I am trying to get a download link of a file, but getting this error: invalid value 4.

{"type":"error","status":400,"code":"bad_request","context_info":{"errors":[{"reason":"invalid_parameter","name":"file_version_id","message":"Invalid value '4'."}]},"help_url":"http:\/\/developers.box.com\/docs\/#errors","message":"Bad Request","request_id":"48y8omgyw5auncay"}

here is my code sniped: 

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.box.com/2.0/files/" . $fileId . "/content?version=4");
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    "Authorization: Bearer " . $accessToken
));

// Receive server response ...
$server_output = curl_exec($ch);
$downloadDetails = json_decode($server_output);
curl_close($ch);

Not getting any idea why i am getting this. Can anyone help me out?

    Hi Alauddin

    For the version parameter you need a valid version ID.

    Use the https://developer.box.com/reference/get-files-id-versions endpoint to list older versions of your file and use the version ID of the one you want to download. 

    curl_setopt($ch, CURLOPT_URL, "https://api.box.com/2.0/files/" . $fileId . "/content?version=ADD_THE_CORRECT_VERSION_ID_HERE");

    Thanks Peter, I got the idea. But it is not returning json. How do i get the data as a json?

    hi

    Not sure what you mean? The endpoint you are using https://developer.box.com/reference/get-files-id-content/ returns a binary result, not a json

    If you are looking for file info rather than the actual content you can use this endpoint https://developer.box.com/reference/get-files-id/ or this one for versions https://developer.box.com/reference/get-files-id-versions-id/

    Best regards,

    Peter

    Sorry, I was talking about Get Download URL. It is returning data like below. Not returning json.

    The https://developer.box.com/reference/get-files-id-content endpoint will (almost) always return a 302 with location header instruction the client where to download the file.

    This endpoint will not return any json payload. Are you asking because the file you are trying to download is a json file? To read it you will need to download it first

    I am trying to get a downloadable URL which i will use on another API to store the file elsewhere (outside of box).
