# rivr verify checks a quick answer and names its checks

- Date: 2026-10-28
- Type: New
- Surface: Developer portal and CLI
- What you need to do: Nothing.
- Address: https://developers.rivr.io/changelog/2026-10-28-cli-verify-v1

`rivr verify` (CLI 0.4.0) runs six checks against your own webhook receiver instead of five. The new one, fast response, sends a second new event with its own `Rivr-Webhook-Id` and expects `2xx` within the time Rivr waits (5 seconds, as the guide Receive webhooks says), so a receiver that does its work before it answers is caught. When every check passes, the statement you can quote names the checks that ran (signed delivery, duplicate delivery, wrong signature, stale timestamp, missing signature, fast response), and `--json` lists them under `checks`. Nothing is sent to Rivr: the checks go only to the address you give. Run the install command again to update.
