Why don't you receive http notifications from Yoomoney on Laravel?

Question

YuMoney

Hello. I connect payment to the site through Yoomoney (Yandex.Money). On a site written in pure PHP, there are no problems, notifications come and are processed by the handler page. But on a site made on Laravel 8, notifications simply do not come. I checked all the settings in Yandex, in Laravel I added the handler page to the CSRF protection exclusions. What could be the problem?

Answer 1
