# Uses the PATCH method to update 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.

# 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..

    # and then receive the response in another call.)
