bookmark_borderFastAPI Stripe Webhook Template

A FastAPI equivalent for verify-events-came-from-stripe.

import os

from http import HTTPStatus
from typing import Annotated

import stripe
from fastapi import Depends, FastAPI, Header, HTTPException, Request

app = FastAPI()

async def get_body(request: Request) -> bytes:
    return await request.body()"/webhook", status_code=HTTPStatus.NO_CONTENT)
def post_report(
    stripe_signature: Annotated[str, Header(alias="stripe-signature")],
    body: bytes = Depends(get_body),
) -> None:
    endpoint_secret = os.environ["ENDPOINT_SECRET"]

        # signature validation
        event = stripe.Webhook.construct_event(body, stripe_signature, endpoint_secret)
    except ValueError as e:
        # Invalid payload
        raise HTTPException(status_code=HTTPStatus.BAD_REQUEST) from e
    except stripe.error.SignatureVerificationError as e:
        # Invalid signature
        raise HTTPException(status_code=HTTPStatus.UNPROCESSABLE_ENTITY) from e



A possible catch, one that I ran into, is that I had FastAPI convert the request.body to a dictionary in the function parameters (so body: dict). Then I serialized it to a string for the validation step… and it failed because it was no longer identical to what came in.

bookmark_borderA chrome extension to navigate Github files differently

Last week, I was somewhat complaining that Github’s file navigator was not to my taste. When moving across files and directory, you have to go back and forth a lot. If you quickly want to switch between 2 files not in the same directory, it’s painful. Of course, one could open another tab, but tabbing doesn’t cut it. I wanted something more like a files navigator that we can find in any OS.

Then I though, hey, surely I can simply manipulate the HTML to make it work the way I want. I started coding… 45 minutes later, I had a working prototype of JavaScript code that I could simply paste in the browser console and bang; a nice file tree navigator-like experience right in Github.
