# Label Generation Success, Shippo

> Label Generation Success for Shippo stores. Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it.

**Metrics type:** [Supporting Metrics](/nerve-centre/overview#metrics-types-explained)  •  **Category:** [Operational Health](/nerve-centre/connectors#connectors-by-type)

## At a glance

> Share of Shippo label-purchase requests that returned a valid shipping label (transaction status `SUCCESS` with a populated `label_url`) rather than an error, over the trailing 24 hours. This is the despatch desk's heartbeat: when label generation stalls, parcels cannot leave the building and the dispatch SLA clock keeps running.

## What it tracks

This card reads **Label Generation Success for the selected period** over a rolling `24H` window. The denominator is every Shippo transaction request (a label purchase against a selected rate); the numerator is the count returning transaction `status = SUCCESS` with `messages` empty and a `label_url` populated. Failures surface as transaction `status = ERROR` with carrier-returned `messages`, most often invalid or undeliverable address, carrier account inactive or unauthorised, insufficient postage balance, or an upstream carrier API timeout. Because Shippo brokers labels across many carriers, a dip here is usually carrier-specific or credential-specific rather than a Shippo-wide outage, so read it next to [Label Failure Rate by Carrier](/nerve-centre/kpi-cards/shippo/label-failure-rate-by-carrier) to see which carrier credential needs attention, and [API Error Rate](/nerve-centre/kpi-cards/shippo/api-error-rate) to separate carrier rejections from transport-layer 5xx errors. The alert fires below **98%**, because even a 2% failure rate on a busy despatch morning leaves dozens of parcels stuck in the queue. A sustained drop also feeds the real-time [Label Print Failures Spike](/nerve-centre/kpi-cards/shippo/label-print-failures-spike) alert, which pages the despatch team within the hour.

## Reconciling against the source

Compare against the Shippo dashboard **Shipments** view, where failed transactions are flagged, and against the Shippo transactions list in the API (count where `status` is not `SUCCESS`). Carrier-side rejections also appear in each underlying carrier's own shipping portal; Shippo records transaction timestamps at request time in carrier-local time, so a 24-hour reading can shift slightly against a portal reporting in a different timezone.
