Automation
REST API for design renders (ZPL, PDF, PNG), all ZPL tools and batch jobs with usage metering, HMAC webhooks with a callback after render, tool, enrichment, batch and account API calls, push notifications, watch-folder printing, auto-reprint and AI agents that print labels without any labeling logic.
REST API
Automate your label pipeline with
api.zplcloud.com
Authenticate with an API key (X-API-Key or Basic Auth), render saved designs as ZPL, PDF or PNG, call every ZPL tool as an endpoint and run batch jobs that print straight to your printers - with usage metering and an optional webhook callback on render, tool, enrichment, batch and account calls.
All 22 ZPL tools as endpoints (/v1/tools/zpl-to-pdf…) - no rate limits, counted as renders- Batch jobs with up to 10,000 records on the Pro plan - sync or async with job status, printed in blocks to Weblink, remote or virtual printers, optional pick list PDF
- Optional webhook callback on render (PDF/PNG), tool, enrichment, batch and account endpoints (
webhookId), with or without the result - plus printers, agents and label quota via GET - Designs cached 60 minutes, invalidated on save or delete
- Body limits for ZPL rendering by design: max. 500 records, 1 MB per request
- OpenAPI / Scalar interactive docs at
/api/scalar - TLS 1.2 / 1.3, 12-character password policy, team roles Admin / Member

Every event where your team already looks
Print jobs, printer status and batch results trigger HMAC-signed webhooks with retry backoff (1 / 5 / 30 min) and a delivery overview - and render, tool, enrichment, batch and account API calls can report back to a webhook when they finish, with or without the result. Push notifications go out on seven channels from one UI; labels can be sent as e-mail attachments.

ZPL by e-mail
Send a design as zpl.prn attachment straight from the workflow.
Watch-folder printing
The agent prints every new .zpl/.prn file of a folder - oldest first, stability check, failed/ subfolder.
AI
Print labels from your app or your AI agent
zplCloud renders labels on demand - so your AI agent or app can create production-ready ZPL without any labeling logic. Send product data, get a printable label back.
- AI-ready REST API: describe the product, get clean ZPL, PDF or PNG - every ZPL tool is an endpoint too
- Works with ChatGPT, Copilot, Claude or your own agent
- Templates map your data to the right label - no ZPL coding
- Live PNG / PDF / SVG preview before anything is printed
Copy this prompt into an AI agent (ChatGPT, Claude, Copilot, Cursor …) - it reads zplcloud.com/SKILL.MD and builds the API print flow with a GTIN label for you.
AI → ZPL
POST /v1/zpl/render/design/42

ZPL guides
Free tutorials on barcodes, QR, fonts, graphics and print control at /guides.
Seven message buses
Kafka, Azure Service Bus, MQTT, AMQP 1.0, RabbitMQ, Amazon SQS and Google Pub/Sub. Stream subscriptions print automatically: JSON record → design → ZPL, or a ZPL envelope { schemaVersion, printer, zpl } straight to one or all printers. Nothing is acknowledged before the print; failures are redelivered instead of silently lost.
Object storage: S3 & Azure Blob
Print ZPL straight from a bucket - the message points at it instead of embedding it. And the other way round: printed ZPL is written back. S3-compatible, so MinIO, R2, Wasabi and Backblaze work too.
Output targets
After the print: store the label, send a message to a bus and trigger an HMAC-signed webhook - each step switched on separately.
