Did anyone work with SunLight foundation data to map the zipcodes with legislative district data. I have to work with Illinois zipcodes only.

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
If you are attempting to match zip codes to legislative districts, the Sunlight Foundation API is not the way to go, as far as I can tell. You would have to query the API for each zip code in turn to get the district. If you have a list of the zipcodes and can write code to query the API (there are implementations in Python and the other usual suspects), you could do this.
If all you're looking for is a table of correspondence between Congressional district and zip code, you can download that directly from the Census website
I work at Sunlight. I'm not sure why Llaves thinks our APIs aren't a good choice for this versus, say, a PDF that's going to need to be parsed (and which assumes, incorrectly, that a ZCTA and Zip Code are the same thing). In fact our API is designed to support exactly this use case, and has a number of client libraries available to simplify the process.
A few suggested links. Unfortunately, it looks like this site is limiting the number of links I can include, so I'll have to ask you to head to this pastebin link and grab the URLs from there.
I hope this is helpful! If any additional questions come up, I'd encourage you to ask them on the Sunlight Labs google group.
