API 金鑰與建立金鑰時所屬的 Google Cloud 專案相關聯。如果您的 API 需要 API 金鑰，您就必須提供 API 使用者 Cloud Endpoints 服務建立時所屬專案中的金鑰，或是讓 API 使用者能夠在自己的專案中啟用您的 API 及建立 API 金鑰。 Google Cloud本頁說明如何授權使用者啟用您的 API。
授予存取權
Endpoints 會使用 Identity & Access Management (IAM)服務消費者角色，允許您Google Cloud 專案成員以外的人員在自己的 Google Cloud專案中啟用您的 API。本節說明如何使用Google Cloud 控制台或 Google Cloud CLI 授予存取權。
Google Cloud 控制台
在 Google Cloud 控制台中，依序前往您專案的「Endpoints」 >「Services」頁面。
