How do I Refund Credit Card using Authorize.net?

[abhilash08]

Hi Friends,

Am in critical situation. I want to refund a credit card. Am using Authorize.net for credit card transactions. Our site is in PHP.
How can i implement this with my site?
automated credit card refunding. we have all information's about user.
our site is online shopping. Any "API" for this?
All of them telling this is possible. Any one have any idea please help me.

It would all depend on what cart you have/using. Otherwise simply login to your authorize.net account and refund the transaction.

Welcome aboard abhilash08, I'm pretty familiar with authorize.net, and contractor is correct. For ordinary authorizations/purchases, you have to do this manually through the A.N. merchant interface. If you have ARB set up (Automatic Recurring Billing) you can cancel/refund billings, but this only works on transactions that were created with ARB.

Now we refunding the credit card using A.N merchant interface.
we are using our own shopping cart. we dont have ARB set up.
Also i want to know about AIM implementation?
They discussed that the transaction type will be "CREDIT" if i change the • x_Type (Credit) is it working ..?
how i implement this?

authorize.net's developer website has excellent documentation for the API. Issuing a refund is as easy as setting up a charge, but there is one caveat: you have to know the transaction number of the original charge you want to refund. You must have stored it when you did the initial charge. That transaction number must be submitted with the refund request. You cannot just change the transaction type to CREDIT.

Refund a credit card is very simple. i have worked successfully.
just change x_type =>"CREDIT". if we r using authorize.net for credit card processing. use AIM for refunding. implement this API with our site we can refund a credit with one click. Thanks for all professionals they give me good advise.

Thanks
