Starting July 5th, Shopify’s Amazon sales channel stopped transmitting fulfillment and tracking information back to Amazon, affecting hundreds of sellers with thousands of orders.
Core Issues:
Fulfilled orders in Shopify not updating to Amazon as shipped
Tracking numbers not syncing, causing late shipment penalties
New inventory listings failing to publish to Amazon
Inventory quantity syncs also affected, creating overselling risks
Impact on Sellers:
Late Shipment Rate (LSR) violations reaching 27%+ despite on-time shipping
Risk of account suspension and deactivation threats
Dramatic sales drops (up to 95% reported)
Manual workarounds requiring hours daily to copy/paste tracking data
Root Cause:
Amazon reportedly changed API requirements in February; Shopify failed to update
Both companies blaming each other when contacted for support
Shopify provided no timeline for fixes, suggesting paid third-party apps instead
Temporary Solutions Used:
Manual tracking entry via Amazon’s bulk upload spreadsheet
Shipping directly through Amazon to keep data on one platform
Using apps like Matrixify to export tracking data
Resolution:
Issue fixed after approximately one week (mid-July)
However, LSR damage persists as Amazon refuses to adjust metrics retroactively
Future Concern:
Shopify announced discontinuation of the Amazon sales channel effective September 20-27, 2021, requiring migration to paid partner apps ($600-800/year). Sellers exploring alternatives like Amazon Integration Plus ($20/month), Sellbright, and other multi-channel solutions.

Ugh, fellow seller here: same issues it seems – issues happening 7/5 thereabouts and 100s of orders not updated:
Shopify inventory → FBM inventory – not populating
Amazon FBM orders → Shopify orders – not populating
New Shopify listings → FBM listings – not populating
I’m open to paying for a solution just to save an hour a day of manual updates by my warehouse – do any SELLERS have a good rec on an easy-to-use app? (Also ITT: garbage app developers pitching nonrelevant apps for views wish I could downvote them.)
Wow! Everyone who is having some trouble with this issue might want to check your inventory. Along with everything else, it looks like Shopify is not updating inventory quantities to Amazon either. If you sell an item on your Shopify store, it does not then update the quantity to Amazon, which leaves you in danger of overselling. BAD BAD BAD.
Just got off the phone with Shopify support. While they didn’t have any actual answers, at least this time they acknowledged that there is a problem. I would encourage anyone who is having issues to post here so they can get an idea of how widespread this is. It seems that the problems are all in Shopify sending info to Amazon, but Amazon can send info to Shopify no problem.
IE, Amazon to Shopify seems to work ----> Orders on Amazon get sent to Shopify. No problem.
Shopify does not send fulfillment data to Amazon to mark orders as fulfilled.
Shopify is not sending data to Amazon to list new inventory items (everything is stuck in pending forever)
Shopify is not updating inventory quantities. If you sell something on your website, inventory on Amazon does not get reduced. I would assume that if you restock an item, and increase your inventory, that will also not be correctly updated. THIS ONE IS CRITICAL, YOU RUN THE RISK OF OVERSELLING.
Word on the Amazon forums is that Amazon changed what is needed for their API, they told Shopify about this in February and nothing happened.
It does seem like a Shopify issue, if you think about it. It’s not passing on the information generated on the Shopify side.
I, too, am having the problem with tracking and ship date information not being passed to Amazon. Now I have late shipments and I am in violation of Amazon policies and thus, may be deactivated.
Even after manually copy and pasting tracking information, it STILL says my shipments are all late. I have no idea how to fix it. Even though the ship by and ship date match, it’s saying that they are late. My guess is that Shopify is passing something through AFTER I manually corrected it on the Amazon side.
Gidget thats what I am experiencing. I am putting in the tracking and the date shipped into Amazon manually and its showing shipped late. I am literally having an argument via an Amaon support ticket with their team why this is NOT my fault.
Our sales have been dramatically affected as well. Plus, our ads don’t seem to be showing since we were threatened with deactivation. We are paying a company to manage these ads so this is very frustrating. I’m a little worried that our 30-day LSR will continue to deteriorate since our sales are a fraction of what they once were (ie the denominator is going to get smaller but the late shipments will not improve until the 30 day window has passed.)
For anyone who facing an issue with update the tracking code, one possible solution will be uploading the tracking code via Excel upload. It’s still required manual operation but could be better than doing this one by one
and one more person with the same issue of the shipping confirmation not making it back to Amazon, who then complains that I am shipping late, despite having shipped many days ago.
Same issue. Just started over July 4th weekend. Amazon is being extremely difficult in resolving the LSR damage. One rep has said they are aware of the issue but I need “concrete proof” to show her that my shipments were not late. Half my shipments were delivered already before I even realized on Wednesday the shipping info was not updated.
More word’s from Amazon “Also if the fault lies with shopify as a final result the metrics will not be updated as they represent your company for the metrics as the service used. It does not actually matter when items were actually shipped, it matters what caused the orders to be marked late which was failure to ship items on time which lies with the XML file upload and response message. As if they got an error in the respose and choose to ignore it and say to you that all was updated that shopify’s fault not Amazon’s.”
So Late Shipping Rate has ABSOLUTLY nothing to do with when it actually shipped. yeah that makes tons of sense.
I jst keep reopening my case with Amazon. As soon as I do they close it with some BS. I just keep asking them to acknowledge they are aware of the problem and that my orders did ship on time. If I can at least get that, if I get suspended I have something in writing to fall back on.
If you have never been through a suspension I can tell you it is a terrible process to get reinstated. I have twice and both times were for completely BS reasons. I am 100% positive is was caused by my one and only competitor.
Ok, so we know that Amazon won’t help us and Shopify is being stubborn about recognizing and fixing it. So, what can we do?
I am going to start shipping from Amazon (unless the rates are outrageous) to keep it encapsulated on their platform. I manually entered ship dates that were truthful, correct and within their ship by day, but since I added them a day AFTER the ship by day, they were counted as “late” OR shopify went behind my back and changed them, somehow.
So… at the risk of really screwing up my inventory system, I may turn the Amazon API off on my shopify store. If that’s what needs to happen, I shall do it.
Does anyone else have any other ideas or solutions? I don’t think opening tickets or complaining will do anything. Amazon has a tight grip on us… we follow or fail.
Sidenote… Shopify launched their bulk shipping thingamadoo the same weekend we started having Amazon problems. I wonder if that’s where the issues emerged from.
@gidgetgadget your side note is interesting. My life experience has been when there are technological issues its always because something else has changed and no one realized that change affected another part.
Where I purchase my postage isn’t that big of a concern for me, all the platforms seem to have the sample pricing. Tracking my inventory across multiple marketplaces is my biggest concern.
I received this from Shopify support. Thought I would share for possible interim solutions.
I received a response from our tech team. They said the following:
““Our Amazon channel is experiencing a few technical issues and we aren’t able to provide a timeframe for resolution at the moment. Given the importance of this integration, I’d recommend looking at some of our apps supported by third party developers. Our partners have teams dedicated to working with Amazon’s updates, so they are less likely to run into similar issues”. We are currently working with few partners on new Amazon sales channels and we would be happy to offer you early access. You can find these partners here:
Same here, Shopify wants me to sue a 3rd party $20 fee product to solve their problem. Pretty sad considering Shopify is rich in equity $1500 per share stock price. Throw money at this and fix it asap or risk loosing customers. Are they clueless?
Takes very little extra time to ship in shopify and keep the amazon seller central orders page open at the same time.
I am shipping through 3rd party endicia postage which copies tracking number into clipboard, then just paste it into the shopify confirm order and the same with amazon confirmed order. Just one more step. You really want to do this so you can continue to capture the data on the shopify side for customer service.
If you do a lot of business on both platforms you may want to call the shipping on you amazon orders something different so you can sort by shipping type then order date, this way everything lines up perfect on both platforms. What a pain.
Both companies have the need to resolve this issue as it creates problems for us on both platforms. No way in hell I am paying more to a 3rd party to solve this issue.
You may want to add a day to processing time in Amazon until we get a handle on this.
I am doing a split screen and highlight - drag over to the Amazon page. It drags the shipping price with it so I have to back space 5 times to delete it. Im getting pretty damn fast at it!
I m doing about 100 Amazon orders a day. I have found that filtering my orders from Amazon and doing all those labels together lines them up pretty well then I just match by name. I am also taking time during the day to batches of labels rather than all at once which seems less fatiguing on my eyes and brain. I dont know why but highlighting and dragging for an hour wears me out!
Begs the question, if Shopify can’t provide the service we are paying for, should we be receiving a discount?
wish I could downvote them.)
