USPS Info
You were correct, the link you guys give to the USPS website is a little vague, what I suggest is to use this address webtools/ . This address takes you directly to the part of the site where you set up the correct username to use the API that is provided in your software . On the main USPS site, you can set up a username/password as a business to ship with as well and is a little confusing. Thank you for pointing me in the right direction, we're all good now.
