Overview

SFBX operates as part of Twilio's communication platform, providing real-time messaging, voice, and chat capabilities embedded into websites. Sites use these scripts to power customer support chat, SMS verification, and voice calling features.

What This Script Does

The SFBX/Twilio Client SDK establishes WebSocket connections for real-time audio and messaging between the browser and Twilio's infrastructure. It handles microphone access for voice calls, renders chat interfaces, and manages session tokens for authenticated communication channels. The script sets session cookies to maintain active communication state. No advertising pixels, behavioral tracking, or audience profiling is involved.

Consent & Compliance

Consent category: Functional

SFBX/Twilio scripts provide communication functionality requested by the user (chat, voice, SMS). Under GDPR, these scripts serve a functional purpose and can operate under legitimate interest when the user initiates a communication action. The ePrivacy Directive permits cookies that are strictly necessary for a service explicitly requested by the user. No marketing data collection is involved.

Should You Block This Without Consent?

No. SFBX/Twilio scripts provide functional communication features with no advertising or tracking component. They can load without requiring marketing or analytics consent.

Frequently Asked Questions

Do I need consent to use SFBX on my website?

Conditional. SFBX provides functional communication features such as SMS, voice, and chat widgets. These set session-scoped cookies for feature operation. Consent is required under GDPR if the integration involves third-party data sharing, but not for purely functional session cookies on your own domain.

What data does SFBX collect from website visitors?

SFBX scripts load the Twilio Client SDK for real-time audio and messaging features. The SDK sets session cookies and collects connection metadata such as device capabilities and network quality to establish voice or chat sessions. No advertising or behavioral tracking data is collected.

How does ConsentStack handle SFBX on my site?

ConsentStack detects SFBX scripts and classifies them as functional. If a visitor denies functional cookies, ConsentStack blocks the SFBX SDK from loading, disabling embedded communication widgets. On consent grant, the SDK initializes normally and communication features become available.
