Is there an API for websites to disable ad block plus themselves?

I am using the Ad Block Plus extension in Chrome 115 and something caught my attention from a developer's perspective.

On https://satellites.pro/ I got a popup to disable the Ad Block to support the website, which is fine.

I click the button and the Ad blocker get's disabled directly (I did not have to navigate to the Ad blocker and disable it manually).

How is this working from a technical perspective? Couldn't a website trigger this automatically and just disable the ad blocker without asking me? Is this using some Ad Block Plus API?

Entering the website the first time - Remark: "Anzeigen zulassen" is German and says "Accept ads".

Popup to disable adds, ABP is on

After clicking the button (1)

Website reloaded after clicking the button, ABP is off

Solution

  • I found this in the Javascript code of the website:

    c.initCustomEvent("domain_allowlisting_request", !0, !0, b);

    Which lead me to https://gitlab.com/eyeo/adblockplus/abc/webext-sdk/-/merge_requests/298

    So, yes, there seems to be an API for websites to unblock themselves.

    There is more concept in https://gitlab.com/eyeo/adblockplus/abc/webext-sdk/-/issues/171 and it looks like this should only work for "trusted sites".
