Clear the bed programmatically from your own system

API & webhooks: drive AutoPrint from your own automation

Smart Pro Plan

When you have your own way to clear the bed - a robot arm, a PLC, a vision system, a sensor, a whole factory line - SimplyPrint gets out of the way. AutoPrint waits, your system clears the part, then tells SimplyPrint the bed is clear via the API or a webhook, and the next queued job starts.

Your hardware clears the bed, SimplyPrint runs the queue

Built for custom robotics and factory automation: AutoPrint handles the printing and the queue, you handle the physical clear, and a single API call or webhook hands control back so the line never stops.

What is the API & webhooks clearing method?

API & webhooks is a clearing method for AutoPrint where your own system clears the bed and then tells SimplyPrint the bed is clear, so the next queued job can start. SimplyPrint doesn't physically clear anything here - it waits. When a print finishes, AutoPrint pauses on that printer until your automation - a robot controller, a PLC, a vision system, an external sensor or a factory line - removes the part and signals back. That signal comes one of two ways: API, where your system calls SimplyPrint to mark the bed as clear, or webhook, where SimplyPrint notifies your system that the print is done so it can clear and report back. Either way, the moment the bed is marked clear, the next job in your queue begins.

API or webhook: which should I use?

Two ways to wire your automation to AutoPrint. They cover opposite directions of the same handshake.

API: you call us

Your system already knows when the bed is clear - a robot finished its cycle, a sensor confirmed an empty plate. Have it call the SimplyPrint API to mark the bed clear, and AutoPrint starts the next queued job.

Webhook: we call you

Let SimplyPrint notify your system the instant a print finishes. Your line reacts, clears the part, then marks the bed clear so the next job can begin - no polling required.

How it works in SimplyPrint

Wire it up once and your custom line keeps clearing itself between prints.

Connect your printer and enable AutoPrint

Add any printer to SimplyPrint, enable AutoPrint on it, then pick API & webhooks as the clearing method.

Queue your jobs

Fill the print queue. Smart matching sends each job to a printer that fits, so the right print lands on the right machine at the right time.

Your system clears and signals

When a print ends, AutoPrint waits. Your automation clears the part, then marks the bed clear via the API or a webhook - and the next queued job starts.

See it in SimplyPrint

Turn on AutoPrint, let smart matching pick the next job, and hand the physical clear to your own system.

Flip AutoPrint on for a printer and choose API & webhooks as its clearing method.

Smart matching

Matching criteria decide which queued job runs next on which printer, so your automation only ever has to clear and signal.

Works with any printer

Most clearing methods depend on specific hardware. This one doesn't. Since your own system performs the physical clear and reports back, the API & webhooks method works with any printer SimplyPrint can drive. SimplyPrint handles the printing and the queue, your automation handles the clear, and the API or webhook is the bridge between them - so it fits anything from a single bespoke rig to a full factory line.

Built for custom robotics and factory automation

Where programmatic clearing earns its keep.

Robot controllers

A robot arm or gantry pulls the finished part, then calls the API to mark the bed clear and trigger the next print.

PLCs and sensors

A PLC or an external sensor confirms an empty plate and signals SimplyPrint, keeping a production cell running unattended.

Factory lines and vision

A vision system or conveyor verifies the bed is clear, then a webhook handshake lets AutoPrint roll straight into the next job.

Nothing to buy - it's built in

API & webhooks is a built-in SimplyPrint clearing method, so there's no hardware add-on to purchase from us for the method itself. Enable AutoPrint on your printer, choose API & webhooks as the clearing method, and wire your automation to the API or a webhook. For request and event details, head to the SimplyPrint developer and API docs - we keep the exact endpoints and payloads documented there rather than on this page.

Frequently asked questions

Any printer SimplyPrint can drive. Because your own system performs the physical clear and signals back, there's no printer-specific hardware involved - the method works the same whether you're running one custom rig or a whole factory of machines.
As many as your queue holds. After each print, AutoPrint waits for your system to clear the bed and mark it clear via the API or a webhook, then starts the next queued job - repeating until the queue is empty.
Not from us for the method itself - API & webhooks is a built-in SimplyPrint clearing method that runs through AutoPrint. You provide your own clearing hardware (a robot, PLC, vision system or sensor), and you'll need an AutoPrint license for each printer.
It's the direction of the handshake. With the API, your system calls SimplyPrint to mark the bed clear. With a webhook, SimplyPrint notifies your system that the print is done so it can clear the part and then report back. Use whichever fits how your automation is built - both end with the next queued job starting.
Yes. API & webhooks is just the clearing step in the AutoPrint loop. Jobs come from your print queue, smart matching picks a fitting printer, and once a print ends and your system marks the bed clear, the next queued job begins automatically.
