Building a Webhooks System

Do you need to integrate with external systems or services? Leveraging an event driven architecture enables you to build a webhooks system that can be decoupled from your main application code. Enabling you to call external systems that have subscribed via webhooks in complete isolation from your application code.

New to system design, great to learn.

Azure durable functions can cover these scenario’s and one of the best fit’s

Very timely! I am currently writing a webhook processor for a major hotel company.

What i did in my app is that i create a simple mechanism to create a new task from main thread which will execute a handler within the same application but will have its own lifetime and everything, hence no need to await from main thread, since i dont want to add a rabbitmq instance for now and keep a simple monotholic approach. In case i have a lot of users, adding another node of the same app increases the processing power as well. If that will not work out then i can switch to rabbitmq easily because the handling logic is encapsulated properly

As an alternative to sending it back to RMQ, you could have a (simple) internal Event Bus.Your web hook would still have the Subscriber to get the message from RMQ, your function would then send an event signal to all the external subscribers via whatever mechanism is defined for each subscriber. Probably a splitting of hairs here but I tend to lean towards keeping my Brokers self contained and not back feeding the source in a round robin manner.

Having a well designed topic structure allows you to skip the middle layer Webhook. The fine grained, backend system specific Webhooks would subscribe to the topic (and maybe partial data pattern) they are capable of dealing with.

But what about the replies? Does this approach assume fire and forget semantics? And what about acknowledging? How will the Application find out that this particular hook is processed? Is there any standard way of doing this? So far those are just fancy words on top of what have been around for decades...

Great video. I might need to use it soon...😅

Technically speaking, if you separate the webhook from the other processes, is it still a web "hook"? I've been told the name and definition comes from the fact that it "hooks *into*" some other process. If you separate it, it is no longer hooking into anything. Right?

I am so confused bro. Am a self taught developer. i need direct assistance integrating webhook events with my flutterflow app which should send alerts when a payment is made through the payment gateway i used: YOCO

[ahmadjaber]

Is using both return value from stripe and updating my backend + using webhooks as a redundant a good solution?

[jdang]

Can we remove the WebHook project, and on the external projects, subscribe to the channels the system needs? What do we gain when using the Webhook over Pubsub?

[thatoneuser]

Would you consider the cross-language ReactiveX API an implementation of pub-sub, or do you think that's just an observer?

[shaunwhyte]

How would Auth be set up to external clients?

[mhDuke]

why do we need the extra webhook service layer?! it seems redundant!
