HubSpot Cookie Banner Not Sending Consent to Google Tag Manager on WordPress

[Kec415]

Hi all, 

I’m looking for help or confirmation from anyone who has successfully integrated HubSpot’s new cookie consent tools with Google Tag Manager (GTM) and GA4 — specifically on WordPress sites.

Here's my setup:

- Main website is built on WordPress

- Subdomains for blog and landing pages (`blog.`, `info.`) are on HubSpot CMS

- I’m using HubSpot’s new consent management features across all domains

- Google Tag Manager and Google Analytics 4 are integrated

- GTM config tag is set to fire on Consent Initialization

- Consent banner visibly shows upon WordPress and works from the user’s perspective

The issue:

Even though the banner shows on WordPress, it seems like no consent signal is actually passed to GTM/GA4. Specifically:

- My GA4 event tags fire in GTM Preview Mode

- But no events appear in GA4 DebugView

- I confirmed that "debug_mode: true" is set on my GA4 config tag

- I ran this in the browser console after clicking “Accept” on the banner:

  js
  dataLayer.filter(d => d.event && d.event.includes('consent'))

  …and got an empty array `[]`, which suggests no `consent_update` or `gtag('consent')` event is being pushed into the dataLayer.

My question:

Has anyone successfully gotten HubSpot’s cookie banner to send consent updates to Google Tag Manager on a WordPress site (not just HubSpot CMS pages)?
