Update the webhook endpoint
Only the fields you send are changed, except events, which replaces the subscription entirely. The URL must resolve to a public address — one pointing at loopback, link-local or private space is refused here and again at delivery time. Enabling without a URL is refused rather than saved. Requires webhooks:write.
