What Twilio Proxy does
Twilio webhooks are user-defined HTTP callbacks: when an event occurs, such as an incoming SMS message, an incoming phone call, or a voice-call recording becoming available for download, Twilio makes an HTTP POST or GET request to the URL configured for that webhook. The request includes details of the event, such as the incoming phone number or the body of an incoming message.
How to identify Twilio Proxy
Temso identifies Twilio Proxytraffic by matching the request's User-Agent header against this pattern. User-agent strings can be spoofed, so treat a match as an indication, not proof.

What is Twilio Proxy?
Twilio Proxy handles communications between end-users and applications via Twilio. The linked documentation covers Twilio webhooks, user-defined HTTP callbacks in which Twilio makes an HTTP POST or GET request with event details to a configured URL when an event such as an incoming SMS message or phone call occurs.
Can I block Twilio Proxy with robots.txt?
No. These are webhook callbacks that Twilio sends only to URLs a Twilio account holder configured, not crawler requests, so robots.txt does not apply. To stop the requests, change or remove the webhook URL in the Twilio configuration that points at your site.
About Operational Bots
Monitoring, security scanning, link previews, webhooks, and feed fetchers: the utility traffic that keeps integrations and shared links working.
Most of this traffic is service-critical or user-triggered. Webhooks and previews don't follow robots.txt, and blocking them tends to break things you rely on.
