Magento 2 USPS setup
For Magento 1 Customers, refer to the following guide.
For Magento 2 Customers, refer to the following guide.
The steps are essentially the same between the two, the only major difference is where to find the shipping method setup.
You will need to set up a USPS account in order to get the API so Magento can communicate with USPS shipping methods.
In order to get the USPS API, you will need to set up a USPS account which you can do here: USPS Web Tools account. This account will provide you with the user ID and password that you can enter into their respective fields.
When the invoices are pulled down into POSIM, the shipping method that was selected will not show up anywhere except as a freight cost. To get the specifics on how to ship this invoice, you will need to locate the order on Magento, invoice it, and then ship it out with its tracking method.
