# "first-shutdown" ping

This ping is a duplicate of the main-ping sent on first shutdown. Enabling pingsender
for first sessions will impact existing engagement metrics. The `first-shutdown` ping enables a
more accurate view of users that churn after the first session. This ping exists as a
stopgap until existing metrics are re-evaluated, allowing us to use the first session
`main-pings` directly.

See {doc}`main-ping` for details about this payload.
