When a child is updated or created in firebase database, I need to trigger a REST API. How to go about it?
Tried using "stream" function, but in order to invoke stream everysec will have to create a cron job. I would like some trigger to be done through firebase to call API.

I'm sorry but this question is a mess. What it has to do with Django ? What did you tried so far ? Could you please, share some code.

You say you "Tried using 'stream' function", which I assume means streaming data from the REST API. That API should not require a CRON job to constantly poll, but it will require a process that keeps its connection open. If you want us to help with that implementation, update your question to show what you tried.

Sorry for the confusion, i used "pyrebase" package to stream changes. Anyway i went ahead with cloud functions to resolve the issue. Thanks

If you are using the Firebase Realtime database you can use Cloud Functions that trigger on a write to your database. Here is some docs that explain it a bit more. An example from the docs is below. Basically on a create to the database at /messages/{pushId}/original it will trigger this code that you could process your logic in or call your rest api. You can also do this with Firestore as well.
exports.makeUppercase = functions.database.ref('/messages/{pushId}/original')
.onCreate((snapshot, context) => {
// Grab the current value of what was written to the Realtime Database.
const original = snapshot.val();
console.log('Uppercasing', context.params.pushId, original);
const uppercase = original.toUpperCase();
// You must return a Promise when performing asynchronous tasks inside a Functions such as
// writing to the Firebase Realtime Database.
// Setting an "uppercase" sibling in the Realtime Database returns a Promise.
return snapshot.ref.parent.child('uppercase').set(uppercase);
});

I think onWrite would be better since the requirement is for both create and update

CorrectonWritewould better suit this instance if its the same endpoint, but if they are different rest APIs for create and update. you'd wantonUpdateandonCreate.

https://firebase.google.com/docs/reference/js/firebase.database.Reference#on
const ref = firebase.database().ref("node/you/want/to/observe");
ref.on('value', function(dataSnapshot) { //here you do your API call });
BTW - you don't have to 'invoke stream every sec'. You create on listener that will trigger whenever condition is met. Juts remember to turn it off when you're done.
