Install the SDK

Pick the option that matches your project.

You have	Use
A site made in Webflow, Framer, Shopify, Wix, Squarespace or WordPress, and you don't write code	Website builders
A plain HTML site, or no build step	Script tag
A JavaScript project with a bundler	npm package
React, Next.js, Vue, Nuxt, Angular, Svelte, Solid, Astro	Frameworks

All options need two values from your dashboard and your deployment:

• Public key: Settings → Developers. It starts with pk_.
• API URL: https://api.justonecx.com

The SDK has no runtime dependencies. The script bundle is small and loads without blocking your page.

TIP

After you install, add your site to Settings → Developers → Domains & CORS. See Allowed origins.
