Unable to get response in JSON format with POST/PUT requests for adding/updating a Product to the category

Reference link: http://devdocs.magento.com/swagger/index.html#/

API: catalogCategoryLinkRepositoryV1 -> /V1/categories/{categoryId}/products

End point URL -> http:///rest/default/V1/categories/4/products


Content-Type: application/json Authorization:

Request body:

  "productLink": {
    "sku": "Happiest_Minds_Bag",
    "position": 0,
    "categoryId": "4",
    "extensionAttributes": {}

Response: "true"

The response which I get is a plain string "true" with status code "200 OK". But for any other error status code for this request I get a proper JSON response.

Why am I not getting response in JSON format for status code "200 OK"?


you need to add 'Accept' => 'application/json', 'Content-Type' => 'application/json'

for example,

$token = '4hmpioj8qvtgh1d06ujgg52a52yqbmye';
$httpHeaders = new \Zend\Http\Headers();

   'Authorization' => 'Bearer ' . $token,
   'Accept' => 'application/json',
   'Content-Type' => 'application/json'

  • We did the same but still we are getting the same "true" as response 'Authorization' => 'Bearer ' . $token, 'Accept' => 'application/json', 'Content-Type' => 'application/json' – Giri-happiestminds Jul 8 '16 at 7:45

If you wish to receive a JSON response, you must set the Accept header of your request to application/json.

  • Tried setting Accept: application/json as header. Still the response is string "true". – Giri-happiestminds Jul 8 '16 at 6:52
  • The string "true" IS json. That's what you'd get from json_encode(true). It sounds like you're expecting the object you created back, but doesn't sound like that's how it works. – Peter O'Callaghan Jul 8 '16 at 13:49
  • I am trying to parse it by using JAVA but getting exception because of a simple string. We are expecting the format in {"employees":[ {"firstName":"John", "lastName":"Doe"}, {"firstName":"Anna", "lastName":"Smith"}, {"firstName":"Peter", "lastName":"Jones"} ]} – Giri-happiestminds Jul 25 '16 at 8:17
