In this episode, we dive into handling successful payment intents from Stripe using webhooks. Now that our webhooks are being delivered, we set ourselves up to not just handle the current event (like payment_intent.succeeded
), but also to be able to handle more events in the future without much refactoring.
We start by grabbing the payload from the webhook request and breaking down how to extract the event type. Then, we set up a system in our webhook controller to automatically route each event type to its own method - for example, handlePaymentIntentSucceeded
for a payment_intent.succeeded
event. We use some handy string manipulation to transform the event type into the appropriate method name, and then call that method dynamically if it exists.
Throughout the episode, we add checks and log output to make sure everything is working as expected. Once we trigger another payment, we check our logs and see that the correct method is getting called and the full payload is available, including the user ID—setting us up perfectly for the next episode where we'll use this data to actually upgrade a user after they've paid.
So, we've just built a neat event handling system that makes it super easy to expand as we need to listen to more Stripe webhook events. Next up: taking action when a payment is successful!
