Firebase POST - Pushing Data

See more Firebase Examples

Uses the POST method to append a new record at a particular location in the database. Firebase automatically generates the push ID and returns it in the response. The data used in this example is at Chilkat Firebase Pigs Database, and is shown here:

// Push a new record to a Firebase JSON database using the POST HTTP method.

// 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.
