Using Website Information Without WebView

I am very new to this, and I more looking for what information I need to study to be able to accomplish this.

What I want to do is use my GUI I have built for my app, but pull the information from a website.

If I have a website that looks like this:

(full website can be seen at

What would I need from the website so that if a user entered an error code here:

It would use the search from the website, and populate the error description in my app?

I know this is a huge question, I’m just looking for what is actually needed to accomplish this, and then I can start researching from there. — Or is it even possible?


What you’re going to need is some kind of a web services api on the server you want to search. Then you can post http requests to send and receive information from the server.
