.PRODUCTION, and updated the LoginID and TransactionID and I am able to get the token to post. So the keys are right.

In the iframe I changed the URL to https://secure.authorize.net/payment/payment and it loads perfectly, but once I hit Pay the button changes to Processing... and stays that way forever. If I monitor the console eventually I get:

Response with status: 550 OK for URL: https://secure.authorize.net/Payment/Api.ashx

Is it even possible to get approved transactions in Production TEST MODE?

Is https://secure.authorize.net/payment/payment the right url?
