Stripe Test Webhook

I am currently looking into how one should use the test mode in Stripe for a proper setup, but when configuring it I've spotted that you're only able to configure secrets for the Account & Connect webhooks. Not for a third test webhook.

@fermentfan I was able to run my webhook locally but in the Stripe Dashboard the test endpoint seems to return 403. I imagine it has something to do with the stripe-signature, have you experienced some problem with it too?

Edit: nvm, it was a configuration of the devops -_-
