abc123, you can send to /abc123/stripe/events or any other path.POST /new creates an inbox and returns JSON. GET /api/inbox/:id/requests returns all captured requests as JSON. Use the ?since=LAST_ID parameter to poll for new requests only.[truncated] note. This is enough for the vast majority of webhook payloads.
