Hello I have my Paypal signature , password and username API integrated with sandbox and set up on 2 websites and they work fine at checkout for either "test" or "actual" payment. However i have tried to use the same Signature , Password and API to integrate with a google android app that i have created through a 3rd party app platform. There is a section in the "stores" tab that you can fill in the signature , password API as per my websites. The problem is on checkout when i click the method of payment" as paypal it pops up with the following message "Web Page not found" ??? Do I need to request a new API-Siganture , password from paypal for this app ? Can anyone help resolve this ?
