About TwilioProxy

Twilio webhook requests triggered by Twilio when there are incoming SMSes, calls, etc.

Webhook senders call your endpoints to deliver events from payment, messaging and SaaS platforms. Blocking them breaks integrations. Allow them on the webhook paths they need and nowhere else.

TwilioProxy user agent

TwilioProxy identifies itself with this user agent string:

  • TwilioProxy/1.1

Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.

How to block TwilioProxy in robots.txt

We have not confirmed whether TwilioProxy follows robots.txt. Add a rule, then check your logs to see that it stopped. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.

Block TwilioProxy from the whole site

User-agent: TwilioProxy
Disallow: /

Block TwilioProxy from some folders

User-agent: TwilioProxy

Things to know

  • Each host needs its own file. Rules on www.example.com do not apply to shop.example.com.
  • A crawler obeys only the most specific group that names it. Once you add a User-agent: TwilioProxy group, TwilioProxy ignores your User-agent: * rules, so repeat any that should still apply.
  • The user agent name is not case sensitive. We take TwilioProxy from TwilioProxy's user agent; check Twilio, Inc.'s own documentation if it publishes a different robots.txt name.
  • Crawlers cache robots.txt, so changes can take up to a day to apply. Disallow stops crawling but does not remove pages already collected or indexed.

Limits of robots.txt

  1. TwilioProxy may not follow the rule. robots.txt is a request that nothing enforces, and we have not confirmed that TwilioProxy follows it. Check your logs after adding a rule.
  2. The user agent could be fake. robots.txt matches the name a request claims. Anyone can send TwilioProxy's user agent, and a scraper using it is not bound by Twilio, Inc.'s robots.txt policy. Only checking the source network tells a real TwilioProxy from a fake one.

Treat robots.txt as a statement of your policy, and enforce it where requests arrive.
