認証

認証には、このコードを使用してください:

# With shell, you can just pass the correct header with each request
curl "api_endpoint_here" \
  -H "Authorization: Bearer i18n_your_api_key_here"

const headers = {
  'Authorization': 'Bearer i18n_your_api_key_here',
  'Content-Type': 'application/json'
};

fetch('api_endpoint_here', { headers })
  .then(response => response.json())
  .then(data => console.log(data));

import requests

headers = {
    'Authorization': 'Bearer i18n_your_api_key_here',
    'Content-Type': 'application/json'
}

response = requests.get('api_endpoint_here', headers=headers)
print(response.json())

package main

import (
    "net/http"
)

func main() {
    client := &http.Client{}
    req, _ := http.NewRequest("GET", "api_endpoint_here", nil)
    req.Header.Add("Authorization", "Bearer i18n_your_api_key_here")
    
    resp, _ := client.Do(req)
    defer resp.Body.Close()
}

i18n_your_api_key_hereをあなたのAPIキーに置き換えることを忘れないでください。

i18n-agent account dashboard アカウントダッシュボードからAPIキーを取得できます。これを使用してAPIへのアクセスを許可します。

APIキーは、以下のようなヘッダーでサーバーへのすべてのAPIリクエストに含める必要があります:

Authorization: Bearer i18n_your_api_key_here

i18n_your_api_key_here

をあなたの個人APIキーに置き換える必要があります。

You must replace i18n_your_api_key_here with your personal API key.
