Paypal Express Checkout Error (10002)

[evilsorcerer1]

I got a bunch of errors when testing out zen cart checkout, and I don't see the downloads next to the products. Where can I find out what the errors mean? Actually, I'm not sure if they're all errors or some are messages. Here's some of it: termEC-8 termEC-3 Alert Paypal Express Checkout Error (10002) getLineItemDetails8 termEC-1
ec_step1 - 2 -submit and many more. Where do I find what these mean and how to fix them if necessary?

Although it may be "a very similar message" it isn't the same error message, and as such, will have a different cause and solution.

The OP's problem is difficult to answer due to a lack of relevant information. On the other hand, your error message is pretty darn specific.
The PayPal account authentication settings are not yet set up, or the API security information is incorrect

So, I have two questions for you.
1) Have the PayPal authentication settings been set up? and
2) Is the API security information correct?

The one you answer 'no' to, is the thing you need to do to get it to function. :)

Cheers

Just in case it might save someone else an hour if they are Googling this error.....

If you are copy-pasting the API signature code, it is easy to leave some old text behind when you double click on the existing one. Make sure the box is empty before you paste.

I'm getting the same error as RodG:

Please notify the store owner so they can correct this problem. (10002) 10002 Security error - Security header is not valid

IPN, API and SSL is all installed and configured. the two configure.php files have a "true" setting on SSL. I don't know what "Paypal account authentication settings are not yet set up" means. Does this refer to IPN or can someone tell me what this is?

Please don't post the same question in multiple threads. It often leads to confusion as to what is being done.

SOLUTION!!

Review your API information for a sixth time. As said elsewhere in this forum, you can add an extra space or delete a character. and when you come back to view your payment module, things can alter. In my case, the API signature-username appeared twice, so when I did one of my redos, although I had a blank text field, the former username was there but not visible. It was only when I left the payment module and returned back to it later for another try that the double username appeared.

When I called PayPal web services tech support (they are very helpful), they said the "Error 10002 Security header is not valid" is always an API information issue. Something has been incorrectly typed.

dbltoe helped me by saying to check with the web host that the ports are all correctly open since Paypal seemed not to be able to connect to our store. Ports were good, so next step was to call PayPal and ask them if there was a problem from their end to connect to our store. PayPal support person immediately checked the store and got the same warning box mentioned above. This led PayPal tech support to say that there was an API information issue. And the rest is history!

I fixed it by reinstalling my "API Signature -- Signature Code" again and again and... It did not want to take my paste, triple check it.
