Конечные точки REST API для назначенных проблем

Сведения о пользователях, которым назначены проблемы и запросы на вытягивание

REST API можно использовать для просмотра, добавления и удаления назначаемого пользователя по проблемам и запросам на вытягивание. Каждый запрос на вытягивание является проблемой, но не каждая проблема является запросом на вытягивание. По этой причине общие действия для обоих функций, например управление назначателями, метками и вехами, предоставляются в конечных точках проблем.
