PayPal account authentication settings are not yet set up

**dustbowl** · 1 Oct 2011, 09:23 PM

I have installed paypal express on zen cart 1.3.9.

When I click on the paypal button, I get this error message.

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) 10002 Security error - Security header is not valid

I have read the help me files but have not anything on authentication settings.

I have tripled checked the API settings(user name, password, api password, signature, etc..) and they are correct.

I'm not sure what the authentication settings are?

Ok, I figured it out.
I had to unistall the paypal module and reinstall it with the correct API settings.
Thanks

I am having the same problem but do not really understand how did you solve the problem.

I enter the correct user name, password, and signature. Could you provide more detail of your solution?

You must enter the correct API details, exactly as PayPal gives them to you.
And, use the Live site. Don't bother with sandbox.
Instructions here: www.zen-cart.com/getpaypal

If you're 1000% certain you've done that exactly, the report back with the EXACT error message YOU are getting.
