How do I add Bubble API_TOKEN to Stripe Webhook?

I am using Stripe for subscriptions and therefore would like to be notified when a customer’s monthly subscription payment has been successful. From the other forum articles, it seems the best way to do this is to set up endpoints in Bubble and Webhooks in Stripe, which I’ve been able to do successfully without authentication … but how would I add authentication? The Bubble documentation says to add “Authorization: Bearer API_TOKEN” to the header, but where and how in Stripe would one do that?

Currently facing the same problem. Any updates?

I think I go with the route of conditionals with specific info that I pass through Stripe and therefore will be available in the webhook.
