Carrier for GLS

Justinholt.com Incorporated

Version 5.0.0

October 3, 2026
  • Initial release.
  • GLS through MyGLS for Croatia, Hungary, Czechia, Romania, Slovenia, Slovakia and Serbia, in production and on the MyGLS test system.
  • Labels in one call (PrintLabels) as PDF A4 (2 × 2 or 4 × 1), thermal PDF or ZPL (203/300 dpi), with multi-parcel shipments.
  • Reprints and bulk A4 sheets through GetPrintedLabels, and voids through DeleteLabels.
  • Cash on delivery, and parcel-shop and locker delivery (PSD).
  • Saturday delivery and FlexDelivery email/SMS notices.
  • Batch tracking (GetParcelListStatuses, 100 parcels per request) with full scan history, falling back to GetParcelStatuses on hosts without the batch method.
  • Daily sync of every GLS parcel shop and locker from GLS's public point map.
  • MyGLS error lists returned on HTTP 200 are read per method: a bad login is reported as such, and the duplicate-request guard (error 31) is treated as "may have been created", never retried.
