Database / BetterDB Interview questions

How do webhooks work in BetterDB Monitor?

When an alert condition fires – an anomaly, a capacity-forecast warning, or any other configured trigger – BetterDB Monitor can deliver it to a webhook endpoint you configure, such as a Slack relay, PagerDuty, or a custom internal service.

Each delivery is HMAC-signed, so the receiving system can verify a payload genuinely came from your BetterDB instance and wasn't forged or tampered with in transit, rather than trusting the network alone.

Deliveries are retried automatically on failure, and BetterDB keeps a full delivery log covering every attempt, so if an alert never showed up on the receiving end you can check exactly whether it was sent, retried, or failed outright, instead of being left guessing whether the problem was BetterDB, the network, or the receiver.
