Map Shipping Carrier Names (API Aliases)

When using third-party services to generate shipping labels or update tracking data via API, the carrier names they use may differ from AST’s built-in carrier names. To ensure consistent matching, you can map alternate names (aliases) using the Custom API Name field.

🧩 Why You Need This

Third-party services might refer to a carrier differently than AST.
For example:

• Your shipping system may call it: “USPS Priority”
• AST lists it as: “USPS”

Without mapping, AST won’t recognize “USPS Priority” as the same carrier, which can lead to tracking data not syncing properly.

🔧 How to Map a Carrier Alias

1. Go to WooCommerce > Shipment Tracking > Shipping Carriers
2. Find and click the three-dot menu on the carrier you want to map (e.g., USPS)
3. Click Edit
4. In the Edit Shipping Carrier sidebar:
   • Locate the Custom API Name field
   • Enter the alias used by your third-party system (e.g., USPS Priority)
   • Use the ➕ (plus) icon to add more aliases if needed
5. Click Update to save your changes

💡 Notes

• Aliases must match exactly the name used by your API or CSV source.
• You can map multiple aliases to the same carrier.
• This ensures that any tracking info imported using an alias will be correctly linked to the intended carrier.
