CMP verification

Verify DataReporter GmbH by country and state

Check the DataReporter GmbH configuration visitors actually receive, the choice it saves, and what your tags do with that choice. Choose a location below for the regional check, routing requirements, and a reusable worksheet.

A saved rejection can still leave a tag running

Example policy: optional analytics must stay off after refusal. Change the evidence for a DataReporter GmbH visitor in Germany and see what you can conclude. These values are teaching fixtures.

02 · SAVED CHOICEOptional analytics: deniedDataReporter GmbH readback after the example refusal.
03 · BROWSER ACTIVITYOptional analytics cookie appearsExample capture window: 10 seconds after the choice. Server-side processing is outside this fixture.

Investigate the mismatch

The saved choice is readable, but observed activity conflicts with the example policy. Trace the affected integration and retest after deployment.

Build your repeatable test plan

Test scope

6 worksheet rows. First load, acceptance, and refusal each use fresh sessions. The worksheet records actual region, selected rule, expected policy, saved state, and observed activity.

Independently verify DataReporter GmbH on https://example.com for a visitor in Germany.
CookieTrail offers a Germany country route (de). Confirm the CMP's selected rule in the evidence before interpreting the result.
Trace the first tag before the banner is clicked. Start a new browser session and compare the first nonessential cookie or request with the time the consent defaults were set. A German banner can appear after a tag has already run.

Run these paths: first load, accept optional categories, reject / opt out. Use fresh isolated sessions for first load, accept, and reject; withdrawal uses its own earlier acceptance. Record the URL, deployed version, actual visitor region, selected CMP rule, expected policy, saved state, cookies, requests, and capture window. Use the installed CMP's documented readback; missing data is inconclusive. Do not equate a TCF applicability flag or a banner language with geography.

Compare saved choices with observed behavior against the team's stated policy. A request alone does not establish a violation; Google advanced Consent Mode may send cookieless requests. Do not assume browser evidence covers server-side tracking. Investigate mismatches in my repository and explain each finding with evidence. After I deploy a fix, repeat the same URL, regional rule, and paths, then compare both evidence sets.

CookieTrail can capture its supported country routes through its workspace/API/MCP. State/province routing, browser preference signals, and withdrawal require separate verified manual or external browser tests; do not claim those are built-in automated paths. This is a technical test, not legal certification.

Country-route capture is available for CookieTrail’s supported locations. Precise state/province routing, withdrawal, and browser preference signals need separate manual or external tests.

Read DataReporter GmbH’s saved state

Check DataReporter GmbH's TCF identity and the site's purpose mapping.

  1. Record the DataReporter GmbH script or plugin version, configuration identifier, and published regional rule. Check the deployed site rather than a dashboard preview.
  2. If this installation enables the IAB Transparency and Consent Framework (TCF), compare its returned cmpId with 426, the ID in Google's inventory. An absent TCF API may simply mean TCF is not enabled.
  3. Map each saved category or purpose to the site's actual tools. Compare those tools' storage and requests before and after the visitor's decision.
Optional TCF identity and purpose snapshot · CMP ID 426

Use this only when TCF is enabled. Run it again after each decision. The CMP ID identifies the platform; it is not an advertising vendor ID. Compare purpose and vendor permissions separately.

(() => {
  if (typeof window.__tcfapi !== "function")
    return { status: "TCF unavailable or disabled" };
  window.__tcfapi("addEventListener", 2, (data, ok) => {
    if (!ok || !data ||
        !["tcloaded", "useractioncomplete"].includes(data.eventStatus))
      return;
    console.log({
      cmpId: data.cmpId,
      expectedCmpId: 426,
      identityMatches: data.cmpId === 426,
      cmpStatus: data.cmpStatus,
      eventStatus: data.eventStatus,
      gdprApplies: data.gdprApplies,
      purposeConsents: data.purpose?.consents,
      purposeLegitimateInterests: data.purpose?.legitimateInterests
    });
    window.__tcfapi("removeEventListener", 2,
      () => {}, data.listenerId);
  });
})()

A TCF applicability flag does not verify geography. Legitimate-interest fields and consent fields have different meanings; rejection does not imply every field becomes false. This uses the documented TCF event API; getTCData is deprecated.

These procedures use documented readbacks or manual saved-state checks. They do not imply that CookieTrail has an automated native adapter for every installation. DataReporter GmbH is identified in Google’s referenced CMP inventory or partner list.
