Fedex Plugin problem

-- url of the page with the problem -- : lotusthreads.com/index.php
-- HikaShop version -- : 1402191935 (starter 2.3.0)
-- Joomla version -- : 2.5.19
-- PHP version -- : 5.3.5
-- Browser(s) name and version -- : All
-- Error-message(debug-mod must be tuned on) -- : No shipping method found (unregistered users) - Fedex authentication failed no shipping method found (resgistered users)

Hi, I'm having this error, I'm using the test credentials of Fedex. I already read all the documentation and FAQ, and I did not get the solution. Here is a screenshot of the config:

Also, a client is concerned about the security of Hikashop and joomla, someone told him that is possible for some people to enter the backend and change the prices in order to buy the products for a minor price. Is that possible? How can I improve the security for prevent issues like that?

Edit:

I called Fedex tonight and the guy told me that I have to change the URL from production to TEST. But there is no option in the plugin to do that. How can I change that url?

Hi. The test url is as follows:

Test URL: wsbeta.fedex.com:443/web-services

Ok we were able to pass the autentication issue, but the different options for the shipping (e.g. ground, express, etc.), how we can fix this?

Ok, we solve all the issues, thanks for helping us.

Hi. We were able to make the shipping request with the fedex plugin, but now we want to go further an add the capability to create the email labels for printing. We have download the codes from the Fedex website, but we were unable to integrate them with the plugin. Could you give us any help with this?

Hello,
Can you give me more information ? how and when do you want their "printing label" code to be applied ?

Hi, what we need is that at the end of the transaction, the code send a png label via email. Here are teh codes provided by Fedex, but we just dont know how to integrate them to the wdsl and php files of the plugin.

The solution will probably be to apply your code at the end of the OnShippingDisplay function, regarding the rates that will be added on the "$usable_rates" variable.

Hi:

For the future if you want to run in test mode edit the fedex_rate.wsdl file, change this line:
<s1:address location=" gateway.fedex.com/web-services/"/ >
to this:
<s1:address location=" wsbeta.fedex.com/web-services/"/ >

REMEMBER to change it back when you launch this in production.

Best,
Jay
