Hi,

I have followed Cody F.'s tutorial ‘PayPal Express Payments with  
ActiveMerchant’  
[[http://www.codyfauser.com/2008/1/17/paypal-express-payments-with-activemerchant](http://www.codyfauser.com/2008/1/17/paypal-express-payments-with-activemerchant)]  
and its working fine for me in my local system. But when I try to move  
the code in my server, the code is not working.I get the following  
error:  
"This transaction is invalid. Please return to the recipient’s website  
to complete your transaction using their regular checkout flow. "

NB: I was logged into the [developer.paypal.com](http://developer.paypal.com) when trying to do the  
checkout. Can anyone throw some light into this ?

-Saurav

I also want to add that without even login to the [paypal.developer.com](http://paypal.developer.com),  
I get the same error.

I think something is wrong with paypals test environment… I  
commented out

#config.after\_initialize do

# ActiveMerchant::Billing::Base.mode = :test

#end

in config/environments/development.rb and it seems to work fine now.  
Well, its asking me to log into paypal at least, I try to login but my  
login matches my merchant login, so it complains about that. But  
still, I think its working fine.

Could you solve the problem ?

I have implemented it with Ruby PayPal SDK. Its working fine for me now.
