## TL;DR

2. - request.get\_data() returns the raw bytes; pass them straight through. - Do not call request.get\_json() first, even for logging.

```text
from flask import Flask, request, abort
import stripe
import os

app = Flask(__name__)
SIGNING_VALUE = os.environ['STRIPE_WEBHOOK_SIGNING_VALUE']

@app.route('/webhooks/stripe', methods=['POST'])
def stripe_webhook():
    payload = request.get_data()
    sig = request.headers.get('Stripe-Signature')
    try:
        event = stripe.Webhook.construct_event(payload, sig, SIGNING_VALUE)
    except (ValueError, stripe.error.SignatureVerificationError):
        abort(400, 'bad signature')
    # switch on event['type'] ...
    return {'received': True}, 200
```

## When to use

You are seeing this: Flask does not parse the body unless you ask, which makes this the simplest framework on the list. Use this skill when you run into "Stripe webhooks on Flask: verify against request.get_data(), not request.json".

## 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.

## Steps

1. Flask does not parse the body unless you ask, which makes this the simplest framework on the list. The trap is habit: calling `request.json` or `request.get_json()` anywhere before verification. Use `request.get_data()`.

2. - `request.get_data()` returns the raw bytes; pass them straight through.
- Do not call `request.get_json()` first, even for logging. Once parsed, the byte match is gone.
- Behind a proxy, make sure the proxy forwards the body untouched (no compression transforms on the webhook path).
