Integrations
Integrations
Third-party tools are easy to paste into app code, but consent makes them part of your privacy runtime. Analytics SDKs, ad pixels, tag managers, and chat widgets can load remote code, store identifiers, send events, and keep running after the first page view.
Info
Put consent-sensitive vendor tools in c15t instead of scattering script tags across your codebase. c15t becomes the place that decides when they can load, when they must stop, and which consent categories your UI needs to show.
Why Manage Tools In c15t
When you install a vendor directly in your app, your consent logic has to chase that vendor everywhere it appears: page layouts, route handlers, event helpers, tag-manager snippets, and cleanup code.
Register the vendor with c15t instead. The integration becomes a declarative
Script that the consent runtime can reason about:
- c15t registers the tool with the runtime and evaluates it against the current consent state;
- c15t automatically adds the tool's consent category to the active categories,
so GDPR-style consent UIs include
measurement,marketing, orfunctionalitywhen an enabled integration needs them; - c15t blocks the script until consent is granted, or loads it with denied defaults when the vendor has its own consent mode;
- c15t handles revocation by unloading the script or calling the vendor's consent API;
- c15t runs vendor setup in the right order, including queue stubs, global functions, data attributes, default page-view events, and consent updates.
That gives your app one consent lifecycle instead of many scattered vendor lifecycles.
Built-In Helpers
c15t ships prebuilt script helpers in
@c15t/scripts for the
third-party tools developers integrate most often. Prefer them over copied
vendor snippets whenever c15t already supports the vendor.
Every helper returns a regular Script object, so it works anywhere the c15t
script loader accepts scripts. You
usually choose the helper, provide the vendor ID, and pass the result to your
provider's scripts option. The vendor page explains anything else that still
matters, such as custom events, region settings, privacy modes, or ecommerce
payloads.
Choose An Integration Style
Most apps mix more than one style. Pick the smallest one that keeps consent behavior obvious.
| Style | Use when |
|---|---|
Built-in helper from @c15t/scripts | The vendor is listed below — start here. |
Plain Script | One-off app code with simple load and callback behavior. |
| Manifest-backed helper | Reusable vendor integration with structured setup phases, queues, stubs, or a vendor consent API. |
| Iframe / renderable integration | Vendor exposes an iframe or React component, not just a script tag. |
Setup is the same shape in every framework: import the helper, call it with vendor options, and pass the result to the consent runtime through your provider's scripts option. See the framework guides for end-to-end snippets — JavaScript, React, Next.js.
Renderable Integrations
Maps and video embeds need a visible component as well as consent-aware loading.
The React and Next.js packages include components that own the placeholder,
vendor loading, and rendered surface. They are imported from the framework
package rather than @c15t/scripts.
Google Maps
Load the Maps JavaScript API once, then create and clean up consent-aware map instances.
YouTube
Keep privacy-enhanced YouTube iframes unmounted until the required consent is granted.
Analytics
Analytics integrations usually require measurement consent. Some vendors can run in a consent-aware or cookieless mode; others should stay fully blocked until measurement consent is granted.
Google Tag (gtag.js)
Send data to Google Analytics 4 and Google Ads with automatic Consent Mode v2 support.
Ahrefs Analytics
Cookieless web analytics from Ahrefs configured with a single project key.
Adobe Analytics
Load an Adobe Data Collection Tags property behind measurement consent.
Amplitude

Clearbit
Visitor and company enrichment gated on marketing consent.
Microsoft Clarity
Session replay and heatmap analytics with queue stubs and consent-state synchronization.
Databuddy

Rybbit Analytics
Load Rybbit with site configuration via data attributes on the script tag.
Fathom Analytics
Lightweight, cookieless analytics configured entirely through script data attributes.
Heap
Autocapture product analytics with the heap.js callback queue gated behind measurement consent.
Mixpanel Analytics
Product analytics with always-on loading and consent toggled via Mixpanel opt-in and opt-out APIs.
Hotjar
Heatmaps, recordings, and feedback tools with Hotjar globals bootstrapped before script load.
Hightouch
Customer data platform events with an htevents queue bootstrap and optional initial page call.
LogRocket
Session replay and monitoring initialized after measurement consent.
Matomo Analytics
Self-hosted or cloud analytics with queue-based tracking and optional consent-mode commands.
PostHog
Open-source product analytics with cookieless tracking that works even without consent.
OneDollarStats
Load website analytics after measurement consent, with no API key required.
Promptwatch
Artificial Intelligence (AI)-focused website analytics loaded with a project-id script attribute.
Pirsch
Privacy-friendly, cookieless analytics loaded with Pirsch's fixed script id and identification code.
RudderStack
Customer data platform events with a v3 rudderanalytics queue bootstrap and required data plane URL.
Segment
Customer data platform with an analytics queue bootstrap and optional initial page call.
Plausible Analytics
Privacy-friendly, cookieless web analytics with extension support and queue-buffered early calls.
Umami Analytics
Open-source, cookieless analytics configured entirely through script data attributes.
Vercel Analytics
Bootstrap Vercel Analytics with a declarative queue and script attributes.
Functional
Functional integrations usually require functionality consent. They add optional user-facing capabilities, such as chat widgets, that should only run after the user allows them.
Crisp
Load Crisp live chat with the standard website ID bootstrap.
Front Chat
Load Front Chat after functionality consent and initialize the widget when its SDK is ready.
Intercom
Bootstrap Intercom settings and load the messenger widget bundle.
Ads & Pixels
Advertising pixels usually require marketing consent. Many of them need startup stubs so events can be queued safely before the remote SDK loads — built-in helpers handle this for you.
Meta Pixel
Track conversions and build audiences for Facebook and Instagram advertising campaigns.
Snapchat Pixel
Measure Snapchat ad performance and build remarketing audiences with a prebuilt pixel helper.
Reddit Pixel
Track conversions and build audiences for Reddit advertising campaigns.
TikTok Pixel
Measure ad performance and build audiences for TikTok advertising campaigns.
LinkedIn Insight Tag
Track conversions and build matched audiences for LinkedIn advertising campaigns.
Microsoft UET
Track conversions and measure performance for Microsoft Advertising.
X (Twitter) Pixel
Measure ad performance and build audiences for advertising campaigns on X (Twitter).
Pinterest Tag
Track conversions and build audiences for Pinterest advertising campaigns.
Tag Managers
Tag managers can load other scripts, so they deserve extra care. Prefer vendor consent modes and denied defaults before any tags are allowed to run.
Build Your Own
If c15t does not ship the vendor you need, drop down a level:
- build a one-off
Scriptdirectly in your app for simple cases, - build a reusable manifest-backed helper for shared or package-level integrations,
- or combine the script loader with iframe gating for visible media and widget integrations.
Build a Custom Integration
Learn when to use a raw Script, when to use a manifest, and how to debug and test custom integrations.
Where To Next
- Read the script loader guide for your framework: JavaScript, React, Next.js.
- Use the Google Maps and YouTube components for built-in renderable integrations.
- See the iframe blocking pattern for other visible embeds such as calendars and social widgets.
- Use
has()to conditionally run app code based on consent state.
