Outage Description
SKULabs has detected that Amazon's MWS API is currently experiencing internal errors. Affected services include:
Stock sync (Inventory feed API)
Mark as shipped (order fulfillment feed API)
Listings sync (Reports API)
What should I do?
SKULabs is designed to automatically scale back sync for your store when there are detected outages. SKULabs will automatically resume sync as soon as recovery is detected.
Actions items for your team include:
Monitor sales on Amazon store to prevent potential overselling.
Mark orders as shipped directly on Amazon for orders that are due to be shipped before Amazon restores service.
Once service is restored, resend Mark as shipped notification for orders not marked as shipped.
Will I oversell?
If you have a large number of sales on other channels that track the same warehouse as your Amazon store there is a chance you can oversell during this outage.
It is recommended to keep a reserve of inventory that can hold you over for up to 24 hours of sales if you want to completely avoid the risk of overselling.
Amazon for instance will not even open a ticket for you with regard to inventory feeds taking less than 24 hours to process. Such 24 hour inventory feed outages are common during peak season (November-January). Speak with SKULabs support to build your inventory reservation strategy using rules and reserve warehouses to prevent overselling.
Should I contact SKULabs support?
If there are any questions please reach out through the in-app conversation system as we will not have additional details by phone.
Should I contact Amazon support?
Contacting Amazon Seller Central support while a posted outage is live is not recommended until Amazon recommends you to contact them directly if you're still having issues.
Check the status page on Amazon's website for updates on when you should reach out to Amazon if you're still having connectivity issues.
