How To Do a Simple URL Based Service

How To Do a Simple URL Based Service

I want to do a very simple service, but cannot figure out how.
I want to launch a URL like http://myapp/Entry1.aspx?zip=90210
I want my OutSystems app to recieve the zip code value 90210 that was specified in the query string.
I then want OutSystems to then query a local Entity to retrieve the state code (CA in this case).
And last simply return the value CA to the browser.

How can I do this simple task?

Hello Jeff.

You can add an input parameter to your webscreen named zip and then in your preparation screen use it in a query.
After that you can use the query output to do whatever you want.

I've attached a screenshot.
