Paypal Module - Authentication Error

[DGPublishing]

Greetings Friends,

 

I know this error has been covered in the past and also resolved, however those resolutions are not working for me.

 

I'm having a problem with the PayPal module. I am currently trying to test in Sandbox mode so I don't have to undo a bunch of transactions. I have recieved my API Key, API Password, and Signature and put them in to the module. When I try to complete at transaction this is the (verbose) error that I recieve:

 

Please refer to logs:

1. Making new connection to 'api-3t.sandbox.paypal.com/nvp'
   
2. Connect with CURL method successful
   
3. Sending this params:
   
4.

5. Send with CURL method successful
   
6. PayPal response:
   
7. TIMESTAMP -> 2011-11-13T05:33:46Z
   
8. CORRELATIONID -> 5de00afc3e6df
   
9. ACK -> Failure
   
10. VERSION -> 60.0
    
11. BUILD -> 2256005
    
12. L_ERRORCODE0 -> 10002
    
13. L_SHORTMESSAGE0 -> Security error
    
14. L_LONGMESSAGE0 -> Security header is not valid
    
15. L_SEVERITYCODE0 -> Error
    
16. PayPal returned error
    

Now here are some troubleshooting steps that I have taken.

 

1) I have revoked the API Username and Password, and issued a new one, entered that information in the module and ... error

2) I have uninstalled the PayPal module (which was 2.8.3) and deleted all copies from the module folder, and replaced it with 2.8.4. I then reconfigured the module with the new settings .... error

 

So I know it's an authentication error, but why? I'm not sure what else I can do. Can anyone give me a hand?

 

Cheers,

Update

Ok so after some more searching I found the sandbox sample API but I am still getting the same error

I'm pretty sure you have to use a Paypal sandbox account to get the module sandbox to work. Paypal will generate all the same authentication routines and feedback to prestashop without a real transaction taking place.

 

Have a look in Help on the Paypal website.
