## TL;DR

`` // src/routes/webhooks/stripe/+server.ts import Stripe from 'stripe'; import { STRIPE\_API\_KEY\_VALUE, STRIPE\_WEBHOOK\_SIGNING\_VALUE } from '$env/static/private'; const stripe = new Stripe(STRIPE\_API\_KEY\_VALUE); export async function POST({ request }) { const rawBody = await request.text(); const sig = request.headers.get('stripe-signature'); let event; try { event = stripe.webhooks.constructEvent(rawBody, sig, STRIPE\_WEBHOOK\_SIGNING\_VALUE); } catch (err) { return new Response('bad signature', { status: 400 }); } // switch on event.type... return new Response(JSON.stringify({ recei

## Steps

1. SvelteKit `+server.ts` handlers receive a standard Web Request, like Next.js App Router. Read it with `request.text()` and never call `request.json()` first.

```
// src/routes/webhooks/stripe/+server.ts
import Stripe from 'stripe';
import { STRIPE_API_KEY_VALUE, STRIPE_WEBHOOK_SIGNING_VALUE } from '$env/static/private';

const stripe = new Stripe(STRIPE_API_KEY_VALUE);

export async function POST({ request }) {
 const rawBody = await request.text();
 const sig = request.headers.get('stripe-signature');
 let event;
 try {
 event = stripe.webhooks.constructEvent(rawBody, sig, STRIPE_WEBHOOK_SIGNING_VALUE);
 } catch (err) {
 return new Response('bad signature', { status: 400 });
 }
 // switch on event.type ...
 return new Response(JSON.stringify({ received: true }), { status: 200 });
}
```

2. - `$env/static/private` keeps the values out of client bundles; never import them into `+page.svelte` files.
- SvelteKit does not parse the body for you, so the only trap is calling `.json()` out of habit.

## When to use

You are seeing this: SvelteKit +server.ts handlers receive a standard Web Request, like Next.js App Router. Use this skill when you run into "Stripe webhooks on SvelteKit: request.text() in +server.ts before anything parses".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
