Amazon Buy Shipping API error when creating label


We have used ShipStation to create our Amazon integrated shipping label and packing sheets for both SFP and standard orders for the past couple of years, it is a great solution for us.


Amazon links directly to our Royal Mail account and Shipstation links to Amazon Buy Shipping as a carrier with all our shipping options available with our rates from Royal Mail.


My question is; does anyone else use this and have they had any issues with creating labels on ShipStation through ‘Amazon Buy Shipping’ recently?


This is the API error I am getting:

The shipping service specified does not exist or is not available for the specified parameters ie weight, dimensions. (Generic, Carrier Error Code: ShippingServiceNotAvailable). The selected delivery method does not offer the requested label format. Please choose a different label format or choose another delivery method which offers the requested label format. (Generic, Carrier Error Code: ShippingServiceNotAvailable).


I have not changed anything on either Amazon or ShipStation so I think it’s something that either of those has changed. I have been in contact with both Amazon and ShipStation, Amazon has passed it on to another team (as always for a slightly more technical issue!) which has not gotten back to me yet. ShipStation has said that they have other users experiencing the same issue and they have handed it to their dev team and will update me when they know (which could be weeks/months).


I am currently printing out the packing sheet on ShipStation and purchasing the shipping label directly on Amazon which is not efficient at all and takes me 10x the time it normally takes.



We are having issues as well since they sent an email yesterday reassuring us that the API is good - our Amazon orders will not load into Shipstation

I am having the same issue as danad, I keep receiving error messages when trying to refresh for new orders and support doesn't seem to be able to address this. They claim to have escalated my case, but I've heard nothing back as of yet. 


We're having the same issue. Keeping an eye on this thread for any updates.
