Hi

I am trying to get up and running using active merchant and have been  
following the article [here](http://www.actsasflinn.com/articles/2007/02/27/ruby-on-rails-credit-card-processing-with-active-merchant)

I have set up all of my sandbox accounts, downloaded the certificates  
and pulled in all of the login info supplied by the sandbox account but  
for some reason I keep getting “StandardError in  
OrderController#checkout - Username/Password is incorrect” … although  
I am pretty sure that is not the case.

My controller looks like this

* * *

class OrderController \< ApplicationController

def checkout  
creditcard = ActiveMerchant::Billing::CreditCard.new(  
:type =\> ‘visa’,  
:number =\> ‘the number supplied by paypal’,  
:month =\> 1,  
:year =\> 2010,  
:first\_name =\> ‘Test’,  
:last\_name =\> ‘User’  
)  
params = {  
:address =\> {  
:name =\> ‘Test User’,  
:address1 =\> ‘1 Main St’,  
:city =\> ‘San Jose’,  
:state =\> ‘CA’,  
:zip =\> ‘95131’,  
:country =\> ‘US’,  
:phone =\> ‘415-222-2222’  
},  
:ip =\> ‘127.0.0.1’  
}  
if creditcard.valid?  
# Create a gateway object to the Paypal service  
gateway =  
ActiveMerchant::Billing::PaypalGateway.new(:login =\>  
‘mysandboxAPIusername’, :password =\> ‘mysandboxAPIpassword’)

```
      # Authorize for 10 dollars (1000 cents)
      response = gateway.authorize(1000, creditcard, params)

      if response.success?
        # Capture the money right away
        gateway.capture(1000, response.authorization)
        render :text => 'Hazaa!'
      else
        raise StandardError, response.message
      end
    end

end

```

end

* * *

I also have this in my enviroment.rb

# Ensure the gateway is in test mode

ActiveMerchant::Billing::Base.gateway\_mode = :test

# Install the key

ActiveMerchant::Billing::PaypalGateway.pem\_file =  
File.read(File.join(RAILS\_ROOT, ‘config’, ‘paypal’, ‘test.pem’))

* * *

does anyone have any idea why this is happening? any help would be  
really appreciated.

It looks to me like you’re trying to test against the regular Paypal  
sandbox.

Paypal Pro is a completely different system, with a completely different  
test server!
