Cookies
This guide explains the Nosto usage of cookies
Disclaimer: It is the merchant’s responsibility to ensure that all cookie-related features comply with the data-protection laws, regulations, and policies that apply in their specific country and region.
To ensure that the Nosto Plugin and the Nosto Debug Toolbar operate correctly, the following cookies must be accepted:
2c.cid
Visitor-specific identifier used by Nosto for analytics and personalisation. Set only when tracking is allowed (i.e. not in doNotTrack mode).
nosto-integration-allowed
Consent to load Nosto (essential). Replaces the former nosto-integration-track-allow, which is still honoured for shoppers who already consented.
nosto-search-session-params
Stores search-session parameters for more precise recommendations.
nostoCookieFilter
Includes all Search/Category merchandising filters and values
nostoCookieFilterMapping
Includes mapped Search/Category merchandising filters
nosto_preview
Used to preview Search/Category merchandising results without enabling it globally on a live store
nosto-track
Marketing consent: allows Nosto to send customer data and track the visit (no doNotTrack).
1. Cookie-Consent Banner
When a customer visits the store for the first time after the Nosto Plugin has been installed, Shopware displays its cookie-consent banner. The plugin adds two consent options:
A Nosto group - consent to load Nosto on the storefront.
A Nosto Marketing entry under the Marketing group - consent to send customer data and enable full tracking.
Why it matters Nosto loads once the essential consent cookie (
nosto-integration-allowed) is present. If the shopper accepts Nosto but not marketing, Nosto still loads but runs withdoNotTrackenabled - no session identifier (2c.cid) is set and no customer data is sent. Accepting Nosto Marketing enables full tracking.
After accepting Shopware default cookie consent, cookie nosto-search-session-params is created which then allows Nosto script to load as well as other Nosto functionality.
2. Send Customer Data to Nosto
Found under Settings → Plugins → Nosto → Features flags, this setting controls whether customer data (email, name) is sent to Nosto:
Rely on nosto_track cookie (default) — customer data is sent only when the shopper has accepted the marketing (
nosto-track) cookie; otherwise Nosto runs withdoNotTrack.Always send — customer data is always sent.
Never send — customer data is never sent, and
doNotTrackis enabled.
Info Backend synchronisation jobs (new orders, newsletter subscriptions) run server-side with no cookie available, so they send customer data only when this is set to Always send.
3. Nosto Debug Toolbar
The toolbar allows developers to inspect page-level Nosto events, placements, and requests while browsing the storefront.
If you find the page load speeds a little slow, you can enable Nosto script initialization on the page interaction, that means that Nosto will only run after the user interacts with the page (scroll, click etc)
Navigate to Settings → Plugins → Nosto → All Sales Channels.
In General Settings, enable Initialize Nosto Script After First Page Iteration.
4. Treat Nosto as an Essential Cookie
The Treat Nosto as an essential cookie setting (Settings → Plugins → Nosto → Features flags) decides whether Nosto may load without explicit consent. It is enabled by default.
Enabled (default) - Nosto is registered as a technically required cookie and loads for every visitor, running in
doNotTrackmode until marketing consent is given. This matches the behaviour of earlier plugin versions.Disabled - Nosto loads only after the shopper accepts the Nosto cookie group in the banner. If they decline it, Nosto is never loaded and sends no requests.
This may not work with third-party cookie-consent managers - in that case, follow their documentation to allow the Nosto cookies (see section 5)
Backend steps
Go to Settings → Basic Information → Security and Privacy.
Disable Use default cookie notification.
(Only if it was turned off) In Settings → Plugins → Nosto, make sure "Treat Nosto as an essential cookie" is enabled - it is enabled by default.
Optionally hide Shopware's banner entirely: if explicit consent is not legally required in your region, go to Settings → Basic Information → Security and Privacy and disable Use default cookie notification. Combined with the setting enabled above, Nosto cookies are set automatically on first page load and no banner is shown.
5. Third-Party Cookie consent Manager (not Shopware default)
Third-party cookie-consent managers usually override Shopware's default banner. In that case, follow the specific manager's documentation and settings to allow the Nosto cookies.
This also means that if Treat Nosto as an essential cookie is enabled, it can still be blocked by a third-party manager unless configured within its settings.
Cookies that may need to be added explicitly:
