Troubleshoot: FBA Orders Not Downloading in Webgility Desktop (Amazon API Throttling)

When a range of FBA orders is missing in Webgility Desktop and QuickBooks sales stop matching Amazon Seller Central, the most common cause is Amazon API throttling on the FBA fulfillment endpoint. Batch and date-range downloads fail silently, but downloading a single order by its Amazon Order ID usually still succeeds. Use that difference to diagnose and work around the issue.

Step 1: Confirm which orders are missing

In the Amazon sales channel, list the FBA orders present in Webgility Desktop for the affected date range. Cross-check against the Amazon Seller Central Orders report for the same range. Note the missing Amazon Order IDs.

Step 2: Try a batch download first

Go to Connections > Sales Channels > Settings. On the Download Settings tab, set the start date to just before the earliest missing order, click Save & Continue, and run Get New Orders from the dashboard. If the batch download completes but the missing orders still do not appear, throttling is likely.

Step 3: Download by Order ID

 

Use Get New Orders > Orders by ID from the dashboard. Paste one of the missing Amazon Order IDs and download it individually. If this succeeds while the batch download did not, Amazon throttling on the fulfillment endpoint is confirmed. Repeat this per missing Order ID as a workaround until the throttling window clears.

Step 4: Space out your download requests

While throttling is active, avoid repeated batch downloads. Amazon reduces the throttle when request volume drops. Wait at least 30 minutes between batch attempts and reduce the download date range to a shorter window (for example, one day at a time).

Step 5: When to contact Webgility Support

If per-Order-ID downloads also fail, or if throttling persists for more than 24 hours, contact Webgility Support with the Amazon Order IDs of the missing orders and the exact time you attempted the batch download. Support can review backend logs and coordinate with Amazon Seller Support if the throttle window is unusually long.
