Criar pedidos via programa??o

Olá comunidade, estou tentando realizar pedidos via programa??o, eu tenho conseguido através da fun??o wc_create_order();

$address = array(
‘first_name’ => get_user_meta( $customer_id, ‘billing_first_name’, true ),
‘last_name’ => get_user_meta( $customer_id, ‘billing_last_name’, true ),
‘company’ => get_user_meta( $customer_id, ‘billing_company’, true ),
‘cnpj’ => get_user_meta( $customer_id, ‘billing_cnpj’, true ),
‘sex’ => get_user_meta( $customer_id, ‘billing_sex’, true ),
‘neighborhood’ => get_user_meta( $customer_id, ‘billing_neighborhood’, true ),
’email’ => get_user_meta( $customer_id, ’email’, true ),
‘phone’ => get_user_meta( $customer_id, ‘billing_phone’, true ),
‘address_1’ => get_user_meta( $customer_id, ‘billing_address_1’, true ),
‘address_2’ => get_user_meta( $customer_id, ‘billing_address_2’, true ),
‘number’ => get_user_meta( $customer_id, ‘billing_number’, true ),
‘city’ => get_user_meta( $customer_id, ‘billing_city’, true ),
‘state’ => get_user_meta( $customer_id, ‘billing_state’, true ),
‘postcode’ => get_user_meta( $customer_id, ‘billing_postcode’, true ),
‘cpf’ => get_user_meta( $customer_id, ‘billing_cpf’),
‘country’ => get_user_meta( $customer_id, ‘billing_country’, true )
);

order = wc_create_order();

Porem n?o cadastra os campos do Brazilian Market

$order->update_meta_data(‘_billing_birthdate’, $billing_birthdate); $order->update_meta_data(‘_billing_cpf’, $billing_cpf);

‘cpf’ => get_user_meta( $customer_id, ‘billing_cpf’),

Acima algumas tentativas sem sucesso.

Alguém já resolveu isso?
