Webservice Orders

[Zangetsu]

Buenos días,

estoy intentando crear pedidos por webservice. El cliente, transportista y direcciones son siempre las mismas.

Primero creo por webservice el carrito

<?xml version="1.0" encoding="UTF-8"?>
<prestashop xmlns:xlink="http://www.w3.org/1999/xlink">
<cart>
    <id></id>
    <id_address_delivery>4</id_address_delivery>
    <id_address_invoice>4</id_address_invoice>
    <id_currency>1</id_currency>
    <id_customer>1</id_customer>
    <id_guest>1</id_guest>
    <id_lang>1</id_lang>
    <id_shop_group>1</id_shop_group>
    <id_shop>1</id_shop>
    <id_carrier>2</id_carrier>
    <recyclable>0</recyclable>
    <gift>0</gift>
    <gift_message></gift_message>
    <mobile_theme>0</mobile_theme>
    <delivery_option></delivery_option>
    <secure_key></secure_key>
    <allow_seperated_package>0</allow_seperated_package>
    <date_add>2018-02-13 10:30:46</date_add>
    <date_upd>2018-02-13 10:30:46</date_upd>
<associations>
</associations>
</cart>
</prestashop> 

 

Y el id que me genera el carrito anterior se lo paso al pedido

 

<?xml version="1.0" encoding="UTF-8"?>
<prestashop xmlns:xlink="http://www.w3.org/1999/xlink">

El problema que tengo es que me devuelve siempre el siguiente error:

Fatal error: Uncaught exception 'PrestaShopException' with message 'Can't save Order Payment' 

¿Alguien me podría decir como solucionarlo?

Gracias!!
