Xendit Invoice callbacks — the shared account's ONE invoice URL.

Canonical URL (set in the Xendit dashboard): https://api.intura.co/v1/platform/webhook/xendit/invoices /xendit is the same handler, kept for deliveries configured before.

Verify, then route (see xendit_forward): another app's invoice is passed on untouched and its answer decides ours (2xx -> 200, else 502 so Xendit redelivers). Ours runs like the Airwallex route: claim the event, run the idempotent handler, and answer 200 for anything past verification so a bug of ours is not retried on Xendit's schedule.
