PayPal standard API

Hi

I am using "HikaShop Paypal payment plugin". I have given the sandbox E-mail id and sandbox URL
But i am getting the message "Please login to use the Paypal Sandbox features" (Please see the attached screen shot of the paypal message)
Where i have to enter the API username and password , etc...?

Thanks

Hi,

I think that you'll probably find your answer there :

You should already be logged in to the sandbox BEFORE testing your transactions and that way you will directly see the normal paypal interface after the checkout.

Hope this will help you.
