# fields

## Overview

You can view the fields of project-specific logs in Effective Log Search & Analytics.

Using this API, you can look up log fields that occur in a specified time period. For fields with ".raw" appended, you should only use them by appending ".raw" to the field name when using the “sorts” feature at /api/v1/logs/search.

### Request example

```
import hashlib
import hmac
import base64
import time
import requests

def make_signature(access_key, secret_key, timestamp, url):
    timestamp = str(timestamp)
    secret_key = bytes(secret_key, 'UTF-8')
    method = "GET"

    message = method + " " + url + "\n" + timestamp + "\n" + access_key
    message = bytes(message, 'UTF-8')
    signingKey = base64.b64encode(hmac.new(secret_key, message, digestmod=hashlib.sha256).digest())
    return signingKey.decode('UTF-8')

def fields():
    baseurl = "https://elsa.apigw.ntruss.com" #{OpenAPI endpoint}
    url = "/api/v1/fields?projectKey=Pbxxxxx_elsa-test&projectId=8171&from=1381190400000&to=1381190400000"

    timestamp = int(time.time() * 1000)

    signature = make_signature(access_key, secret_key, timestamp, url)

    url = baseurl + url
    headers = {
