MULTIPLE COMBINATIONS VIA WEBSERVICE

[leonardomarinio]

I try to send via webservice in presashop 1.7.8 php 7.4 the product combinations, they are already created correctly, but when I send the association as indicated in combinations https://devdocs.prestashop-project.org/1.7/webservice/resources/combinations / Sending the following xml (using the prestapyt directory)

<prestashop xmlns:xlink='http://www.w3.org/1999/xlink'>
   <combination>
       <id_product>3666</id_product>
       <location></location>
       <ean13></ean13>
       <isbn></isbn>
       <upc></upc>
       <mpn></mpn>
       <quantity>1300</quantity>
       <reference></reference>
       <supplier_reference></supplier_reference>
       <wholesale_price></wholesale_price>
       <price></price>
 <ecotax></ecotax>
       <weight></weight>
       <unit_price_impact></unit_price_impact>
       <minimal_quantity>1</minimal_quantity>
       <low_stock_threshold></low_stock_threshold>
       <low_stock_alert></low_stock_alert>
       <default_on></default_on>
       <available_date></available_date>
       <associations>
           <product_option_values>
               <product_option_value>
                   <id>5550</id>
                   <id>5496</id>
                   <id>5959</id>
                   <id>6087</id>
               </product_option_value>
           </product_option_values>
       </associations>
    </combination>
</prestashop>

 

I can't find where the error could be since it doesn't return an error but it creates a single combination with the first id indicated. What are we doing wrong?
