Absolutely useless extension that should be removed from the web store. Downloaded it, tested it out, noticed that it does nothing, so deleted it, only redownloaded it so that i could leave a review. Doesnt work for its intended purpose so do not understand why its even on here. If i could give no stars, trust me, i would.

Quick Guide to Using the CMP Validator The IAB Europe CMP Validator scans web pages to detect and validate embedded Consent Management Platforms (CMPs). It checks for the availability and correct functioning of a TCF-registered CMP that supports the latest updates to the Transparency and Consent Framework (TCF). If no CMP is found, the tool will display “No CMP API found on this webpage.” This may mean that no CMP is implemented on the page, or that a CMP is present but not initiated because the publisher determined the user is not subject to GDPR. If a CMP is present (commonly on publisher sites that display advertising), the validator will test it against the latest TCF policies and specifications to confirm compliance. I hope this helps!

Just not working. Keeps saying "No CMP API found on this webpage. CMP validator cannot operate."

It doesn't work for me. I get the "No CMP API found on this webpage" message on all kind of websites (iabeurope.eu, google.com, onetrust.com...). I've also tried in incognito and same result.

Very very useful extension for anyone dealing with GDPR / Consent management.

In the latest version 2.2.6, we have resolved two key issues: 1. Previously, at the initial CMP state (where CMP is displayed but no user action has been taken), our validator detected the presence of a CMP API but failed to populate any results from TCF API calls. With this update, the CMP validator will correctly populate the summary and API sections with values retrieved from TCF APIs. 2. Since version 2.2.4 (released on December 7, 2023), our CMP validator attempted to load a file from https://vendor-list.consensu.org/v3/archives/vendor-list-vundefined.json in cases where there were errors loading basic CMP data, resulting in a 403 Forbidden error. This issue has been rectified."

Improved extension, which helps you audit TCF compliance from your Consent Management Platform. Further improvements could include (1) adding support for Google ATP vendors (2) providing feedback to publisher/CMP Vendor / IAB Europe on misconfigured CMPs (e.g. loading too late, not firing, etc) to drive compliance. My guess is the tool is used almost exclusively within the digital media industry so later would be useful.
