DataGrail Consent
Connect DataGrail Consent with Webflow to manage cookie consent and stay compliant with GDPR, CCPA, and other privacy regulations.
How to integrate DataGrail Consent with Webflow
Webflow doesn't include built-in consent management, so sites with EU or California visitors need a third-party tool to handle privacy compliance. DataGrail Consent deploys consent banners that adapt to visitor location and applicable privacy regulations, and controls whether scripts fire based on user consent.
You can connect DataGrail Consent to Webflow through the official Webflow marketplace app for the fastest setup, through Google Tag Manager for automated tag control, through direct script embedding for specific use cases, or through the DataGrail API v2 for custom consent workflows that sync with Webflow CMS data.
Use the DataGrail Consent app
The DataGrail Consent app is available through Webflow's official app marketplace and provides a no-code integration path. Once installed, you can configure consent banners, set location-based policies, and manage Webflow Analyze and Optimize tracking directly from the DataGrail dashboard. The app includes a 30-day free trial.
Note that the integration relies on Google Tag Manager (GTM) for consent enforcement and tracker management, even though the app setup itself requires no custom code.
After installation, authenticate your Webflow account in the DataGrail dashboard, select which sites to connect, and link your Google Tag Manager container. The app publishes consent configuration through Google Tag Manager, so you'll need a published GTM container on your Webflow site before the integration works.
Google Tag Manager integration
GTM integration lets you control tracking scripts based on consent state. DataGrail connects to your GTM container, classifies existing tags by consent category, and manages script firing based on user consent preferences without requiring code changes after initial setup. This approach works best when you have multiple analytics or marketing scripts that need consent-based control. DataGrail's January 2026 update also introduced one-click plugin installation for Webflow, so you don't need to configure GTM manually.
According to the DataGrail Webflow Integration Guide, all configuration happens through DataGrail's interface with automatic updates to your GTM container, which then deploys changes to your Webflow site.
- Connect GTM to DataGrail: Authenticate your GTM account and select the container installed on your Webflow site
- Classify tags into consent categories: Assign tags to Analytics, Marketing, and Functional categories to control which scripts require consent
- Configure consent policies: Set geolocation-based rules, opt-in or opt-out defaults, and Global Privacy Control (GPC) signal handling
- Publish updates: Use DataGrail's Review & Update button to deploy changes within minutes
When publishing changes through DataGrail's "Review & Update" feature, the system creates two GTM tags. A Consent Banner tag manages user interaction with the consent interface, and a DataGrail Webflow Plugin tag controls Webflow Analyze and Optimize tracking based on user consent preferences.
Adding GTM to Webflow
If GTM isn't already on your Webflow site, you have two options for adding DataGrail Consent. For the simplest no-code approach, install the DataGrail Consent app directly from the Webflow Marketplace. Alternatively, you can add GTM through Site Settings > Custom Code, paste the GTM container code in the Head Code section, and publish your site. GTM must be live before the DataGrail integration will work.
Direct script embedding
For sites that don't use GTM or need specific control over script loading order, you can embed the DataGrail consent script directly in Webflow. According to the embedded deployment guide, place the script at the top of your site's <head> section to make sure consent checks run before other tracking scripts.
- Site-wide installation: Go to Site Settings > Custom Code and paste the consent script in Head Code
- Page-specific installation: Open Page Settings for individual pages and add the script in the Custom Code section
- Code Embed element installation: Drag a Code Embed element onto your page and paste the script for placement anywhere in the page structure
The script format requires your DataGrail customer ID and container ID:
<script type="text/javascript" src="https://api.consentjs.datagrail.io/[CUSTOMER_ID]/[CONTAINER_ID]/consent-loader.js"></script>Direct embedding requires manual updates when you change consent settings, unlike the GTM approach which automatically syncs changes.
Build with Webflow and DataGrail API
For custom consent workflows like syncing consent records with Webflow CMS, processing privacy requests, or building custom preference centers, the DataGrail API provides programmatic access to consent data.
The DataGrail API v2 uses RESTful architecture with Bearer token authentication. All requests require HTTPS and an API key created in DataGrail platform settings. Store API keys server-side or in environment variables rather than exposing them in client-side code.
- Create opt-out requests: Submit consent preferences from Webflow forms with
POST /api/v2/opt_outs - Update existing consent records: Modify user preferences with
PUT /api/v2/opt_outs/:uuid - Query consent status: Check user consent state with
GET /api/v2/opt_outs - Retrieve privacy requests: Handle data access or deletion requests with
GET /api/v2/privacy_requests
DataGrail's API requires direct REST API calls. There are no pre-built JavaScript SDKs or client libraries.
Syncing consent with Webflow Browser APIs
Webflow provides client-side JavaScript APIs for controlling Webflow Analyze and Optimize tracking. Use these methods to sync DataGrail consent state with Webflow's native analytics:
// Check if user has opted out of tracking
Webflow.analytics.getIsOptedOut();
// Allow Webflow's analytics tracking based on user consent
Webflow.allowUserTracking();
// Withdraw consent for Webflow analytics
Webflow.denyUserTracking();
According to the Webflow help documentation on managing site tracking consent, the DataGrail integration controls Webflow's analytics features through browser APIs. Other tracking scripts must be managed through GTM or the DataGrail API.
Processing privacy requests with webhooks
DataGrail's webhook system sends real-time notifications for privacy requests including Access, Deletion, and Opt-Out events. Configure webhook endpoints to receive notifications when users submit privacy requests, then use the the Webflow CMS API to update or delete corresponding records.
Webhooks require HMAC-SHA256 signature verification and a callback POST response to confirm request processing.
What you can build
Integrating DataGrail Consent with Webflow lets you build privacy-compliant websites that respect user consent, while keeping marketing functionality intact.

- Enterprise brand portfolios: Manage consent policies across multiple Webflow sites from a single DataGrail dashboard, with customizable banner appearance and behavior per brand and jurisdiction
Frequently asked questions
No. Webflow does not provide a built-in consent management system or consent UI. Webflow offers developer APIs for checking and managing user consent status, but you need a third-party consent management platform like DataGrail to handle banner display, cookie blocking, and regulatory compliance.
You need a paid Webflow plan that supports custom code, a published Google Tag Manager (GTM) container on your Webflow site, and a DataGrail Consent account. GTM is required before the integration will function. The consent management system uses GTM to control script firing based on user consent.
Open your browser's developer tools and check the Network tab to confirm the DataGrail consent script loads before other tracking scripts. Visit your published site from different locations (or use a VPN) to verify the consent banner appears with the correct regional settings. After making consent choices, check that tracking scripts in Google Tag Manager fire or block according to your selections. The DataGrail dashboard displays consent events in real-time, so you can verify that user choices are recorded correctly. For Webflow Analyze and Optimize, call
Webflow.analytics.getIsOptedOut()in the browser console to confirm the tracking state matches user consent.
