## SSE mit POST { #sse-with-post }

SSE funktioniert mit **jedem HTTP-Method**, nicht nur mit `GET`.

Das ist nützlich für Protokolle wie [MCP](https://modelcontextprotocol.io), die SSE über `POST` streamen:

У **FastAPI**, використовуючи OpenAPI, ви можете визначити назви цих вебхуків, типи HTTP-операцій, які ваш застосунок може надсилати (наприклад, `POST`, `PUT` тощо), і **тіла** запитів, які ваш застосунок надсилатиме.
