Have Media Mail or BPM options been added to GetEligibleShippingServices in MWS? They are available on the interface for sellers but last I checked 1 year ago they could not be accessed through an API call.
Not sure if they have. However the GetEligibleShippingServices is dependent on when the call is being made and the options being given. On top of all that you must also agree to the terms of service for each carrier for it to show up. So assuming that Media Mail would allow the item to arrive on time the call “should” include Media Mail.
It’s funny, the option appears in the front-end interface but not the API call. Isn’t Amazon supposed to be one of the best tech companies in the country?
That’s for AWS this is MWS.
Unfortunately, these options are not supported through the API at this time. Amazon is aware of this, however there is not yet an ETA for adding these options to the API.
