action=setnotificationtimestamp API is not documented anywhere. I just spent a few hours rewriting it only to learn it already exists. I am now very angry.

https://www.mediawiki.org/w/api.php?action=help&modules=setnotificationtimestamp links to https://www.mediawiki.org/wiki/API:SetNotificationTimestamp , which does not exist.

Also, the docs (both on mw.org and in code) should mention something about marking pages/revisions as visited, since that's how it's called in the UI ("notification timestamp" is an internal term and currently a lie).
