@SuperMgr-Sarah No status? How about changing this to "Planned"?
Quite frustrating to see basic things like this requested but never implemented for almost 4 years.
To echo @ryan5 , this endpoint is needed thanks to the ReCaptcha being re-added to shipstation login.
Surely a GET endpoint like /packingslip/<orderId>?packingSlipTemplateId=#
can't be that hard to add...
