Outbound fetch

fetch() only reaches hosts explicitly listed in the outbound allowlist.

Configuration

"outbound": ["api.stripe.com", "hooks.slack.com"]

Usage

const res = fetch("https://api.stripe.com/v1/charges", {
  method: "POST",
  headers: { authorization: "Bearer " + env.STRIPE_KEY },
  body,
});
