I noticed that Amazon Buy Shipping is now available in Shipstation (finally!!) but it doesn’t seem to work. When searching for carrier rates using Buy Shipping, I get an error back that says “One or more providers reported an error. Phone_number must be a string (validation).” Has anyone else seen this error and know of the fix?
I love Amazon Buy Shipping because the carrier prices that Amazon provides are the lowest available and it also protects my seller account from refunds and chargebacks, so it should pay for itself despite the $0.20 fee that Shipstation charges. Does anyone else have an opinion on using Amazon Buy Shipping with Shipstation?
