New to InstantSchema? Read the [Introduction](/) first for how it works and which integration method fits your site. ## 1. Get your Project ID Open your [InstantSchema dashboard](https://app.instantschema.com), select your project, and copy the **Project ID** from the integration panel. ## 2. Add the script tag Paste this into the `` of every page on your site: ```html theme={null} ``` That's it. The loader fetches the right schemas for each page URL and injects them automatically. ## 3. Verify Return to your dashboard. The integration panel polls automatically — it will show **Integration active** once the script is detected on your site (usually within 8 seconds of the page loading). *** ## Other integration methods The CDN script injects schemas via JavaScript. If you need schemas in raw HTML (for maximum SEO fidelity), use a server-side method instead: * [Next.js SDK](/integrations/nextjs) — `` in your root layout * [Astro](/integrations/astro) — `fetchSchemas()` in frontmatter * [Nuxt / Vue SSR](/integrations/nuxt) — `useInstantSchema()` composable * [GTM](/integrations/gtm) — paste the CDN tag as a Custom HTML tag * [Custom API](/integrations/api) — call the REST endpoint directly from your server See [Integrations → Overview](/integrations/overview) for a comparison.
