Any chance we could get an update on this? We're trying to finish out our integration and creating products is a big roadblock.

I am also running into this issue when attempting to POST a new product. Are there any updates on this issue?

In case you're still having trouble ... getting rid of any square brackets + specifying a attribute_set_id seems to work:

{
    "product": {
        "attribute_set_id": 4,
        "type_id": "simple",
        "sku": "B201-SKU",
        "name": "B201",
        "price": 25,
        "status": 1,
        "custom_attributes": {
            "description": "Heavy Duty Brake Cables",
            "meta_description": "Some describing text w00t"
        }
    }
}
