27 October 2026 orders

GET /v1/orders/{id}/label now returns PDF labels in a page size, and the default is A6 (105 × 148 mm) — the size label printers and adhesive AWB pouches take.

What changes#

• New size query parameter: a6, a5, a4 or original.
• Default: the size the seller chose in their Biklo settings, and A6 if they never chose. Until now you always received the courier's own PDF — usually an A4 sheet with the label printed twice. If your printing is set up for A4, send size=original (unchanged output) or size=a4.
• One parcel per page. Each distinct label is cut out and placed on its own portrait page; the duplicate copy couriers print on the same sheet is dropped, and every parcel of a multi-parcel order is kept.
• A4 and A5 print at real size (never enlarged); A6 fills the page.
• X-Label-Size response header with the size actually served. It reads original while label formatting is switched off on Biklo's side.
• An unknown size is 400 invalid_size. size does not apply to format=zpl.
