How WebHook works | System Design

UPDATE:
In the example provided in the video, the client app was mistakenly making periodic requests to the server (every five seconds) to check for updates. This approach is not the correct way to use webhooks, as it defeats the purpose of real-time updates without polling.

In a proper webhook implementation, the client app would provide its webhook URL to the server, and the server would push updates to the client as soon as they become available. The client app should not actively check the server at regular intervals. Pinned the comment with updated code, can't post the updated code in description.

I thought the whole idea is for the client not having to call a server, in the example the client app is calling the server every five seconds?!

[Abhi-tpdk]

The video has confused me regarding why polling is being used at regular intervals. From what I understand, a webhook is when a client (i.e., server) provides an HTTP URL, which will be used by another server. Any event with data change will trigger this HTTP request with data change, and correspondingly, the client server will respond.

Push notifications are specifically designed for sending notifications to mobile apps on users' devices.
Webhooks are not designed for direct communication with mobile apps on users' devices but rather for server-to-server communication or data synchronization between systems.
The flow might look like this: Event occurs → Webhook is triggered → Your server processes the webhook and sends a push notification to the user's mobile app.

Thank you for this very clear explanation. I am product managing a team that is using webhooks. This helps me write stories / follow the planned tech work.

First video that enabled me understand the concept of webhooks. Great content

[mrbinary]

This is the best explanation I have found so far on how webhooks work. Excellent video. Thank you.

[vishalbindal]

thanks for this finally i am able to understand the concept of webhook

[varunafernando]

Great explanation. I watched 10 videos on this topic and your explanation was the best. Thank you

[pickkideb]

This channel is a hidden gem. Continue to put your effort bro, your channel will grow for sure. By the way, this is a great explanation of WebHooks.

[hedgewizardly]

Thank you! I've watched several of these videos and somehow not a single one of them got to the point or explained it well enough, but this got me up to speed in about 1:35s. Thank you!

[mrigankadhar]

You know after exploring a lot of videos this one video wiped all of my doubts regarding webhooks!! A great video maan!!

[ambikeya_tech]

Insightful breakdown! Your clarity on WebHooks in system design is invaluable. Appreciate the educational content, looking forward to more!

[skoushicksuri]

Excellent explanation of webhook concept and it's comparison with websockets. Thanks for this video. 👍

[Ravi]

Clear and to the point explanation, thank you so much! Very clear voice too.

[prashantbismani]

Great explanation, please keep posting such informative videos

[IYI_WOLF_IYI]

This is such a good explanation, well done!!

[aghahowajeffrey]

Thank you for this beautiful explanation

[OrionValencia]

Thank you! I think that I understand this but I just want to confirm my logic on this. In my case, I want Stripe to send a notification whenever an order is placed. Can I used Wix as an endpoint to receive that notification? Do I need to download a 3rd party app for set this up or can I simply use Stripe CLI and Dev. mode on wix?

In client web hook you explained, it look like long polling mechanism.

Can you exlplain how to work server according to your example client code? Thank you!

Let's say I have used a third party Chat API. When a new message is received to the chat API, it will call the web hook endpoint (with POST method) of the back-end I've developed. This request includes the 'message, sender, recipient'. Now the back-end and frontend app has a websocket connection. So the backend is able to do further processings for the received message and also meanwhile it can send the message to relevant recipient via websocket. I think this is a real world scenario of web-hook.
