You're about to initialize a Firebase project in this directory:

 /your_folders/your-project-name


=== Project Setup

First, let's associate this project directory with a Firebase project.
You can create multiple project aliases by running firebase use --add,
but for now, we'll just set up a default project.

? Please select an option: (Use arrow keys)
❯ Use an existing project
 Create a new project
 Add Firebase to an existing Google Cloud Platform project
 Don't set up a default project

const functions = require("firebase-functions/v1");

const admin = require("firebase-admin");

const serviceAccount = require("./serviceAccountKey.json");

// Initialize Firebase app for database access
admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: "https://name_of_the_database.europe-west1.firebasedatabase.app",
});

// This function will serve as the webhook for incoming SMS messages,
// and will log the message into the Firebase Realtime Database
exports.inboundSMS = functions.https.onRequest(async (req, res) => {
  let params;
  if (Object.keys(req.query).length === 0) {
    params = req.body;
  } else {
    params = req.query;
  }
  await admin.database().ref('/msgq').push(params);
  res.sendStatus(200);
});
