The process involves configuring TCP communication between microservices, updating database status using MongoDB operators, and utilizing event patterns for asynchronous state transitions.

0:00 Finish this webhook implementation off. 0:02 The first thing I wanna do is head back into the reservation service, 0:07 specifically into the reservations controller. 0:10 And in here, we want to now add a couple of event 0:13 patterns that 0:14 we can listen for events from the payment service. 0:17 Now, I think this is also a really cool example 0:20 because it can show you that 0:21 you can actually mix together HTTP controller 0:25 methods with 0:26 microservice TCP or any other controller methods. 0:30 So here we can simply add a new event 0:34 pattern decorator and listen for the paymentSucceeded 0:37 event, which remember we set up earlier in our 0:40 common DTO. 0:42 We'll set up our usePipe for ValidationPipe to make sure we have 0:46 validation, 0:48 and set up async 0:49 handlePaymentSucceeded. 0:54 And we'll destructure or extract the incoming TCP 0:58 payload, which will be of type PaymentSucceededDTO. 1:03 And now we'll call this 1:05 .reservationService.handlePaymentSucceeded 1:10 and pass through that payload, which of course we'll have to set up, 1:14 which 1:14 we'll do shortly. 1:16 Let's go ahead and do the same thing for payment failed event. 1:21 So I'll add paymentFailed, 1:23 use pipe, new ValidationPipe. 1:27 And now this will be async handlePaymentFailed. 1:31 Pass through that payload 1:34 of type PaymentFailedDTO, 1:38 and we'll return this 1:39 reservationService.handlePaymentFailed 1:44 with the payload. And so now let's add these inside of the 1:47 reservation service. So this is gonna be pretty straightforward now 1:51 in the reservation service. Let's go ahead and start off with 1:55 async handlePaymentSucceeded. 2:01 We'll go ahead and destructure the reservationId as well as the 2:05 paymentIntentId 2:09 from 2:10 the PaymentSucceededDTO. 2:14 And firstly, we can go ahead and add a log 2:18 statement just to make it more clear that we've actually received this event. 2:22 So let's go ahead and create 2:25 our private readonly logger 2:28 of type new Logger from Nest common, 2:32 pass through our 2:32 reservationService.name. 2:39 And now we can use this to log something out.
