node.js - Parameters in Firebase Cloud Functions HTTPS

Question

How can I set some parameters on my HTTPS functions in Firebase? I am building an app, and while building the app, I have managed to grow my mailing list. Now I want to send mails out, but I want to make sure that they can unsubscribe before I send anything out.

I am using Firebase for everything, and I have managed to make a function that sends mails out to every subscribed mail.

I am also able to "unsubscribe" a specific mail, but that is hardcoded, and not at all an optimal solution.

exports.testUnsub = functions.https.onRequest((req, res) => {
  var db = admin.database();
  var ref = db.ref("mailingList/-KhBOisltrOmv57Mrzus");
  ref.child("subscribed").set(false);
  console.log("-KhBOisltrOmv57Mrzus has unsubscribed from mailing list.");
});

In the mail I send there is an URL, which triggers this HTTPS function. I want to set a parameter on that URL so it becomes dynamic. Something like:

https://us-central1-<project-id>.cloudfunctions.net/testUnsub?listID=xxxxxxxxxxx

I am looking for anything that can get me on the right direction.
