### Get a Submission [GET]
Returns details about submission.

Just like in [create submission](/#submission-submission-post) you can receive Base64 encoded data for every text type attribute (check the [table](#submission-submission) to see which attributes are text type). By default, this parameter is set to `false` and Judge0 will send you raw data.

By default Judge0 is sending 8 attributes for submission. By sending `fields` query parameter you can specify exactly which attributes you want from Judge0. Special value `*` will return all available attributes.

+ Parameters
    + token (required, string, `d85cd024-1548-4165-96c7-7bc88673f194`) ... Token of submission. You got this token when you created submission.
    + base64_encoded (optional, boolean, `false`) ... Set to `true` if you want to receive Base64 encoded data from Judge0. You should set this to `true` if you expect the program's stdout to contain non-printable characters or if you expect the compiler to output non-printable characters during a compile error (GCC does this, for instance).
    + fields = `stdout,time,memory,stderr,token,compile_output,message,status` (optional, string, `stdout,stderr,status_id,language_id`) ... Return only the desired attributes.

+ Response 200 (applicatiion/json)
    {
        "stdout": "hello, world\n",
        "status_id": 5,
        "language_id": 4,
        "stderr": null
    }

+ Response 200 (application/json)
    This is the default response. Leave `fields` parameter empty if you want to get default response.
    + Body
