title: Attribution looks wrong
description: Diagnose why a conversion is credited to the wrong channel, or attribution data is missing.

## Symptom

Attribution looks wrong — the wrong channel, campaign, or click gets credit for a conversion, or attribution data appears to be missing entirely for a visitor you know clicked a link.

## Likely causes

1. **`GET /s/{code}` had already expired or was paused before the click (`410`)**, or the click never resolved through Retidal at all.

   ```bash
   curl -s -o /dev/null -w "%{http_code}\n" https://api.retidal.com/s/{code}
   # 410 means the link itself is the problem, not the attribution logic downstream
   ```

2. **The event that should carry `clickIds` was sent without them, or after the attribution window had already closed.**

   Console → Projects → Visitors → (select the visitor) — check the visitor's attribution fields (short link, `utmSource`/`utmMedium`/`utmCampaign`, `clickIds`) for the click in question. The Links page's per-link analytics only shows aggregate click counts and device breakdown, not individual visitors.

3. **The underlying data is older than the 90-day retention window and its source rows have already been purged** — this data cannot be recovered or recomputed, by design.

   Console → Projects → Decision funnel — a data-gap indicator for a date range this old confirms it is outside the 90-day window, not a bug.

## Still stuck

If the click and attribution data are both within the retention window and still look wrong, see [Decisioning not firing](/docs/troubleshooting/decisioning-not-firing) or the [health checklist](/docs/troubleshooting/health-checklist).
