About WorldlineBot

The Worldline Bot is associated with Worldline, a payment and transactional services company. It handles notifications and callbacks related to payment processing.

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.

WorldlineBot user agent

WorldlineBot identifies itself with this user agent string:

  • Mozilla/3.0 (compatible; Indy Library)

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 WorldlineBot in robots.txt

We have not confirmed whether WorldlineBot 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 WorldlineBot from the whole site

User-agent: Indy
Disallow: /

Block WorldlineBot from some folders

User-agent: Indy
Disallow: /private/

Allow WorldlineBot only on some folders

User-agent: Indy
Allow: /blog/
Disallow: /

User-agent: *
Disallow: /

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: Indy group, WorldlineBot ignores your User-agent: * rules, so repeat any that should still apply.
  • The user agent name is not case sensitive. We take Indy from WorldlineBot's user agent; check Worldline'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. WorldlineBot may not follow the rule. robots.txt is a request that nothing enforces, and we have not confirmed that WorldlineBot 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 WorldlineBot's user agent, and a scraper using it is not bound by Worldline's robots.txt policy. Only checking the source network tells a real WorldlineBot from a fake one.

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

How do I block WorldlineBot?

Add "User-agent: Indy" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "Indy Library" at your WAF. In Transfon Security that is one User Agent block rule.

Is robots.txt enough to block WorldlineBot?

No. robots.txt is voluntary, so WorldlineBot may not follow it, and anyone can send WorldlineBot's user agent, so a fake WorldlineBot ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
