BryceJr Posted December 20, 2011 Share Posted December 20, 2011 (edited) You are porbably using "LIVE" keys and cerificates on a "SANDBOX" or test mode. Paypal sandbox behaves like a live transaction server except it uses fake accounts. Transactions are contained within the "sandbox". Once everything is set up correctly and working fine, then, you can switch it to LIVE. Did you set up a sandbox account? Also, read the "Sandbox" user guide. You can sign up for a sandbox account at https://developer.paypal.com Sandbox user guide >> https://developer.paypal.com/en_US/pdf/PP_S...x_UserGuide.pdf Edited December 20, 2011 by BryceJr Quote Link to comment Share on other sites More sharing options...
