How to create postage_label's via the api?

[Braedencraig]

Hey there!

Sorry if this is a dumb question, but i'm a little confused on how to go about creating postage_labels for specific shipments!
When I create a shipment, I see the fields, postage_label_png_url, and postage_label_zpl_url are null. Is there an extra step I am missing in order to create those labels properly?

Labels are only available if the shipment has been purchased and in some cases not received. If your shipment is purchased and not received by Chit Chats and you aren't seeing a label URL then reply with the shipment ID and if it's on staging or production and somebody can investigate as you should see a URL in that scenario.

Thank you so much for the help!
