Help with shipment creation API

Hi, I am working on a project that involves using the Easyship API to pull orders for our woocommerce store and then create orders. I know Easyship has this functionality already, but with the custom code we can do some other things that help our packing process run much more efficiently.

So far, I have everything working. My only issue is the orders that are created via the API do not allow me to generate a manifest. I suspect this is because they are marked correctly as drop off. We ship all of our shipments via USPS priority. I cannot find any documentation on getting this right so I thought I would ask.

SEcond question is regarding the status in Easyship. We use the API to create and then immediately print the label. Unfortunately, it appears in Easyship the shipment is not marked as shipped, and as a result the customers tracking info is not updated unless they go through to view the USPS tracking number directly.

Any ideas to get these both fixed. Here is an example payload we are sending to the API. Help would be greatly appreciated.
