建議使用 Google API 用戶端程式庫設定 Content API for Shopping。本指南以 Python Content API 用戶端程式庫為例，但這些程式庫適用於許多熱門程式設計語言，可簡化常見的 API 工作，例如驗證、傳送要求及剖析回應。如需其他語言的用戶端程式庫設定說明，請參閱 GitHub 上 googleads/googleads-shopping-samples 存放區中，該語言的 README.md。

This guide uses the Python Content API client\nlibraries as an example, but they're available for many popular programming\nlanguages and simplify common API tasks like authentication, sending requests,\nand parsing responses. For help setting up client libraries for\nother languages, see the **README.md** for the language within the\n[googleads/googleads-shopping-samples](//github.com/googleads/googleads-shopping-samples)\nrepo on GitHub.\n| **Note:** You need to install several required libraries to use the sample code in Python. For this reason, we recommend creating a Python virtual environment before you proceed. For more information, see [Installing packages using pip and virtual environments](//packaging.python.org/guides/installing-using-pip-and-virtual-environments/).\n\nTo set up the Google API client library for Python, complete the following steps:\n\n1. Create a directory for the client library's configuration and authentication\n files. Within your home directory, create the following directories:\n\n **\\~/shopping-samples/content/**\n | **Note:** This path, as well as the filename for the **merchant-info.json** file created in step 5, are defined in the **python/shopping/content/common.py** file within the Content API samples directory downloaded in step 7.\n2. To download your service account credentials, complete the following steps:\n\n 1. Go to the [Google API library](//console.cloud.google.com/apis/library).\n 2. Select a project in the menu at the top of the page. If you don't have one yet, create one by clicking **New project**.\n 3. If you haven't already enabled the Content API for Shopping for this project, then search for it in the list of Google APIs and enable it.\n 4. In the sidebar on the left, select **Credentials**. You may need to click the left-pointing arrow at the top left to see this.\n 5. To set up a service account, select **Create credentials** , and then **Service account**.\n 6. Name the new service account. This also serves as the default username for the service account ID. Record the service account ID, including the part after the '@' character, for later use. Click **Create** , then go through the optional steps of granting access to project and users, and click **Done**.\n 7. You will be directed to the Service Accounts page where your new service account can be accessed.\n3. To obtain a JSON private key, click the service account, then the **Keys**\n tab. Click **Add key** \\\u003e **Create new key** , and then select JSON as the\n key type. Click **Create** to download the private key to your computer.\n The new key downloads automatically.\n\n4. Rename the downloaded credentials file to **service-account.json**.\n\n | **Note:** This filename is defined in the **_constants.py** file, which is located in **python/shopping/content/** within the Content API samples directory downloaded in step 7.\n5. Move the **service-account.json** file to your\n **\u003cvar translate=\"no\"\u003ehome directory\u003c/var\u003e/shopping-samples/content/**.\n\n6. In your **\u003cvar translate=\"no\"\u003ehome directory\u003c/var\u003e/shopping-samples/content/** , create an\n empty **merchant-info.json** file.\n\n7. In **merchant-info.json**, add the following text:\n\n {\n \"merchantId\": \u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-err\"\u003eyour\u003c/span\u003e\u003cspan class=\"devsite-syntax-w\"\u003e \u003c/span\u003e\u003cspan class=\"devsite-syntax-err\"\u003eMercha\u003c/span\u003e\u003cspan class=\"devsite-syntax-kc\"\u003ent\u003c/span\u003e\u003cspan class=\"devsite-syntax-w\"\u003e \u003c/span\u003e\u003cspan class=\"devsite-syntax-err\"\u003eCe\u003c/span\u003e\u003cspan class=\"devsite-syntax-kc\"\u003enter\u003c/span\u003e\u003cspan class=\"devsite-syntax-w\"\u003e \u003c/span\u003e\u003cspan class=\"devsite-syntax-err\"\u003emercha\u003c/span\u003e\u003cspan class=\"devsite-syntax-kc\"\u003ent\u003c/span\u003e\u003cspan class=\"devsite-syntax-w\"\u003e \u003c/span\u003e\u003cspan class=\"devsite-syntax-err\"\u003eID\u003c/span\u003e\u003c/var\u003e,\n \"accountSampleUser\": \"\u003cvar translate=\"no\"\u003ethe email address associated with your Merchant Center account\u003c/var\u003e\"\n }\n\n8. Add the new service account as a user to your Merchant Center account. If you\n are a third-party developer, you will need to have your client do this step\n for you.\n\n 1. Go to your [Merchant Center account](//merchants.google.com).\n 2. In the settings of your Merchant Center account, select **People and\n access**.\n 3. Click **+ Add person** and use the service account ID as the email address\n for the new user.\n\n | **Note:** If you did not take note of the service account ID earlier, go to the [Service Accounts administration\n | page](//console.developers.google.com/iam-admin/serviceaccounts) and select the project you created.\n 4. The use of the `Accounts` service requires Admin access, so select\n **Admin**.\n\n 5. Click **Add user** to save preferences and be returned to the list of\n users. The service account ID is listed with the chosen user role.\n\n 6. Repeat the process for all other service accounts you want to add.\n\n9. Clone (or download and unzip) the\n [googleads/googleads-shopping-samples](//github.com/googleads/googleads-shopping-samples)\n GitHub repo to any location on your computer; it does not have to be in your\n home directory or in **\\~/shopping-samples/content/**.\n\n10. If you downloaded and unzipped the repo, instead of cloning it, rename the\n unzipped directory to **googleads-shopping-samples**.\n\n11. To install the required sample dependencies, in a terminal window,\n navigate to **googleads-shopping-samples/python/** and run:\n\n pip install -r requirements.txt\n\nYou now have the Google API client library for Python configured and ready to use with the Content API. In the next section, you'll create and send a request to insert a new product."]]
