(C# UWP/WinRT) Firebase DELETE - Removing Data

Uses the DELETE method to delete data. The data used in this example is at Chilkat Firebase Pigs Database, and is shown here:

Chilkat Universal Windows Platform (UWP) / WinRT Downloads Chilkat for the Universal Windows Platform (UWP)

// Uses the DELETE method to delete a Firebase record.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// This example assumes a JWT authentication token, if required, has been previously obtained.
// See Get Firebase Access Token from JSON Service Account Private Key for sample code.

// Load the previously obtained Firebase access token into a string.

    return;
}

// Make the initial connection (without sending a request yet).
// Once connected, any number of requests may be sent.  It is not necessary to explicitly
// call Connect before each request.

// Chilkat's sample data (pig-rescue data) is publicly readable at: https://chilkat.firebaseio.com/.json
// This data is publicly readable, but not writable.  You'll need to 
// run against your own database..

// We're going to delete a pig we previously added.  The push ID of that pig was -KI3pT33wKauiMxY4QTB,
// so the path will be "/pig-rescue/animal/-KI3pT33wKauiMxY4QTB.json"

    // (The Chilkat REST API also has lower-level methods where an app can send the request in one call,
    // and then receive the response in another call.)
