Resolver rules control what happens when someone scans a 2D barcode (QR code) on your product. You can direct scanners to your product page, a promotional landing page, a traceability portal, or different destinations based on time, location, or product batch.
Running a fixed scanning station on a static IP? Publish a DNS LOC record to pin every scan from that IP to your facility’s exact surveyed coordinates — see Pin a Facility’s Location with a DNS LOC Record.

What Is a Resolver Rule

When a consumer or partner scans a GS1 Digital Link barcode on your product, Closient evaluates your resolver rules to determine where to redirect them. Rules are evaluated in priority order — the first matching rule wins.

​
Creating a Rule

Navigate to Resolver > Rules in your Dashboard, or open a specific product and go to its Resolver tab.

​
Basic Setup

1

Choose a scope

Select what the rule applies to:
  • Organization — applies to all your products (catch-all)
  • Brand — applies to all products under a specific brand
  • Product — applies to a single GTIN
  • Batch — applies to a specific production lot
  • Serial — applies to a specific individual item
2

Set the destination

Choose where scanners are sent:
  • Hosted Page — Closient generates a product information page for you automatically
  • Custom URL — redirect to your own page (e.g., your brand website, a landing page, or a traceability portal)
3

Set priority

If you have multiple rules for the same scope, set the order index. Lower numbers = higher priority.

​
Custom URL Fallback

When using a custom URL, configure what happens if your URL goes down: Closient monitors your custom URLs automatically and tracks consecutive failures.

​
Time-Based Rules

You can make rules active only during certain times — useful for seasonal campaigns, business hours, or limited-time promotions. All time criteria are AND-ed — if you set both days of week and time of day, the rule only matches when both are satisfied.
Set your organization’s routing timezone in Settings > Resolver so time-based rules use your local time, not UTC.

​
Rule Priority (Scope Hierarchy)

When multiple rules could match a scan, Closient evaluates from most specific to least specific:
  1. Serial — a rule for this exact serial number
  2. Batch — a rule for this production batch
  3. Product — a rule for this GTIN
  4. Brand — a rule for all products under this brand
  5. Organization — a catch-all for all your products
Within each scope level, rules are evaluated by order index (lowest first).

​
Example

A beverage brand sets up:
  • Organization rule → brand website (catch-all)
  • Product rule for their new energy drink → dedicated landing page
  • Batch rule for recalled lot #2026-Q1 → recall notice page
When someone scans:
  • The recalled batch → recall notice (batch rule wins)
  • The energy drink (non-recalled batch) → landing page (product rule wins)
  • Any other product → brand website (organization rule wins)
You can also scope rules by GS1 link type. When the resolver receives a request for a specific link type, it only considers rules matching that type:

​
Monitoring Rule Health

The Dashboard shows health status for each custom URL rule:
  • Healthy — URL responding normally
  • Degraded — intermittent failures detected
  • Down — consecutive failures, fallback behavior active
You’ll receive notifications when a custom URL starts failing.
