# s58_a006

Telnyx AI Assistant widget error 'Failed to initialize / Make sure that the Support Unauthenticated Web Calls option is enabled' = the supports_unauthenticated_web_calls field is NOT set under telephony_settings. Fix: raw PATCH to https://api.telnyx.com/v2/ai/assistants/{id} with body {"telephony_settings": {"supports_unauthenticated_web_calls": true}}. The Telnyx Python SDK update() method does NOT expose this field — must use httpx raw PATCH. This is UNDER telephony_settings, NOT widget_settings.
