Get label information for an order
GET /orders/{tracking_number}/label
Retrieves labelling information for an order using the tracking number.
The labelling information for an order can only be retrieved after the order has been processed and allocated a courier, which can take some time after the order has been placed. If the order is yet to be processed, you receive a 422
Unprocessable response.
For more information about common labelling errors, and how to avoid label request timeouts, see the labelling section in the Developer Guide.
