🧭 How to Exclude a Route from Global Prefix & Versioning in NestJS

In NestJS apps, it's common to use global route prefixes and versioning like /api/v1. But sometimes you need a public-facing endpoint — such as a payment gateway callback — that must live outside those constraints.

Here’s how to expose routes like /payment/callback without the global /api/v1 prefix.

🔧 Problem
You're using global prefixing and versioning like this:

main.ts:

app.setGlobalPrefix('api'); app.enableVersioning({ type: VersioningType.URI, defaultVersion: '1', }); 

✅ Resulting in routes like:

/api/v1/auth/login

/api/v1/user/profile

❌ But now you need /payment/callback to be exposed at:

http://localhost:3000/payment/callback

Instead of:

http://localhost:3000/api/v1/payment/callback

✅ Solution Overview
You need to do two things:

⛔ Exclude the route from the global prefix

⛔ Mark the route as version-neutral

1. Exclude the Route from Global Prefix Update main.ts:

import { RequestMethod } from '@nestjs/common'; app.setGlobalPrefix('api', { exclude: [{ path: 'payment/callback', method: RequestMethod.GET }], }); 

This tells NestJS to ignore prefixing for GET /payment/callback

🚫 No leading slash in path (correct: payment/callback)

1. Mark Route as Version-Neutral Update your controller:

import { Controller, Get, Version, VERSION_NEUTRAL } from '@nestjs/common'; @Controller('payment') export class PaymentController { @Get('callback') @Version(VERSION_NEUTRAL) callback() { return 'Payment callback hit!'; } } 

✅ VERSION_NEUTRAL tells NestJS: “do not apply any version prefix”

🧪 Final Result
http://localhost:3000/payment/callback ✅

http://localhost:3000/api/v1/payment/callback ❌

All other routes still work normally under /api/v1.

🧵 Conclusion
NestJS makes it easy to maintain clean API versioning — but when you need an exception like a public payment callback, it only takes

two steps:

• Exclude the path in setGlobalPrefix()
• Add @version(VERSION_NEUTRAL) to the controller
