Can I change carrier name "Stamp.com" to "USPS" instead?

[Balkobot]

I have a API selling channel unable to identify shipping carrier "STAMP.COM" as USPS carrier. Would that be any method that we can change my USPS provider name and method  from "STAMP.COM" to "USPS" instead in our API setting? Here's the request from our selling channel. Please help.

Please kindly revise your incorrect shipping carrier and method from you API system.

Any update or suggestion here?
