LayerCrew Partner API

Your production line, as an API

You sell the parts; we print, pack and ship them under your name. Your system — a webshop, an ERP, a custom site — uploads the file, creates the order with your own reference and your customer's address, and hears back on every step: priced, accepted, in production, shipped with tracking, delivered. By signed webhook, or by polling one ordered feed.

• Free to integrate. No subscription, no minimum volume, no setup fee. You pay per order, at the per-part price the calculator shows, with the quantity tiers applied automatically.
• White label by default. Neutral packaging, your sender name, your card text, no invoice in the box.
• An engineer reads every order before it is accepted — the same design-for-manufacturing look every file gets.
• Test keys at once, from the moment you accept the agreement; live keys once we countersign.
• No SDK needed. Plain HTTPS and JSON. Every endpoint, field and error is in the reference and in the OpenAPI document.

How it works

1. 01

   Register your company

   Sign up at /developers/register and accept the integration agreement and the data processing agreement in your dashboard. Test keys are yours at once; live keys follow once LayerCrew countersigns.

2. 02

   Upload a file

   Declare the file, PUT the bytes to the signed URL, call complete. STL, OBJ and 3MF are priced automatically; STEP goes to an engineer through contact us.

3. 03

   Price it, then order it

   Ask for a quote, or create the order straight away: your own reference, the items, your customer's delivery address, your white-label instructions. Send an Idempotency-Key so a retry never creates a twin.

4. 04

   We price, review and accept

   The order is priced within minutes. An engineer accepts it, usually within one business day, or declines it with a reason you can act on. Payment instructions arrive with acceptance; on the default plan production starts once the transfer lands.

5. 05

   Follow it to the door

   Every state change is an event with a sequence number. Listen on a webhook, or poll GET /v1/events. Carrier and tracking arrive with order.shipped; order.delivered closes it.

Who it is for

Companies that take orders for printed parts from their own customers and want them produced without running a print farm: design studios, webshops, product brands, agencies, resellers. Partners are companies — a private individual orders through the calculator.

What you get back

• A price per item and totals in EUR, provisional within minutes and frozen at acceptance.
• Acceptance, or a rejection with a code and the engineer's note.
• Production status: in production, packed, shipped with carrier and tracking, delivered.
• An invoice per order, as a PDF link.
• A log of every request you made and every webhook we attempted — in your dashboard and over the API.

Start here

• Quickstart — from sign-up to a test order with webhooks.
• Authentication — keys, environments, rotation.
• Files, Quotes, Orders — the three objects you work with.
• Lifecycle and events and Webhooks — how you hear back.
• Errors, Rate limits, Idempotency, Test mode.
• API reference — every endpoint and field, generated from the spec.
• For machines: /openapi.json, /llms.txt, /llms-full.txt, and every page as Markdown at its URL plus .md — this one at /developers/index.md.
