Você também pode usá-lo para gerar código automaticamente para clientes que se comunicam com sua API. Por exemplo, aplicativos front-end, móveis ou IoT.

### Faça o deploy da sua aplicação (opcional) { #deploy-your-app-optional }

También podrías usarlo para generar código automáticamente, para clientes que se comuniquen con tu API. Por ejemplo, aplicaciones frontend, móviles o IoT.

### Despliega tu app (opcional) { #deploy-your-app-optional }

Opcionalmente puedes desplegar tu app de FastAPI en <a href="https://fastapicloud.com" class="external-link" target="_blank">FastAPI Cloud</a>, ve y únete a la lista de espera si aún no lo has hecho. 🚀

### Technical details about the JWT "subject" `sub` { #technical-details-about-the-jwt-subject-sub }

The JWT specification says that there's a key `sub`, with the subject of the token.

It's optional to use it, but that's where you would put the user's identification, so we are using it here.

JWT might be used for other things apart from identifying a user and allowing them to perform operations directly on your API.

Вы также можете использовать её для автоматической генерации кода для клиентов, которые взаимодействуют с вашим API. Например, для фронтенд-, мобильных или IoT-приложений.

### Разверните приложение (необязательно) { #deploy-your-app-optional }

При желании вы можете развернуть своё приложение FastAPI в <a href="https://fastapicloud.com" class="external-link" target="_blank">FastAPI Cloud</a>, перейдите и присоединитесь к списку ожидания, если ещё не сделали этого. 🚀
