USPS wants us to use a standalone account, not the reseller account.
If this can't be done with Shipstation, we will have to move to different software.
Standalone USPS connections
Hey there @steve27,
You absolutely can connect your own direct USPS account! If you follow the steps found in this Knowledge Base article, you can certainly add your own Stamps account. While we offer that account to be utilized thru us, you are not required to use it.
I hope this helps! 🙂
