OneTrust integration

What OneTrust is

OneTrust is a privacy management platform that provides consent management, cookie scanning, data mapping, and compliance documentation tooling for GDPR, CCPA, and ePrivacy requirements. For e-commerce merchants processing EU customer data, it is a common choice for implementing a consent banner that controls the firing of marketing and analytics tags.

How we integrate OneTrust with Shopify

OneTrust integrates with Shopify through a script tag added to the store's theme, deploying the consent banner on the storefront. Ecom Majesty's work covers configuring OneTrust's cookie categories to align with the store's tag stack (analytics, marketing, personalisation), wiring the consent signal to Shopify's Customer Privacy API and Google Consent Mode v2, and ensuring that downstream tools (GA4, Klaviyo, Meta Pixel) only fire when the appropriate consent has been granted. On headless builds, Ecom Majesty wires OneTrust's JavaScript callbacks into the custom event layer rather than relying on the standard Shopify theme integration.

What the work involves

• OneTrust consent banner deployed via a theme script tag.
• Cookie categories aligned to the store's tag stack — analytics, marketing, personalisation.
• Consent wired to Shopify's Customer Privacy API and Google Consent Mode v2.
• Downstream tools (GA4, Klaviyo, Meta Pixel) gated to fire only on granted consent; callbacks wired into the custom event layer for headless.
