Setup and reference for the public API, CLI, Docker agent, Weblink certificates, CloudToBrowserPrint, Print Views and integrations.
zplCloud CLI & remote agent

One binary for macOS, Linux, Raspberry Pi and Windows: apply printer profiles, send raw ZPL (TCP 9100 / USB), provision Weblink certificates, run the outbound proxy agent, watch-folder printing.

CLI as Docker container

Multi-arch image docker.zplcloud.com/zplcloud-agent (amd64/arm64): docker-compose.agent.yml, environment variables, USB passthrough, update and troubleshooting.

Weblink certificates (Cloud Connect)

One-liner deploy of WEBLINK2_CA/CERT/KEY.NRD via ~DYE over TCP 9100, SGD slot configuration (weblink.ip.conn2.location, NTP, RTC), printer reset. PowerShell and bash.

CloudToBrowserPrint

Local print service on 127.0.0.1:9100 for Windows, macOS, Linux and Raspberry Pi: device discovery, raw/URL/file printing, PDF/Office/image → ZPL, barcode decoding, bidi (TCP/serial/BT/LPT/IPP), JS client.

Print Views + PWA

Protected label URLs under print.zplcloud.com: form designer (text/select/checkbox/button), QR/barcode scanner, lookup, PDF preview, Weblink printing, PWA manifest + service worker per view.

Connectors

Databases, message buses and object storage: connection strings, envelope formats and output targets.

Integrations

DHL / Deutsche Post INTERNETMARKE with your own DHL credentials and Portokasse: buy stamps as PDF or 203-dpi ZPL via REST, DHL-only Print Views with SQL lookup, transaction log with voucher IDs.

Public API

Authentication with API key or Basic Auth, request IDs and error format, render counting against the label quota, and the optional webhook callback with or without the result on the render, tool, enrichment, batch and account endpoints.

Rendering, enrichment & batch jobs

Render designs as PDF or PNG, add your own fields to carrier ZPL, and run batch jobs synchronously or asynchronously with printing, pick list PDF and job status.

ZPL tools API

Every ZPL tool from the website as a REST endpoint: ZPL to PDF/PNG/SVG, linter, analyser, PDF/image/SVG to ZPL, barcodes, QR codes, GS1 and barcode check. No rate limit, counted as renders.

Printers, agents & quota

List printers and CLI agents per API key or for the whole company, check the monthly label quota and list your webhooks with their IDs.
