The Price Change Trigger
Complete Price Data your Flow Automation Needs
Previous and current price
The price delta is essential for automation logic. Without it, you cannot calculate the discount percentage or determine whether a price move qualifies for downstream actions like collection membership or campaign triggers.
Compare-at price
Enables Flow to calculate the true discount percentage against the list price, not just the absolute change. This is essential for PLP filter logic and ensures campaign messaging reflects actual discounts.
Derived values in the trigger itself
Change amount, change percentage, discount percentage, and direction of change are computed once within the trigger and are available to every downstream action in your Flow automation.
Real-time detection with audit logs
Triggers fire immediately when prices update, not on nightly schedules. Every price change is logged with timestamps and values for audit trails, compliance, and troubleshooting.
How does Netra Price Signal work?
From Price Updates to Automated Responses
Install, set your threshold once, and let Flow automations take over. Every change is logged and traceable.
Install and connect Shopify Flow
Install Netra: PriceSignal from the Shopify App Store. The app registers as a trigger source inside Shopify Flow, ready to use in any workflow.
Define your monitoring scope
Choose what to watch - a single product, a collection, or your entire catalogue. Scope determines which variant prices the app considers.
Set your threshold
Decide the minimum change that counts - a percentage move up or down. Sub-threshold changes are logged but don't trigger a workflow, keeping your Flow runs focused on real pricing decisions.
Let Price Signal trigger flow automatically
Branch on discount %, change amount, or any derived value. Update metafields, add to collections, tag products, send campaigns - everything downstream of one trigger.
The Existing Gap
Shopify Flow can't react to price changes
Price-change automation lacks a real-time trigger
Most e-commerce platforms have no native trigger for price changes. This means pricing-driven automations - collection updates, discount metafield changes, campaign coordination - still rely on manual updates, scheduled jobs, or custom integrations.
Historical price data isn't available to automations
Automating discount tags, PLP filter updates, and pricing campaigns all require knowledge of the previous price. Most platforms don't provide this context natively, forcing teams to source it from external systems or track it manually.
At scale, filtering signal from noise is essential
ERP syncs, bulk editors, currency rounding, and supplier feeds create constant micro-price changes. Without threshold-based filtering, large catalogues generate thousands of unnecessary automation runs daily, drowning meaningful pricing changes in noise.
Real Merchandising and Marketing Workflows

Discount-bracket metafields for PLP filters
Price changes trigger Flow to compute discount percentage from current versus compare-at price, write the bracket into a product metafield, and sync with Search & Discovery. PLP facets stay accurate within seconds, eliminating manual maintenance.
Automated collection membership
Add products to Sale, Clearance, or price-band collections automatically when price thresholds are crossed. Equally important: remove products when prices return to normal, preventing stale collections after promotions end.
Automated product tags and badges
Apply and remove on-sale, price-drop, and deep-discount tags automatically based on price movements. These tags power theme badges, upsell automation, segmentation logic, and reporting — all driven by a single price-change trigger.
Marketing and compliance
Automated price-drop campaigns
Route price-change events directly to Klaviyo, WebEngage, MoEngage, or your ESP to launch campaigns automatically. Notify wishlist subscribers, trigger abandoned-cart recovery for users who viewed at the higher price, and coordinate messaging in real time.
MAP and marketplace price compliance
Flag variant prices that breach MAP minimums or where selling price exceeds compare-at. For D2C and marketplace brands, trigger feed refreshes to keep Google Shopping, Meta Ads, and marketplace listings aligned with current pricing.
Real-time pricing alerts
Alert pricing and finance teams via Slack or email when variant prices move outside defined ranges. Catch critical errors — misplaced decimals from ERP syncs, prices below cost threshold — within minutes instead of at end-of-day reconciliation.
Automate pricing workflows in Shopify Flow
Trigger collection updates, discount-bracket metafield changes, product tags, marketing campaigns, and compliance checks - all from a single, real-time price-change trigger.
