# Label Generation Success, Sendle

> Label Generation Success for Sendle 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:** [Shipping & Courier](/nerve-centre/connectors#connectors-by-type)

## At a glance

> Share of Sendle label and order-creation requests that returned a usable shipping label on the first call over the trailing 24 hours. This is a despatch-bench health metric: when label creation fails, parcels cannot be booked, the pick-pack queue stalls and orders silently miss their dispatch cutoff. The card warns at `<98%`, a deliberately tight floor because even a 2 percent failure rate on a busy despatch morning means dozens of orders waiting on a manual retry.

## What it tracks

Label Generation Success is `COUNT(successful label/order creations) / COUNT(label/order creation attempts)` over the rolling 24-hour window, measured against the Sendle Orders API order-creation endpoint (`POST /api/orders`), which returns the parcel booking together with its label URL. A request fails when Sendle rejects it (invalid or out-of-zone destination address, missing weight or dimensions, an unservicable postcode, or an authentication or rate-limit response) and no label is produced. A sustained dip is usually one of three things: malformed address or weight data flowing from the store, an expiring API credential (cross-check [Days to Token Expiry](/nerve-centre/kpi-cards/sendle/days-to-token-expiry)), or a Sendle-side incident (cross-check [API Error Rate](/nerve-centre/kpi-cards/sendle/api-error-rate)). Because label creation sits at the very front of the despatch flow, a failure here pushes orders straight into a missed dispatch cutoff, so this card is an early warning ahead of [Late Shipments](/nerve-centre/kpi-cards/sendle/late-shipments). The `<98%` alert is the cue to check whether the cause is your data, your credential or Sendle's platform before the despatch bench backs up.

## Reconciling against the carrier's own dashboard

Cross-check failed bookings in the [Sendle Dashboard](https://www.sendle.com/) under **Orders** (and your own integration error log) against total creation attempts for the same 24-hour window; remember Sendle timestamps render in account-local time while our index normalises to UTC, so the window edges may not align exactly.
