Hi all
I am a newbie.
I have a problem that I am sure you clever lot can help me with.
I have a business paypal account, and I am trying to get pay pal express to work.
It seems I have to register first a API account.
I have done this at the paypal end it says the the IPN has been activated.
But when I can use the shopping cart right to thepoint of having to register and then I get.
We are sorry for the inconvenience. The PayPal account authentication settings are not yet set up, or the API security information is incorrect. We are unable to complete your transaction. Please notify the store owner so they can correct this problem. (10002)

Now what I done in the admin is IPN url http//my website name.co.uk/ipn_main_handler.php
The return is
http// mywebsite name.co.uk/index.php?main_page=checkout_process

Can someone HELP PLEASE I would be very grateful.

Warm Regards
Cliff
