Which APIs you want to access beyond those provided automatically
If you'll be modifying the label image
the opened a case for me some days ago but now I just read here in the forum that M2 is not printing labels since 2018 with usps?
CAN SOMEONE CONFIRM if you can print shipping labels with usps API from magento without a third party plz?
After a long process with USPS they took around 2-3 weeks to complete the level 3 API. so now the option to print the label appear in the orders. note we don't have to do anything on magento to update the code or API or anything. just the basic usps setup is enough.
