help with 503 error code

Hello! I have a nest.js and postgres app on Railway We integrated stripe to manage the payments. Every time a user buys a ticket is redirected to a stripe payment gateway (out of the website domain) On the backend we have a webhook listening for the stripe payment process to complete. We have a webhook endpoint listening but it appears the request doesn't go through while running on Railway (works fine on local though) Question: How to get the webhook request my railway app to go through

You can use the railway provided variable RAILWAY_STATIC_URL in code to register your webhook endpoint.

⚠️ experimental feature

where do you register this webhook?

VRBallerOP•2y ago

It's an endpoint in our app. /payments/webhook

Brody•2y ago

yes but where do you tell stripe to call that endpoint?

VRBallerOP•2y ago

Ah, Stripe has https://dashboard.stripe.com/test/webhooks. It's registered there

Brody•2y ago

screenshot please

okay looks fine now show me the bit of code that handles that endpoint

VRBallerOP•2y ago

@Controller('payments')
export class StripeController {
  private readonly logger = new Logger(StripeController.name);

  constructor(
    private readonly prisma: PrismaService,
    private configService: ConfigService,
    private stripeService: StripeService,
  ) {}

  @Post('webhook')
  async handleStripeWebhook(
    @Req() req: RawBodyRequest<Request>,
    @Res() res: Response,
  ) {
    console.log('webhook-stripe-controller');

@Controller('payments')
export class StripeController {
  private readonly logger = new Logger(StripeController.name);

  constructor(
    private readonly prisma: PrismaService,
    private configService: ConfigService,
    private stripeService: StripeService,
  ) {}

  @Post('webhook')
  async handleStripeWebhook(
    @Req() req: RawBodyRequest<Request>,
    @Res() res: Response,
  ) {
    console.log('webhook-stripe-controller');

Brody•2y ago

what language is that

VRBallerOP•2y ago

Typescript

Brody•2y ago

looks gross

VRBallerOP•2y ago

... That makes you look bad ngl Actually works quite well look up nest.js

Brody•2y ago

im not saying your code is gross anyway

VRBallerOP•2y ago

Haha it's fine I appreciate you helping!

Brody•2y ago

can you send a post request to that endpoint (while running on railway) with something like postman?
