Google Cloud function to fetch data from third party server

Question

I am new to Google Cloud Functions features and implementation. So I want to know that is it possible to make HTTP or HTTPS request to third party server API using Cloud function and if yes then how? And when I receive data in response can I store it into my firebase database using same cloud function instance?

And how can I make this request to be called periodically or schedule it? Thanks in advance

Here's how to do it using node-fetch.

Your Cloud Function:

const fetch = require('node-fetch');

exports.functionName= (req, res) => {
  const fetchFromURL = async () => await (await fetch('https://yourURL.com')).json();

  fetchFromURL().then((data) => {
    // do something with data (received from URL).
  });
};

You will need to add the "node-fetch" dependency to your function's package.json as well.

Your package.json:

{
  "name": "sample-http",
  "version": "0.0.1",
  "dependencies": {
    "node-fetch": "^2.6.1"
  }
}
