ShipStation

Connect your existing ShipStation account to see recorded label costs, carrier use, and delivery metrics in Nummbas.

Connection Method

ShipStation V2 API key — Create the key in your ShipStation account and paste it into Nummbas. Nummbas uses the key only to read your shipping data.

How to Connect

  1. Go to Dashboard > Integrations
  2. Click Connect on the ShipStation card
  3. In the modal, follow these steps:

Getting Your ShipStation V2 API Key

  1. Sign in to ShipStation
  2. Open Settings
  3. Go to Account, then API Settings
  4. Generate or copy the V2 API key
  5. Paste the key into Nummbas
Tip

ShipStation allows one active V2 API key at a time. Generating a new key can stop other tools that use the current key. Copy the current key when it is available.

Entering Your Key

Paste the ShipStation V2 API key into the Nummbas modal and click Connect.

What Gets Synced

Shipping Metrics (90-day period)

  • Completed outbound labels
  • Recorded label and insurance spend
  • Average recorded cost per label
  • On-time delivery rate
  • Average transit days
  • Carrier breakdown
Note

ShipStation label costs are the amounts recorded when each label was created. Later carrier adjustments or charges paid outside ShipStation may not be included.

Features Powered by ShipStation Data

  • Business Insights — shipments, average cost per shipment, and total shipping spend so you can track how much fulfillment is costing your business over time
  • Expense Intelligence — shipping costs automatically appear as an expense category, making it easy to see what percentage of your revenue goes toward getting products to customers
  • Insight Rules — automated alerts when your on-time delivery rate drops below healthy levels or when your shipping costs per order are higher than expected, so you can act before customers start complaining
  • Business Reports — shipping cost analysis included in relevant reports, helping you spot trends like rising carrier rates or shifts in where your customers are ordering from

Troubleshooting

  • Connection failed — Check that you copied the V2 API key from ShipStation > Settings > Account > API Settings. A ShipEngine key will not connect this integration.
  • Data not appearing after connecting — The initial sync can take a few minutes. Check the integration status on the Integrations page to confirm the sync is in progress. If your ShipStation account has no recent shipments, there will be no data to display.
  • Stale or outdated numbers — Nummbas refreshes your shipping data automatically. You can start a manual refresh from the Integrations page.
