API wrappers are language-specific files that you can include in your projects to make working with the Wufoo API easier. These are by no means required and you could write your own code that does what they do or not use a wrapper at all, but chances are a wrapper is going to make your life easier.
API wrappers provide functions you can call (and provide parameters to) which return the data from the Wufoo API back to you in some kind of useful format.
“Official” in the sense that we developed these in-house at Wufoo.
These have been created (and open sourced) by Wufoo users who created them for their own projects.
All of these wrappers are hosted available on our GitHub account in pubic repositories. That means you are free to download them, use them, and even fork them and make your own changes. If you make a change you feel everyone can benefit from, feel free to issue us a pull request from your forked repository and we’ll take a look and pull it into the main branch.
