HTTPS required for Twilio Functions and Assets webhooks starting September 24, 2026
Starting September 24, 2026, we're requiring HTTPS for all traffic to Functions and Assets, which means customers need to update any webhook or callback subscriptions for these URLs to use https:// instead of http://. After September 24, 2026, any HTTP requests will receive a 301 redirect response and disrupt customers’ Functions.
This upgrade gives your applications encrypted connections by default, protecting customer data every time their code runs.
What you need to do to keep your Functions running
Update any webhook or callback subscriptions for these URLs in your setup to use https:// instead of http:// before September 24, 2026. Once you've made the switch, test your endpoints to make sure everything's working smoothly.
