You are talking about 2 completely different interfaces.
Are you attempting to get Stamps.com functioning so that Stamps.com can download your order details?
STAMPS.com is requiring me to add new code to my zencart site so that it can pull orders from my site, upload to stamps/shiprush and then print postage, and then feed back to my site the updates and shipping details.
I believe stamps has been bought out by shiprush?

Are you attempting to get ShipStation functioning so that ShipStation can download your order details so that you can use your Stamps.com account to pay for the postage?
You mention Stamps.com which owns ShipStation but the interfaces are completely different. You also mention ShipRush which develops the Stamps.com code but has nothing to do with the ShipStation code.
We switched from the Stamps.com coded interface to the ShipStation interface due to Stamps.com not being able to satisfactorily support their code because they do not write it. The ShipStation interface is much more user friendly, an easier install and also includes Express1 USPS account in addition to Stamps.com USPS account. One is less expensive than the other in some instances due to different contracts with the USPS.
We did create a separate admin account/password for ShipStation and restricted access but there was never an issue before or after. We have never had an SSL issue using the ShipStation interface.
ShipStation support is lightyears ahead of Stamps.com support but is webbased/email only (no telephone) -
I will look into shipstation for code. This is insane!
If by some chance you are using an older, saved, shortcut for the ShipStation webapplication (
