OAuth 服務帳戶流程
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
本指南將逐步說明如何使用服務帳戶，透過您自己的憑證設定 OAuth2 來存取 API。除非您撤銷或刪除 OAuth2 認證，否則這些步驟只需執行一次。
建立 OAuth2 憑證
按照連結的操作說明產生服務帳戶 ID 和 *.JSON 檔案，然後返回這個頁面。
使用 JSON 檔案設定用戶端程式庫
在 google_ads_config.rb 中設定下列鍵。
c.keyfile = 'path/to/keyfile.json'
c.impersonate = 'INSERT_EMAIL_ADDRESS_TO_IMPERSONATE_HERE'
