I am using Amazon Product Advertising API, I want to retrieve all products of a category. What I want to know is can I only provide a category without passing any Keyword into the ItemSearch operation and retrieve the complete set of product records including their sub-category products.
I tried passing this parameter in an array without supplying a 'Keyword' item:
$category = 'Software';
$single = array(
"Operation" => "ItemSearch",
"SearchIndex" => $category,
"Condition" => "All",
"ResponseGroup" => "Medium,Reviews"
);
But it does not work. Please help me.
Let me explain again in short that all I want is to get the complete list of Products by passing any category without passing any Keyword.
