Node Js e HTTP - Aula 02 / Atividade 01. Problema ao fazer um comando POST no CMD com JSON junto.

Olá, tudo bem ? Estou tendo dificuldades ao fazer um comando POST no CMD, junto com um código JSON. O comando é feito pelo CURL, e suas sintaxe é a seguinte:

curl http://localhost:3000/pagamentos/pagamento -X POST -v -H "Content-type: application/json" -d ' { "forma de pagamento": "payfast",  "valor": 10.98,  "moeda": "BRL", "descricao": "criando um pagamento"} '  

Para o JSON ficar mais fácil de visualizar, colocarei o código dele também, o mesmo está aqui: `

{
    "forma de pagamento":"payfast",
    "valor":10.98,
    "moeda":"BRL",
    "descricao":"criando um pagamento"
}

Mas o CMD mostra uma mensagem de erro de sintaxe, mas fiz exatamente como o professor do curso disse. O erro que o CMD mostra é o seguinte:

Note: Unnecessary use of -X or --request, POST is already inferred.

Quando executo o comando sem o código JSON, não aparece nenhum erro. Caso alguém saiba como resolver, agradeço. Abraços !
