Shiker Posted May 10, 2012 Share Posted May 10, 2012 I had this problem since a while. Normally Error 1002 is in relation with bad API credentials, but for me it was other thing, not credentials configuration. Check here and try this. Link to comment Share on other sites More sharing options...
Never_give_up Posted July 25, 2013 Share Posted July 25, 2013 (edited) incase anyone has the below error.... Paypal was working fine then stopped for no reason. I haven't done anything to my shop. error is as follows at the end of checkout: Authorisation to Paypal failed Please refer to logs: 01. Paypal response: 02.-> 03. Paypal returned error I called up Paypal and they said: it could be 1of 2 things... 1st if your hosting service uses a 3rd party service called Rack Space - they may be blocking Paypal ip because they were having problems with hacks. 2nd if your hosting service uses a server or service called ATT... it could be the reason why... some kind of conflict or bug or blockage. It's a hosting service problem.... put in a support ticket to your hosting service to fix. EDIT: it turned out to be ATT fault and my hosting tech support fixed it. Make sure you give your hosting service tech support the above information so they know where to start looking for the problem.
