Hello,

I used service merchant plugin in my application. using “paypal getway”  
it works fine.

But when i tried [authorize.net](http://authorize.net) as a getway, it dose not work. It gives  
error

StandardError in SubscriptionsController#subscribe  
Recurring payment creation error: User authentication failed due to  
invalid authentication values.

When i debug the code I think one file (i.e may be  
authorizenet\_extension.rb) is missing in

“vendor\plugins\service\_merchant\recurring\_billing\lib\am\_extensions”

There is only paypal\_extension.rb is present for paypal getway. but not  
like “authorize.net\_extension.rb” for [authorize.net](http://authorize.net) getway.

Am I right?

If the authorizenet\_extension.rb is missing, please tell me whether  
should I get that file.  
Please guide me where I’m doing wrong?
