Create an odoo order and invoice it via external API

I'm trying to integrate an third party application with odoo, the application should create the order and confirm it, to generate the invoice, the order creation works perfectly, when executing the create_invoices nothing shows and no errors appears.

require_once('ripcord/ripcord.php');

$url = "http://127.0.0.1:8069";
$db = "odoo";
$password = "";
$username = "";

$common = ripcord::client("$url/xmlrpc/2/common");
$uid = $common->authenticate($db, $username, $password, array());
$models = ripcord::client("$url/xmlrpc/2/object");



$order_data = array(
    'partner_id' => 12, // Customer ID 
    'date_order' => date('Y-m-d'), // Order Date 
    // 'pricelist_id' => 1, // Price List ID 
    'state' => 'draft', // Order Status (draft) 

    'order_line' => array(array(0, 0, array( // Order Line Items 

        'product_id' => 2, // Product ID 
        'name' => 'Product Name', // Product Name  
        'product_uom_qty' => 5.00, // Quantity of Product  
        'price_unit' => 10.00, // Unit Price of Product  

    )))
);

$order_id = $models->execute_kw($db, $uid, $password, 'sale.order', 'create', array($order_data));

// Confirm Order and Create Invoice

if ($order_id) {

    $confirmOrder = $models->execute_kw($db, $uid, $password, 'sale.order', 'action_confirm', array($order_id));

    if ($confirmOrder) {

        $invoiceCreate = $models->execute_kw(
            $db,
            $uid,
            $password,
            'sale.advance.payment.inv',
            'create_invoices',
            array(
                'sale_order_ids' =>
                array(
                    0 =>
                    array(
                        0 => 6,
                        1 => false,
                        2 =>
                        array(
                            0 => $order_id,
                        ),
                    ),
                ),
                'advance_payment_method' => 'delivered',
                'deduct_down_payments' => true,
                'product_id' => false,
                'fixed_amount' => 0,
                'amount' => 0,
                'deposit_account_id' => false,
                'deposit_taxes_id' =>
                array(
                    0 =>
                    array(
                        0 => 6,
                        1 => false,
                        2 => array(),
                    ),
                ),
            )
            
            ,
            array(
                "context" => array(
                    'active_model' => "sale.order",
                    "allowed_company_ids" => array(1),
                    'active_id' => $order_id, "active_ids" => array($order_id)
                )
            )
        );

        if ($invoiceCreate) {
            
            echo "Order and Invoice #$invoiceCreate for Order #$order_id created successfully!\n";
        } else {
            echo "Error creating invoice!";
        }
    } else {
        echo "Error confirming order!";
    }
} else {
    echo "Error creating order!";
}

When calling create_invoices, Odoo will consider the first parameter as ids, to see the function call details change the log_level to debug

You should see the following debug message:

DEBUG demo16 odoo.api: call sale.advance.payment.inv('s', 'a', 'l', 'e', '_', 'o', 'r', 'd', 'e', 'r', '_', 'i', 'd', 's').create_invoices('advance_payment_method', 'deduct_down_payments', 'product_id', 'fixed_amount', 'amount', 'deposit_account_id', 'deposit_taxes_id')

Odoo will fail to call create_invoices function.

To fix the issue you can call the create function to get a wizard record id then call the create_invoices

Example:

$wizard_ids = $models->execute_kw(
    $db,
    $uid,
    $password,
    'sale.advance.payment.inv',
    'create',
    array(array(
        'sale_order_ids' => array($order_id),
    )),
    array(
        "context" => array(
            'active_model' => "sale.order",
            "allowed_company_ids" => array(1),
            'active_id' => $order_id, "active_ids" => array($order_id)
        )
    )
);
    
$invoiceCreate = $models->execute_kw($db, $uid, $password, 'sale.advance.payment.inv', 'create_invoices', array($wizard_ids));
