Download label

Download a label by carrier and tracking number.

The response includes the tracking number along with the label in PDF, image, or ZPL format, based on the media type specified in the Accept header.

For example:

• Accept: application/pdf returns a PDF label.
• Accept: image/png returns an image label.
• Accept: application/zpl returns a label in Zebra Programming Language (ZPL) format.

When using application/zpl or application/pdf as the Accept content types, it is recommended to include application/json as a secondary content type to receive error messages.
