title: Magento 2 - REST API PUT product
body: <p>When I try to update a product, created via the REST V1 API, only the values are updated for de default website. Unfortunattely I can't find any possibility to send website id's within te json. Does anyone have experienced this before?</p>
  
  <p>The data I send for the update to /V1/products/123456:</p>
  
  <pre><code>{"product":{"sku":"123456","name":"D4D0123299","price":21,"type_id":"simple","custom_attributes":[],"extension_attributes":{"stock_item":{"use_config_manage_stock":1}}}}"
  </code></pre>
  
  <p>Linking the product to specific websites is done with a second request, after creating it via /V1/products, to /V1/products/123456/websites (POST) with this data foreach website:</p>
  
  <pre><code>"{"productWebsiteLink":{"sku":"D4D01232","websiteId":1}}"
  "{"productWebsiteLink":{"sku":"D4D01232","websiteId":2}}"
  </code></pre>
  
  <p>The <strong>Magento 2</strong> version is <strong>2.1.0</strong></p>
