Integrating Wireless Pick-to-Light with Your WMS via REST API
Voodoo Robotics pick-to-light integrates with any warehouse management system that supports REST API calls. That includes every major WMS on the market. This page explains how the integration works, what it looks like in practice, and how it connects to the specific WMS platforms your operation may already be running.
No proprietary middleware. No custom connectors. If your WMS can make an HTTP call, it can drive pick-to-light.

How the Integration Works
Voodoo Robotics provides a cloud-hosted REST API. Your WMS sends standard HTTP requests to control the pick-to-light devices — turning lights on, displaying pick instructions, showing quantities, colors, and custom messages. The devices respond through the same API, confirming picks and sending event data back to your WMS.
Because it's a standard REST API, the integration works the same way regardless of which WMS you're running. If your system can make an API call — and every modern WMS can — it can drive Voodoo pick-to-light devices.
Standard REST API
JSON over HTTPS. No SDKs, no proprietary protocols, no special middleware required.
Cloud-Hosted
No on-premise servers to install or maintain. The API endpoint is always available and scales automatically.
Bidirectional
Your WMS sends pick instructions out. Device events flow back in real time. Full closed-loop execution.
The REST API Communication Loop
Every pick-to-light interaction follows the same pattern, regardless of WMS. Here's the complete round trip:
WMS sends order data
A new order or picklist in your WMS triggers an API call to Voodoo's cloud platform, specifying which locations need to light up, what to display, and in what color.
Devices illuminate
The cloud platform pushes instructions to the wireless devices. Light modules at the specified SKU locations illuminate with pick quantities, order details, and directional guidance.
Picker executes
The warehouse picker follows the lights, retrieves the correct items, and confirms each pick by pressing the device button or scanning a barcode.
Confirmation flows back
The confirmation triggers an API callback to your WMS, updating inventory levels, order status, and pick completion records in real time.
Next pick activates
The WMS processes the confirmation and sends the next instruction. The loop continues until the order or wave is complete.
Picking Workflows Supported
The same REST API supports every major picking methodology. Your WMS controls the workflow logic; Voodoo handles the visual execution layer.
Single Order Picking
The WMS processes one order at a time, lighting up locations for that order's SKUs. Each confirmation updates the order status before the next pick activates.
Batch Picking
The WMS groups multiple orders with overlapping SKUs into one picklist. Devices use color coding to distinguish which items belong to which order, enabling multi-order picking in a single pass.
Zone Picking
The WMS assigns pickers to specific warehouse zones. API calls activate devices only in the assigned zone, and hand-off between zones is coordinated through the WMS.
Wave Picking
Orders are organized into waves based on shipping schedules, carriers, or priorities. The WMS sequences API calls to process each wave in order.
Put-to-Light Sortation
After batch picking, items are sorted into order-specific totes or slots at a put wall. Devices on the wall illuminate to show the picker where each item goes.
Replenishment
When inventory hits a threshold, the WMS triggers replenishment lights that guide workers to restock specific locations. Confirmation updates the WMS inventory count.
Cycle Counting
The WMS selects locations for cycle counts and lights them sequentially. Workers scan and count, with results flowing back to the WMS for reconciliation.
Quality Control
The WMS activates devices at random or selected locations for QC checks. Inspection results return to the WMS through the same API.

Why Wireless Makes Integration Easier
Traditional pick-to-light systems require hardwired connections between devices, controllers, and on-premise servers — creating a complex infrastructure layer between your WMS and the light modules. Voodoo's wireless architecture eliminates all of that.
No On-Premise Servers
The cloud API eliminates server hardware, maintenance, and the IT overhead of running pick-to-light infrastructure in your facility.
No Wiring
Devices run on AAA batteries for a year or more and communicate via WiFi. Mount them anywhere — shelves, carts, totes, put walls — with magnets or tape.
Minutes to Deploy
Add a device to your network, associate it with a location in the API, and it's live. No electricians, no cabling, no downtime.
Easy to Reconfigure
When your warehouse layout changes, move the devices. No rewiring, no contractor visits. Your API location mappings update instantly.
Works with Excel Too
Don't have a WMS yet? Voodoo Robotics also integrates with Microsoft Excel and Google Sheets. Many customers start with a spreadsheet-driven pilot to prove the value of pick-to-light before committing to a full WMS integration. The same devices and API work either way — you can graduate from Excel to a WMS without changing any hardware. Learn more about how integration works.
