Resolver Rules and Traceability - Why Closient Is Different

What Are Resolver Rules?

Resolver rules are the core of Closient's Digital Link resolution. Each rule defines conditions (scope, time window, locale, link type, product status) and a destination. When a consumer scans a QR code, rules are evaluated from most specific to least specific. The first match wins.

Resolution Hierarchy

Serial Batch / Lot Trade Item Product Brand Organization Closient Global

Rules at the serial level override batch rules, which override trade item rules, and so on. A global fallback rule always ensures every scan reaches a destination.

Use Case 1

Serve the Right Language, Automatically

A single product sold in Canada needs English and French content. With resolver rules, the same QR code printed on every unit routes French-speaking consumers to a French product page and English-speaking consumers to the English page — based on their browser language.

Rule 1 - French Canada

{
  "scope": "TRADE_ITEM",
  "allowed_languages": ["fr"],
  "allowed_countries": ["CA"],
  "destination": "https://example.com/produit/fr-ca",
  "order": 1
}

Rule 2 - English (fallback)

{
  "scope": "TRADE_ITEM",
  "allowed_languages": ["en"],
  "destination": "https://example.com/product/en",
  "order": 2
}

With a basic redirect service, you'd need a separate QR code per language — and a reprint for every new market.

Use Case 2

Route by Time — Promotions, Seasons, Campaigns

Run a holiday promotion that activates on December 1 and expires on January 5 — without touching your packaging. Outside that window, the same QR code routes to the standard product page. Schedule day-of-week or time-of-day rules for weekend specials or shift-specific content.

Rule 1 - Holiday promotion

{
  "scope": "TRADE_ITEM",
  "annual_start_mmdd": "12-01",
  "annual_end_mmdd": "01-05",
  "destination": "https://example.com/holiday-promo",
  "order": 1
}

Rule 2 - Weekend specials

{
  "scope": "TRADE_ITEM",
  "days_of_week": [5, 6],
  "destination": "https://example.com/weekend-deals",
  "order": 2
}

Time criteria include absolute date ranges, recurring annual windows, day-of-week, and time-of-day — all evaluated in the organization's configured timezone.

Use Case 3

Automatic Recall Override — Safety First

When a high-severity recall is issued, Closient's resolver bypasses all normal rules and redirects every scan of the affected product to a recall landing page. This happens instantly — no rule editing, no reprint, no delay.

Recall Issued

A safety issue is reported. The recall is flagged as high-severity in Closient.

Override Activates

The resolver detects the recall before evaluating any rules. All scans are intercepted.

Consumer Protected

Every scan of the affected GTIN, batch, or serial number reaches the recall notice.

  "gtin": "00012345678906",
  "batch": "LOT2025A",
  "matched_scope_type": "RECALL_OVERRIDE",
  "recall_override_applied": true,
  "final_destination_url": "/recalls/urgent-allergy-alert/00012345678906"
}

What This Means vs. QR Redirect Services

Basic redirect services send every scan to one URL. Closient's resolver rules make that one QR code work across languages, markets, campaigns, and safety events.
