This would be a game-changer for us if we could do this. Adding this would allow us to offer a discount post-purchase to increase cart values.
What's most annoying about all of this. I understand how to work with API's and I can code in python. I figure out 2 simple ways this could be done on their end, using their system.
Yet, 1 variable they change from 'read-only', allowing me to merge to IDs together for one order, even though it does the same thing when two orders are combined manually.
The other was going to use the manual store, and then use eBay's api to notify what the tracking numbers where when the labels were created, but it doesn't appear their api allows for batching like their normal interface does. So it would take longer having to go through each individual label, as well as packing slip then it would be to just manually combine them anyway.
It's almost as if they want to force us to use their interface even though there to my understanding isn't any reason why either tool I have created should be able to work. Shipstation, I'm down to my last straw with this. I should haven't to combine 50 orders every Sunday night for Monday's shipments. I'm already doing too much. Please fix this.
