Your app needs to know the moment a payment succeeds. So how often should it ask? Or what if it never had to ask at all?
This is the webhook pattern explained end to end with one example carried all the way through — an online store waiting on a payment. You'll see why polling burns requests to discover nothing and still finds out late, how a webhook flips the direction so the provider calls you, and what actually happens on delivery: the event fires, the provider sends an HTTP POST, your app verifies it came from the provider, and you answer 2xx.
It finishes on a real Ruby on Rails endpoint and the three things that decide whether the integration survives production: verify the signature, handle duplicate deliveries idempotently, and push the slow work into a background job before you respond.
One thing this video is deliberate about: webhooks are not a free upgrade. Delivery can be delayed, duplicated or dropped depending on the provider and the network. A 2xx means received, not handled perfectly. And reconciliation polling still has a job to do. Neither pattern wins everywhere — they are different trade-offs.
