Estou recebendo um erro de assinatura inválida no woocommerce rest api. Também estou usando o script oauth 1.0a do ddohttps://github.com/ddo/oauth-1.0a. Eu gerei as chaves da API duas vezes. Também foi removido o parâmetro version dentro do script de oauth, conforme solicitado na documentação da API do restante do woocommercehttp://woothemes.github.io/woocommerce-rest-api-docs/
