Integrating the ElevenLabs Conversational AI widget into a Wix website involves a series of steps that require a Wix Premium plan due to the necessity of embedding custom JavaScript. Users must first prepare the widget by setting up a conversational agent in their ElevenLabs account and copying the provided JavaScript embed code. With Wix's Dev Mode enabled, the code is added via the Custom Code settings in the Wix Editor. Common issues, such as widget disconnection or JavaScript errors, can often be resolved by ensuring proper Allowlist configurations and by checking that the JavaScript is correctly embedded. The guide also emphasizes the importance of testing the widget across different browsers and ensuring mobile responsiveness. For users encountering persistent issues, ElevenLabs offers support to assist in troubleshooting.
