In order to use the United States Postal Service (USPS) to provide shipping rate calculations for purchases. We require that you sign up for a free USPS Web Tools account, and obtain the required API key.

Obtaining your API Credentials
The confirmation email you receive from USPS will contain a username and password to use. However, you will need to contact USPS for “Production Server Access” before these credentials will work.
In the confirmation email, locate and record the Username.
You will need to provide these credentials to Sniperdyne .
Obtaining Production Server Access
In order for your product to be able to use the shipping rate lookup feature, you will need to request that USPS provide you with production server access.
- Send an email to icustomercare@usps.com with the following information.
Subject: Production Server Access
Email Body: I am using Nomad eCommerce to provide an online store that includes a shipping rate lookup through USPS. In order for Nomad eCommerce to use this feature, I will need live production server access instead of the testing access I have so far. My Username is 'Enter Username from Confirmation Email'
It may take a couple of days to receive a response, but once USPS moves your account to their production server, your shipping rate lookup should work with the credentials you received in the confirmation email.
