Hi, I found out there is a method to do stock update on multiple product with only one request.

Maybe some of you already now the way but I didnt found it when I was searsching for. 
 

Solution

1) Create a web request to "http://your.shop.url/api/stock_availables/1&display=[id,quantity]&io_format=JSON" with your optional credentials.

2) Use method="PUT" and ContentType="application/xml"

3) Add the following XML content :

"<prestashop>\n" +
"  <stock_available>\n" +
"    <id>" + id_prod1 + "</id>\n" +
"    <id_product>" + id_prod1 + "</id_product>\n" +
"    <id_product_attribute>0</id_product_attribute>\n" +
"    <id_shop>1</id_shop>\n" +
"    <id_shop_group>0</id_shop_group>\n" +
"    <quantity>" + quantite1 + "</quantity>\n" +
"    <depends_on_stock>0</depends_on_stock>\n" +
"    <out_of_stock>" + (quantite1 == 0 ? 2 : 0) + "</out_of_stock>\n" +
"    <location></location>\n" +
"  </stock_available>\n" +
"  <stock_available>\n" +
"    <id>" + id_prod2 + "</id>\n" +
"    <id_product>" + id_prod2 + "</id_product>\n" +
"    <id_product_attribute>0</id_product_attribute>\n" +
"    <id_shop>1</id_shop>\n" +
"    <id_shop_group>0</id_shop_group>\n" +
"    <quantity>" + quantite2 + "</quantity>\n" +
"    <depends_on_stock>0</depends_on_stock>\n" +
"    <out_of_stock>" + (quantite2 == 0 ? 2 : 0) + "</out_of_stock>\n" +
"    <location></location>\n" +
"  </stock_available>\n" +
"</prestashop>";

Or create it with a loop :

private static string RequestXML(List<MyJson.Produit> list)
{
	var xml = "<prestashop>\n";
	foreach (var prod in list)
	{
		xml +=
		"  <stock_available>\n" +
		"    <id>" + prod.web_id + "</id>\n" +
		"    <id_product>" + prod.web_id + "</id_product>\n" +
		"    <id_product_attribute>0</id_product_attribute>\n" +
		"    <id_shop>1</id_shop>\n" +
		"    <id_shop_group>0</id_shop_group>\n" +
		"    <quantity>" + prod.quantite_commande + "</quantity>\n" +
		"    <depends_on_stock>0</depends_on_stock>\n" +
		"    <out_of_stock>" + (prod.quantite_commande == 0 ? 2 : 0) + "</out_of_stock>\n" +
		"    <location></location>\n" +
		"  </stock_available>\n";
	}
	return xml+"</prestashop>";
}

4) Send the request and wait for response.

5) Split the string response and check if every product's stock as been updated.

 

Performance

Using one request per product's stock 

     5 stock updated per second

Using one request for all the product's stock :

     From <1second to up to 10 seconds depending on the numbrer of stocks to update

With a good server and good connection.

Before that, I was sending 250+ requests in 90 seconds to sync web stock with real stock in the shop.

I really hope this will help someone.
