About GoogleAPI

APIs-Google is the user agent used by Google APIs to deliver push notification messages. Application developers can request these notifications to avoid the need for continually polling Google's servers to find out if the resources they are interested in have changed. To make sure nobody abuses this service, Google requires developers to prove that they own the domain before allowing them to register a URL with a domain as the location where they want to receive messages.

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.

GoogleAPI user agent

GoogleAPI identifies itself with this user agent string:

  • APIs-Google (+https://developers.google.com/webmasters/APIs-Google.html)

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 GoogleAPI in robots.txt

We have not confirmed whether GoogleAPI 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 GoogleAPI from the whole site

User-agent: APIs-Google
Disallow: /

Block GoogleAPI from some folders

User-agent: APIs-Google
Disallow: /private/
Disallow: /search

Allow GoogleAPI only on some folders

User-agent: APIs-Google
Allow: /blog/
Disallow: /

Allow GoogleAPI and block other crawlers

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

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

Who should care about GoogleAPI

Publishers

Allow GoogleAPI if it is a service you use, and keep its visits out of page views and ad requests either way.

Transfon Security for publishers

Media buyers and advertisers

GoogleAPI is not a person. Exclude it from campaign and conversion data so reports reflect real visitors.

Transfon Security for advertisers

E-commerce

Allow GoogleAPI only if it works for your store, and keep it away from cart and checkout.

Transfon Security for e-commerce

SaaS and APIs

If GoogleAPI is a service you use, allow it on the endpoints it needs and block it elsewhere.

Transfon Security for SaaS and APIs

Block GoogleAPI with Transfon Security

robots.txt is a request, not an enforcement. Transfon Security shows GoogleAPI by name in the Top Bots report, so you can see how often it visits and which pages it reads. Block or allow it with a User Agent rule, or slow it down with a rate limit decision rule.

Transfon Security

Control GoogleAPI on your site

  • See every GoogleAPI visit and the pages it reads
  • Spot bots that fake trusted crawler names
  • Block, allow or rate limit GoogleAPI with one rule
  • Works with or without robots.txt support

Frequently asked questions

What is GoogleAPI?

To make sure nobody abuses this service, Google requires developers to prove that they own the domain before allowing them to register a URL with a domain as the location where they want to receive messages.

Does GoogleAPI respect robots.txt?

We have not confirmed whether GoogleAPI 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 GoogleAPI?

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

Is robots.txt enough to block GoogleAPI?

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

Should I block GoogleAPI?

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.
