Electronic Shelf Labels for Square POS
RetailLume's Square integration has been implemented and verified in Square Sandbox, including merchant OAuth authorization, location-scoped catalog import, automatic webhook price updates, store-level pause controls, and controlled wireless updates to a 2.9" e-paper shelf label.
What Is Verified & Supported
Project Verified- Square OAuth authorization and encrypted credential storage scoped to your selected store location.
- Catalog synchronization for fixed-price Square items and item variations, including location-specific price overrides.
- Signed Square webhook updates that refresh staged shelf prices automatically when a fixed item price changes in Square.
- Store-level dispatch pause control and wireless delivery confirmation verified in a controlled setup with a 2.9" e-paper shelf label.
Current Scope, Limits & What We Confirm
Important Pre-Check- Status: Verified in Square Sandbox and controlled hardware testing; production Square merchant onboarding is confirmed per store during pilot setup.
- Items configured with Variable Pricing in Square are skipped because a shelf label requires a fixed selling price.
- Automatic discount rules or cart-level promotions in Square are not displayed unless reflected in the item variation's fixed selling price.
How Square POS Fits into a RetailLume Shelf-Label Workflow
1. Authorize Your Square Location
Connect your Square account via OAuth and select the specific store location whose prices should drive your shelf labels.
2. Import Fixed-Price Catalog Items & Variations
RetailLume imports your items, variations, SKUs, barcodes, and location-specific prices into an isolated store workspace.
3. Pair Shelf Labels with Store Pause Safety
Map physical e-paper labels to your Square item variations while keeping physical dispatch paused until your floor check is complete.
4. Keep Shelf Prices in Step Automatically
When you update a fixed item price in Square, verified webhooks update RetailLume and queue wireless label updates according to your store settings.
Frequently Asked Questions — Square POS & Electronic Shelf Labels
Read Full Practical FAQ (~100-Item Pilots, Coolers, Batteries & Installation) →Does RetailLume support multiple Square locations?
Yes. Each store in RetailLume maps to a specific Square location and honors location-specific price overrides configured on your Square item variations.
What happens if we want to pause shelf updates during a store reset?
RetailLume includes a store-level pause control. While paused, incoming Square price changes are recorded in your workspace without transmitting changes to the physical shelf labels until you are ready.
How does RetailLume handle variable-priced Square items?
Items set to Variable Pricing in Square (where the cashier types a price at checkout) are automatically skipped during catalog import so shelf labels only display confirmed fixed prices.
