Why Retail Kiosks Usually Fail

Most vendors build “Monolithic Apps.” This means the whole system is one big, fragile block. If the internet blips, the app dies. If the manufacturer changes a price, the kiosk shows the wrong data. These are gadgets, not infrastructure.

Why Wonder Wins: Modular Architecture

We separated the hardware from the data and the checkout. This makes your system stable and fast.

  • The System Stays Up: Our native apps give you hardware-level control. Your kiosks and tablets work even when store Wi-Fi goes down.
  • The Data Stays Clean: Our agnostic data model turns thousands of messy spreadsheets into one machine-readable standard.
  • The Revenue Stays Protected: Financing and payments are built into the core API, not bolted on as an afterthought.

"Scenes" Endpoint for Visual Commerce

The “Scenes” API endpoint lets you query lifestyle imagery with all associated products (and variants). It even includes x,y coordinates to develop visual commerce experiences such as product ‘hot spots’ (the way we use them in our kiosk app).

Your Modular Building Blocks

Assemble your own retail stack using our endpoints:

Catalog Service

Query vectorized product data and "Scenes" for visual commerce. With detailed variant (options) data you can create a smoother shopping experience.

Our Commerce API includes product variants (or options) such as color, configuration, size, and many more.

Real-Time Inventory Endpoint

Get current available quantities, future available quantities, future availability dates, locations, and location types can be queried in real-time, for both manufacturer and retailer inventory. Build out ‘in-stock’ catalogs for websites and marketplace feeds using the Inventory Endpoint.

Transaction Service (WonderPay)

Enable distributed checkout by converting any kiosk interaction into a secure, SMS-based transaction link sent to the shopper's device.

Query the Order Management API to track the lifecycle of "out-of-store" sales, from link generation to final capture.

The service automatically handles dynamic tax calculations based on shipping destination and manages PCI-compliant payment processing across all major card networks and digital wallets

2 Powerful Endpoints for Hot Leads

In-store guests that share specific products or entire carts via text message or email are valuable leads.

Query both ‘analytics’ endpoints for important lead data so you can track them online or bring them back to your store – both online and offline.
