Выполнение запроса POST для https://api.twitter.com/1.1/oauth2/token приводит к тому, что запрос, по-видимому, обрабатывается как запрос GET и переходит к 404. Этот запрос работает от Postman, поэтому я предполагаю, что с моим синтаксисом что-то не так?
curl
-X POST https://api.twitter.com/1.1/oauth2/token
-H "Authorization: <omitted>"
-H "Content-type: application/x-www-form-urlencoded"
-F "grant_type=client_credentials"
Результатом является страница Twitter 404:
