Follow this guide to fetch 🇦🇹 Austria Postal Codes data from your Kotlin app. The HttpURLConnection library will be used to fetch the database data through its REST API.
First you need to connect your app to the 🇦🇹 Austria Postal Codes database. It will authorize you to access this database API using your app keys. If your app doesn't have keys at Back4App yet, they will be generated during this process.
If your app is already connected to this database, you don't need to do this process again. Just select your app from the list below.
For your convenience, you can also use a fake app (test purposes only) and leave this step to be done later.
Now let's customize your query to fetch the data that you need!

After running the app, you should see the following output in your app logs:
