Integrate NexaGuard CMP with Shopify

Last updated: March 30, 2026
This guide covers the public integration flow for the NexaGuard CMP Shopify app.
Release alignment: production app version nexaguard-cmp-16 (released March 30, 2026).

1. Overview#

After installation and App Embed activation, NexaGuard CMP:
loads the NexaGuard web loader on storefront pages
shows consent UI based on region/configuration
emits TCF/GPP and Google Consent Mode signals
syncs consent categories with Shopify Customer Privacy API

2. Requirements#

Shopify Online Store 2.0+
admin access to theme customization
valid NexaGuard Settings ID

3. Install and Enable#

1.
Install NexaGuard CMP from Shopify App Store.
2.
Go to Online Store -> Themes -> Customize.
3.
Open App embeds.
4.
Enable NexaGuard CMP.
5.
Set your Settings ID in the embed settings.
6.
Save.
Optional advanced path:
if shop.metafields.nexaguard.settings_id exists, it is used automatically

4. Verification#

Storefront loader check#

Open storefront and confirm loader script is present:
Confirm loader network request:

Consent Mode check#

TCF API check#

Shopify Customer Privacy API sync check#

Expected result:
CMP actions update Shopify consent categories (analytics, marketing, preferences, sale_of_data) according to user choice.

5. Debug Mode#

Use URL flags on storefront:
?nxg_debug=1 for console diagnostics
?nxg_debug_ui=1 for the on-screen debug overlay

6. Duplicate Injection Warning#

Use one integration path at a time:
App Embed (recommended), or
manual <script id="nexaguard-cmp" ...> embed
Do not run both together.

7. Compliance Notes#

NexaGuard CMP Shopify integration supports:
GDPR / ePrivacy
IAB TCF v2.3 flows
Google Consent Mode v2 signaling
Shopify Customer Privacy API category synchronization

8. Webhook Topology (Operational)#

NexaGuard manages Shopify app webhooks and privacy compliance webhooks in the managed NexaGuard runtime:
app/uninstalled -> https://api.nexaguard.io/shopify/v2/app/uninstalled
app/scopes_update -> https://api.nexaguard.io/shopify/v2/app/scopes_update
customers/data_request, customers/redact, shop/redact -> https://api.nexaguard.io/shopify/v2/compliance
Merchants do not need to configure webhook endpoints manually.
