บัญชีบริการคือบัญชีพิเศษของ Google ที่แอปพลิเคชันสามารถใช้เพื่อเข้าถึง Google APIs แบบเป็นโปรแกรมผ่าน OAuth 2.0 บัญชีบริการใช้ขั้นตอน OAuth 2.0 ที่ไม่ต้องมีการให้สิทธิ์เพิ่มเติม แต่จะใช้ไฟล์คีย์ที่เฉพาะแอปพลิเคชันของคุณเท่านั้นที่เข้าถึงได้ คู่มือนี้จะพูดถึงวิธีเข้าถึง Manufacturer Center API ด้วยบัญชีบริการ
ตอนนี้คุณจะเข้าถึงบัญชี Manufacturer Center ได้โดยใช้บัญชีบริการ โดยใช้ขั้นตอนข้อมูลเข้าสู่ระบบเริ่มต้นของแอปพลิเคชันของ Google หรือใช้ขั้นตอนของบัญชีบริการโดยตรง ตัวอย่าง Manufacturer Center API จะแสดงวิธีใช้ทั้ง 2 ขั้นตอนสำหรับข้อมูลเข้าสู่ระบบของบัญชีบริการในภาษาโปรแกรมที่รองรับแต่ละภาษา ดูตัวอย่างโค้ดเพื่อลองใช้บัญชีบริการใหม่ของคุณและเพื่อดูว่าคุณจะต้องทำการเปลี่ยนแปลงใดบ้างเพื่อใช้บัญชีบริการในโค้ดของคุณเอง
คำถามที่พบบ่อย
ฉันจะเข้าสู่ระบบอินเทอร์เฟซผู้ใช้บนเว็บ Manufacturer Center ด้วยบัญชีบริการได้ไหม
ไม่ได้ บัญชีบริการไม่ใช่บัญชี Google ปกติและจะเข้าถึงอินเทอร์เฟซผู้ใช้บนเว็บของ Manufacturer Center ไม่ได้

A service account uses an\nOAuth 2.0 flow that does not require additional authorization. Instead, it uses\na key file that only your application can access. This guide discusses how to\naccess the Manufacturer Center API with service accounts.\n| **Note:** Applications using service accounts for authentication can only access your own Manufacturer Center account. If you are writing a third-party application that needs access to your clients' Manufacturer Center accounts, see the [Authorizing Requests](/manufacturers/how-tos/authorizing) guide instead.\n\nPrerequisites\n-------------\n\n- A [Manufacturer Center](//manufacturers.google.com/) account.\n\nSteps to using a service account to access the Manufacturer Center API\n----------------------------------------------------------------------\n\n1. Generate service-account credentials or access the public credentials you've\n already generated. You will need to create an OAuth 2.0 Client ID and obtain\n a \\*.json private key file:\n\n 1. Go to the [Google API Console](https://console.cloud.google.com/apis/library).\n\n 2. Select a project in the drop-down menu at the top of the page. If you do\n not have one yet, create one by clicking **Create Project**.\n\n 3. If you have not already enabled the Manufacturer Center API for this\n project, then search for it in the list of Google APIs and enable it.\n\n 4. In the sidebar on the left, select **Credentials**.\n\n 5. To set up a service account, select **Create credentials** , and then\n **Service account key**.\n\n 1. On the next page, select **New service account** from the drop-down\n list.\n\n 2. Name the new service account. This\n also serves as the default username for the service account ID. Remember\n the service account ID for use later.\n\n | **Note:** The choice of role for the service account will not have any effect on what calls can be made to the Manufacturer Center API, as access to Manufacturer Center API methods is determined instead by the role associated with the service account ID in Manufacturer Center. If you are unsure what to pick, just pick Project►Viewer.\n\n 1. Select **JSON** for the key type, then click **Create**.\n\n 2. The **Create** button will change to **Creating...**, and once the key\n generation finishes, it will automatically download the private key as a\n \\*.json file.\n\n | **Important:** Protect the \\*.json key file that allows a service account to access the Google services for which it has been authorized. It is good practice to allow service accounts to only access one Google API each. This is a preventative measure to mitigate the amount of data an attacker can access in the situation that the service account's \\*.json key file is compromised.\n 1. You will be returned to the Credentials page, and you should see the new service account in the list of service account keys for your account.\n2. Add the new service account as a user to your Manufacturer Center account.\n If you are a third party developer, you will need to have your client do\n this step for you.\n\n 1. Go to your [Manufacturer Center account](//manufacturers.google.com/).\n\n 2. Go to the 'Users' list in the settings of your Manufacturer Center\n account.\n\n 3. Click the +User button, and use the service account ID as the email\n address for the new user.\n\n 4. Fill in the form with the [service account ID](#service-account-name),\n and select the desired user role(s). At least one must be chosen, and\n use of the `Accounts` service requires the Admin role.\n\n If you did not take note of the service account ID earlier, go to the\n [Service Accounts](https://console.developers.google.com/iam-admin/serviceaccounts/)\n administration page and select the project you created.\n\n 1. Click on the **Save** button. You will be returned to the list of users,\n and the service account ID should be listed with the chosen user role(s).\n\n 2. Repeat the process for all other service accounts you want to add.\n\n 3. View existing service account users by going to the Users tab. These\n will be users with an email address ending in 'gserviceaccount.com'.\n\n3. Now you can access your Manufacturer Center account using the service\n account either by using the [Google Application Default\n Credentials](/identity/protocols/application-default-credentials) flow or by\n using the [service account flow](/identity/protocols/OAuth2ServiceAccount)\n directly. The Manufacturer Center API [Samples](/manufacturers/libraries)\n show how to use both flows for service account credentials in each supported\n programming language. See the code samples to try out your new service\n account and to learn what changes you will need to use service accounts in\n your own code.\n\nFrequently asked questions\n--------------------------\n\n#### Can I log into the Manufacturer Center web user interface with my service account?\n\nNo, service accounts are not regular Google accounts and cannot access the\nManufacturer Center web user interface.\n\n#### How often do I need to refresh service account access tokens?\n\nAccess tokens expire one hour after they are issued by the Google OAuth 2.0\nAuthorization Server. When an access token expires, the application should use\nthe client library to fetch another access token."]]
