The following question is related to Multi-Vendor.
I am looking for an add on the will allow admin and vendors to generate USPS shipping labels and once generated automatically will populate tracking number in the orders page and shipping page.
Currently I see an Endicia add on, which requires me to have a Endicia professional account so that I can access to the label server through the Add on. This is an expensive solution.
I am looking for a solution, where API provided by USPS can be integrated into CS Cart add on.
