The «Payment solution protocol for merchants» → «Payment form» → «Form for HTTP notifications» section of the Yandex.Kassa documentation states that shopSuccessURL and shopFailURL can have up to 250 characters:

I have got a response from the Yandex.Kassa support:

Правильным значением является ограничение в 250 символов.
В ближайшее время мы поправим информацию на сайте.

So the right value is 250 characters.
