Add customer related data in packing slip
We would like to add customer related data in the packing slip.
The goal is to pull from our website customer related information (like the amount of points they have on the reward program we are running) and display that along with relevant data for that particular customer.
Because shipstation lacks this ability we were trying to add a dynamically created image by putting a url in the img tag that would return an image with the needed content.
<img src="https://domain.com/create-image.php?order=123456" />
