Create a product

Someone knows the end point to create a product?

The operation failed with an error. [400] Bad Request Request validation failed 🥲

This is my request

[
    {
        "sku": "12345SKU",
        "description": "Descripción detallada del producto",
        "price": 199.99,
        "group": "Grupo al que pertenece el producto",
        "external_id": "IDexterno12345"
    }
]
