We noticed recently (in October 2025) that Amazon’s API intermittently returns no Amazon-Partnered options when you click the Generate Transport Options button.
Getting the Immediate Issue Solved
We've found that the best options to solve are:
Generate Transport Option for a different placement, or
Click the Regenerate Option button for the selected placement.
Retrying a few times usually solves any issues that pop up.
Here's an example. I initially generated transportation options for the first placement option, but Amazon only provided non-partnered shipping carrier options.
I later tried previewing the transportation optiosn for the second placement option (shipment going to PBI3), and as you can see below, Amazon indeed offered the Amazon-Partnered UPS transportation option.
You'll also find the Re-generate options button in grey. You can click this button to generate a new set of transportation options.
In our experience, we've found that retrying Re-generate options a few times does make a difference. If you have a preferred fulfillment center, you may find this helpful.
Preventing the Issue Going Forward
If you find that you run into this issue frequently, you may find it helpful to switch to 2D barcodes for box content submission method.
