ISSUE API PRESTASHOP 1.7 - prestashop

Question

I currently have a problem with the prestashop API.
I'm trying to update the amount of a combination of a product.
<?php
$request = new HttpRequest();
$request->setUrl('https://myurl.com/api/combinations/15544');
$request->setMethod(HTTP_METH_PUT);
$request->setQueryData(array(
'io_format' => 'JSON'
));
$request->setHeaders(array(
'cache-control' => 'no-cache',
'Connection' => 'keep-alive',
'Accept-Encoding' => 'gzip, deflate',
'Host' => 'myurl.com',
'Cache-Control' => 'no-cache',
'Accept' => '*/*',
'User-Agent' => 'PostmanRuntime/7.19.0',
'Authorization' => 'Basic HIDDEN',
'Content-Type' => 'application/xml'
));
$request->setBody('<?xml version="1.0" encoding="UTF-8"?>
<prestashop xmlns:xlink="http://www.w3.org/1999/xlink">
<combination>
<id>15544</id>
<quantity>105</quantity>
<location></location>
<ean13></ean13>
<isbn></isbn>
<upc></upc>
<upplier_reference></upplier_reference>
<wholesale_price></wholesale_price>
<price></price>
<weight></weight>
<unit_price_impact></unit_price_impact>
<minimal_quantity>1</minimal_quantity>
<minimal_quantity>1</minimal_quantity>
<id_product>195</id_product>
<reference>E1903XLN</reference>
</combination>
</prestashop>');
try {
$response = $request->send();
echo $response->getBody();
} catch (HttpException $ex) {
echo $ex;
}
The response from the server is correct.
When I get the declination with a get here is the return:
{
"combination": {
"id": 15544,
"id_product": "195",
"location": "",
"ean13": "",
"isbn": "",
"upc": "",
"quantity": "105",
"reference": "E1903XLN",
"supplier_reference": "",
"wholesale_price": "0.000000",
"price": "0.000000",
"ecotax": "0.000000",
"weight": "0.000000",
"unit_price_impact": "0.000000",
"minimal_quantity": "1",
"low_stock_threshold": null,
"low_stock_alert": "0",
"default_on": null,
"available_date": "0000-00-00",
"associations": {
"product_option_values": [
{
"id": "28"
},
{
"id": "32"
}
]
}
}
}
Nevertheless on prestashop in the backoffice I do not see the changes:

Do you have an idea or solution ?
Thanks a lot for your help

Answer 1

To set an update of stock quantity for your combination you need to talk with the object StockAvailable.
Have a nice day :) !
