Magento – Magento 2 Product Search REST API Collection Filtering

There are default REST APIs in Magento2.

1. website ID (or store ID) we have multisite : To filter according to the store or website there is no any REST APIs. To get list of product according to store or website reuired "REST Schema Endpoint Format". For example to get list of product for a single store we use the following call

   http://{baseurl}/rest/V1/products?searchCriteria[pageSize]=10
   

   suppose you have another store with store code "store2". then we use following url

   http://{baseurl}/rest/store2/V1/products?searchCriteria[pageSize]=10
   

   For more detail REST Schema end point

List of avail APIs Megento2 Rest Apis

For According to category use following url http://myfashionstore.com/rest/store2/V1/products?searchCriteria[pageSize]=10&searchCriteria[filterGroups][0][filters][0][field]=category_id&searchCriteria[filterGroups][0][filters][0][value]=6

Solution came suddenly. It looks like url and params were encoded wrongly. I use this library to ease rest api coding https://github.com/springimport/magento2-api-v1

    use springimport\magento2\apiv1\Configuration,
        springimport\magento2\apiv1\ApiFactory;

    ...

    $configuration = new Configuration;
    $configuration->setBaseUri('https://dev.devserver.com/index.php/rest/V1/customers/1');
    $configuration->setConsumerKey('aca1rh9env59axm0ob48xfu62t9s4a5e');
    $configuration->setConsumerSecret('dgn4y1ejfu9aixb5mrio4kbsor5tq208');
    $configuration->setToken('fi5keosdaod7hgqsyhv9i8o2yxvk0dqx');
    $configuration->setTokenSecret('ugeovkdcyvl3q2wc0kxjmgiprobtr63g');

    $apiFactory = new ApiFactory($configuration);
    $client = $apiFactory->getApiClient();

    $res = $client->request('GET', 'https://dev.devserver.com/index.php/rest/V1/products?searchCriteria[filter_groups][0][filters][0][field]=category_id&searchCriteria[filter_groups][0][filters][0][value]=10', ['verify' => false]);
    echo $res->getStatusCode();
    // 200
    echo $res->getHeaderLine('content-type');
    // 'application/json; charset=utf8'
    echo $res->getBody();
    die();
