Hi everyone, apologies for the delay in updating this request! In case you missed it, Starshipit now supports USPS (via Direct API), allowing you to connect your own USPS enterprise account without going through EasyPost.

The direct integration supports US domestic shipments. You'll need your USPS enterprise account details and authorisation for Starshipit.

See our setup guide here: https://support.starshipit.com/articles/5767391395855-set-up-usps#configure-usps-through-direct-api

Thanks for your patience and feedback!
