Alerts

Which problems send an alert, and where alerts go.

Alerts appear on the dashboard, and go by email (every plan) and to Slack (Pro and Multi) once you set them up under Settings.

What sends an alert

Stock update held by the mass-zero guard.
Keys rejected: the marketplace stopped accepting your API keys; sync pauses until you paste new ones. You get another message when they work again.
Sync stopped: no run has completed for an hour. A message follows when it recovers.
Critical mismatch found by the hourly check (for example an order missing in Shopify).
Stock refused by the marketplace for some offers, and orders that could not be imported.

The same alert is not repeated within 6 hours while it is still unread.
