Stripe Payments

First, configure the STRIPE_PUBLISHABLE_KEY and STRIPE_SECRET_KEY settings, with the API keys from the Stripe dashboard.

To receive payment confirmation from Stripe, we need to receive a webhook from them.

For local development, you can receive this with the stripe CLI:

$ stripe login
$ stripe listen --forward-to
> Ready! Your webhook signing secret is whsec_I_AM_A_SECRET_KEY (^C to quit)

Configure STRIPE_ENDPOINT_SECRET with the secret key provided by stripe-cli listen.

For production use, configure a webhook in the Stripe dashboard. The endpoint should be https://my.debconf/invoices/stripe-webhook/. Listen for charge.dispute.created, charge.refunded, and payment_intent.succeeded. Again, STRIPE_ENDPOINT_SECRET should be configured to the webhook's signing secret.
