Create label download link through API

I have seen some other threads related to generating a download link for a label. I currently use another ship API to generate the label and it creates a download zpl link just fine. My issue is that it does not have a way to update Amazon order of the tracking and auto confirm the order unless its Amazon Buy shipping.

I am looking at two possible solutions. Is there a way to create a zpl file link so then I can create label in Veeqo instead of the other shipping API? If not can I continue to create the zpl file link in the other API, but use Veeqo to update the order with a tracking number and confirm the order in Amazon?


is there no way to download the label file via API?
