Step 1 — Add the script to your frontend project

Prismic is a headless CMS, so the FastBots script must be added to your frontend application, not in the Prismic dashboard.

If your frontend uses Next.js:

  1. Open your app/layout.js or pages/_document.js file.
  2. Paste your FastBots script code inside the <head> section:

    <script defer src="https://app.fastbots.ai/embed.js" data-bot-id="YOUR-BOT-ID"></script>

Save the file. Deploy your site. If your frontend uses React, Vue, Svelte, Gatsby, or another framework: Open your main layout or global template file (e.g., Layout.jsx, default.vue, app.html, etc.). Paste your FastBots script code just before the closing </head> tag. Save and redeploy your project. Step 2 — Confirm installation Visit your live website and refresh the page — your FastBots chatbot should now appear across your entire site.   Enable and test voice In FastBots, open Deployment → Chat Widget → Conversation Options. Choose Text and Voice or Voice Only, configure your voice settings and select Save Changes.   After installation, open your website or shared chatbot link as a visitor. Start a voice conversation, allow microphone access and check that you can hear a reply. If you enabled text fallback, check Type instead too. Voice tests consume message credits.   See the Chat Widget and Voice guide for the full setup. The setup wizard still creates a text chatbot; voice is enabled afterwards.
