About WorldPay

Payment confirmation callbacks to ecommerce backends

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.

WorldPay user agent

WorldPay identifies itself with this user agent string:

  • WJHRO/1.0 (WorldPay Java HTTP Request Object)

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 WorldPay in robots.txt

We have not confirmed whether WorldPay 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 WorldPay from the whole site

User-agent: WJHRO
Disallow: /

Block WorldPay from some folders

User-agent: WJHRO
Disallow: /private/
Disallow: /search

Allow WorldPay only on some folders

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

Allow WorldPay and block other crawlers

User-agent: WJHRO
Allow: /

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

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

Frequently asked questions

What is WorldPay?

WorldPay is a bot in the webhook senders category, operated by WorldPay. Payment confirmation callbacks to ecommerce backends

Does WorldPay respect robots.txt?

We have not confirmed whether WorldPay follows robots.txt. Add a robots.txt rule, then check your logs to see that it stopped, and block it by user agent if it did not.

How do I block WorldPay?

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

Is robots.txt enough to block WorldPay?

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

Should I block WorldPay?
