This guide is for agents made in the Builder. The widget always uses the published version of the agent, never the draft you are editing.
What you need
- A published agent. To offer voice, the agent needs its voice and transcription configured, the same as for phone calls.
- A payment method saved and credits in your account.
- Access to your website’s code, or to the place where your site builder lets you paste a script.
Set up the widget
1
Open the agent in the Builder
From Agents, open the agent and go to the Channels tab. Click Configure on the Web widget card.
2
Choose where it can be shown
Under Allowed Domains, write your site’s domain without
https://, one per line: yourdomain.com. Use *.yourdomain.com to allow all of its subdomains; it does not include yourdomain.com itself, so write both if you want both. localhost:3000 works for testing on your computer.3
Choose what visitors can do
Turn Type (text chat) and Talk (a call from the browser) on or off, then turn on Show the widget and click Save changes.
4
Paste the code
Copy the code under Code for your website and paste it before
</body> on every page where you want the bubble.How it is protected
The code carries a publishable key (ryvo_pk_...). It is public on purpose: anyone who opens your site can see it, the same way they see the rest of your code. What stops someone from using your agent from another site:
- Allowed domains. The widget only opens inside the domains you wrote. The visitor’s browser enforces this, so another site that copies your code gets an empty frame.
- A human check. Each conversation and each call starts with an invisible check that tells a person from a bot.
- Rate limits per visitor, per agent and per account.
- Your account’s own limits. Balance, simultaneous calls of your plan and the rest of the checks of any conversation still apply.
What it costs
Each widget conversation is billed like a web conversation: text per message and voice per minute, at your plan’s rate. Conversations show up in your history with the Widget channel, next to the rest of your agent’s conversations.Troubleshooting

The domain of the page is not in Allowed Domains. Check that you wrote it exactly as it appears in the address bar, without
https:// and without a path. www.yourdomain.com and yourdomain.com are different domains.The widget says the assistant is not available

The agent is unpublished or paused, the widget is off, or your account ran out of credits. Check the Web widget card in the Channels tab and your balance.
Voice does not start
Voice does not start
The visitor has to allow the microphone. If the Talk mode does not appear, the agent does not have voice and transcription configured in its published version.
