After packing your items and organizing your box contents, the final step is submitting that information to Amazon.
There are two ways to do this in AccelerList:
1. 2D Barcode Method
Print a 2D barcode for each box (one click in AccelerList)
Attach it to your box
Complete the rest of the shipment in Seller Central
2. API Method
Submit box content directly through AccelerList
Complete placement, transportation, and labels inside AccelerList
👉 In most cases, we recommend the 2D barcode method because it’s simpler and requires fewer steps.
✅ When to Use the 2D Barcode Method
The 2D barcode workflow is best if you want something fast and flexible:
You usually ship 1 box at a time
You want a quick, simple workflow
You prefer finishing shipments in Seller Central
You want flexibility to move boxes between shipments easily
💡 Since each box has its own barcode, you can move it without reopening or repacking.
⚙️ When to Use the API Method
The API workflow is better if you want more control and optimization:
You use Amazon’s placement fee discounts (like 5-box splits)
You want to optimize how boxes are distributed across warehouses
You prefer completing the full workflow inside AccelerList
⚠️ Important:
If you’re trying to qualify for placement discounts, you’ll need to use the API method, otherwise Amazon won’t recognize your packing strategy.
