Sign a custom Stripe webhook event

Stripe, its docs and its tools are amazing, but today I found a shortcoming: it is not possible to easily send arbitary events to a webhook endpoint while having signature verification enabled.

So, I made this little script to make things easier:

You just need to adjust the webhook URL and secret, then point it to a json file containing the event you wish to send.

Thanks, as always, to a StackOverflow question.
