no data returned posting to API

I have a Wordpress plugin that posts to a custom shipping API in Australia.

Now recently the API has been updated to .Net MVC and the plugin code no longer works, even though I have updated the URL used etc. Could the params be the issue due to the fact that they're using MVC and the actual url structure has changed?

Website: http://www.portdouglasgiftbaskets.com.au/ - just add a product and view the basket

Here's a working URL on the API:

http://farmapi.fastway.org/v2/psc/lookup/AUK/Elsthorpe/4110/5?api_key=YOUR_API_KEY


I would love it if someone could tell me what is wrong as I am not a PHP developer.

It's a little hard to research this because the plug-in appears to be very thinly used (Example: Google cannot find it at WordPress, and CNET has a lifetime download count of 139 and zero reviews).  But that said, it looks like it's a paid product, and the current version may be 1.5+?  According to the code snippet you've got version 1.0 so that may argue for an upgraded version of the plug-in.

Usually when a publisher has an API, the best practices call for a Versioned API, in other words, the publisher will not make a change to the inputs and outputs for any given version and will only make changes like that to a new version of the API.  So if your existing code suddenly broke, you have a support issue with the API vendor.

There is only one cURL call in the scripts and that is devoid of any error visualization.  I would be reluctant to try to talk you through how to get error displays if you're not at least a medium-advanced PHP programmer (too easy to break something), so my first recommendation is contact both the plugin vendor and Fastway.

Sidebar note: Fastway says they have an API, but there seem to be no links to it (?).
