FreshBooks API Libraries

I am new to FreshBooks (not only the API) and I want to use it for some automatically generated invoices. I was trying to run some of the source code examples (the PHP and JS libraries in particular): http://developers.freshbooks.com/api/samplecode/

The problem is that I get an error message: "Connection error"

Do I need to set up anything else in the example files besides my API a开发者_如何学Gond token obtained from the FreshBooks site?

I am running the examples from a local server but I don't believe that's the problem.

I'm going to post Mr. Sewani's answer here, because I believe it can be useful to other people as well:

Sorry that you are having trouble with that library. I just tried myself and I get the same error from the Javascript+PHP library. I have checked that the servers are working properly, so I am quite convinced it is a bug in the library. Sorry that we led you astray there. I'll take a closer look and re-evaluate which libraries we list in the docs.

If you are comfortable switching languages, I would particularly recommend the Python or Ruby ones I mentioned before, as we have a number of people using those successfully.

Hopefully, the PHP and/or JS libraries will be fixed soon so the API can be used with these programming languages.
