Google Tag Manager API - 開發人員指南

這份開發人員指南將逐步說明存取、建立和管理應用程式所需的步驟代碼管理工具 API v2

簡介

本指南將逐步說明存取和設定 Google 代碼管理工具帳戶。完成本課程後，您會學到執行下列工作：

建立代碼管理工具服務物件。
驗證並授權使用者。
使用代碼管理工具 API 來存取及管理資源。

事前準備

開始本指南之前，建議您先熟悉 Google 代碼管理工具的操作方式：請造訪 Google 代碼管理工具說明中心。

使用測試帳戶

如要使用 Tag Manager API 建立、設定或刪除實體時，建議您利用測試程序實作並驗證程式碼讓他們使用服務帳戶使用測試帳戶可避免不慎誤報對有效帳戶所做的變更完成測試並確認程式碼後測試帳戶運作正常，接著透過實際帳戶進行實作

選取語言

請在下方選取您想要使用的程式設計語言：

計畫簡介

本指南中的範例程式是指令列應用程式。假設帳戶 ID，應用程式會尋找名為 Greetings 的容器並該容器中的通用 Analytics 代碼當使用者造訪 hello-world.html 時，代碼會傳送網頁瀏覽命中

如要開發這個應用程式，請按照下列步驟操作：

在 Google API 控制台中設定開發環境和專案。
建立代碼管理工具服務物件。
1. 授權存取代碼管理工具帳戶。
2. 建立代碼管理工具服務物件。
查詢 API、處理回應，然後輸出結果。
1. 取得初始化的代碼管理工具服務物件。
2. 使用代碼管理工具服務物件查詢代碼管理工具 API 可執行以下工作：
  1. 擷取 Greetings 容器已驗證的 Google 代碼管理工具帳戶
  2. 建立新工作區。
  3. 建立通用 Analytics 代碼。
  4. 請建立觸發條件來觸發代碼。
  5. 更新代碼以觸發觸發條件。

設定開發環境和專案

建立 Greetings 容器

本指南假設您擁有 Google 代碼管理工具帳戶且具備容器命名為 Greetings按照操作說明設定和工作流程 (網站) 建立「帳戶」和「容器」命名為 Greetings。

安裝用戶端程式庫

在開始之前，請先安裝 Google API 用戶端程式庫。

在 Google API 控制台中建立並設定專案

如要開始使用代碼管理工具 API 使用設定工具，會引導您在 Google API 控制台，啟用 API 並建立憑證。

本指南使用已安裝的應用程式驗證方式流程請按照以下操作說明建立專案憑證。時間系統提示，請為 APPLICATION 選取 Installed Application 和Other適用於已安裝的應用程式 TYPE。

在「憑證」頁面上，按一下「建立憑證」>OAuth 用戶端建立 OAuth 2.0 憑證，或依序選取 [建立憑證] > [建立憑證]。服務帳戶金鑰，以建立服務帳戶。
如果您已建立 OAuth 用戶端 ID，請選取應用程式類型。
填寫表單，然後按一下「建立」。

系統已列出應用程式的用戶端 ID 和服務帳戶金鑰「憑證」頁面。詳情請按一下用戶端 ID；參數會有所不同視 ID 類型而定，但可能包含電子郵件地址、用戶端密鑰 JavaScript 來源或重新導向 URI

點選「下載 JSON」，下載用戶端詳細資料按鈕。將這個檔案重新命名為「client_secrets.json」。這個檔案將成為以便進行身分驗證

建立代碼管理工具服務物件

您必須建立代碼管理工具 service 物件 API 要求。

建立代碼管理工具服務物件的必要步驟如下：

授權存取 Google 代碼管理工具帳戶。
將代碼管理工具服務物件執行個體化。

授權存取 Google 代碼管理工具帳戶

使用者啟動使用 Google Tag Manager API 建立的應用程式時，必須授予應用程式 Google 代碼管理工具存取權讓他們使用服務帳戶這項程序稱為授權。授權使用者為 OAuth 2.0。詳情請參閱「Tag Manager API 授權」一文。

以下程式碼使用專案和用戶端詳細資料驗證應用程式的使用者，並詢問代為存取 Google 代碼管理工具

應用程式會嘗試開啟預設瀏覽器，並瀏覽使用者連往 google.com 代管的網址系統會提示使用者登入授予應用程式代碼管理工具帳戶存取權。授予後，應用程式會嘗試讀取瀏覽器視窗中的代碼，然後關閉在視窗上

注意：如果發生錯誤，應用程式而是提示使用者透過指令互動

查詢代碼管理工具 API

代碼管理工具服務物件可用來查詢代碼管理工具 API導入範例計畫：

擷取 Greetings 容器
建立通用 Analytics 代碼
建立觸發條件以觸發代碼
更新代碼以觸發觸發條件

1. 擷取 Greetings 容器

下列函式說明代碼管理工具服務物件的可呈現方式用來查詢代碼管理工具 API 來列出帳戶的所有容器擷取名為 Greetings 的容器。

您可以在 Google Tag Manger 的網址列網頁介面。例如網址中的帳戶 ID https://tagmanager.google.com/#/admin/accounts/112233/containers/2292948/users 為 112233。

Python

def FindGreetingsContainer(service, account_path):
  """Find the greetings container.

  Args:
    service: the Tag Manager service object.
    account_path: the path of the Tag Manager account from which to retrieve the
      Greetings container.

  Returns:
    The greetings container if it exists, or None if it does not.
  """
  # Query the Tag Manager API to list all containers for the given account.
  container_wrapper = service.accounts().containers().list(
      parent=account_path).execute()

  # Find and return the Greetings container if it exists.
  for container in container_wrapper['container']:
    if container['name'] == 'Greetings':
      return container
  return None

JavaScript

/**
 * Returns the greetings container if it exists.
 *
 * @param {string} accountPath The account which contains the Greetings
 * container.
 * @return {Promise} A promise to find the greetings container.
 */
function findContainer(accountPath, containerName) {
  console.log('Finding container in account:' + accountPath);
  var request = gapi.client.tagmanager.accounts.containers.list({
    'parent': accountPath
  });
  return requestPromise(request)
      .then((response) => {
        var containers = response.container || [];
        var container =
            containers.find((container) => container.name === containerName);
        return container ||
            Promise.reject('Unable to find ' + containerName +' container.');
      });
}

接著更新程式的主要執行分支，以呼叫指定代碼管理工具的 findGreetingsContainer 函式 accountId。例如：

Python

def main(argv):
  # Get tag manager account ID from command line.
  assert len(argv) == 2 and 'usage: gtm-api-hello-world.py <account_id>'
  account_id = str(argv[1])
  account_path = 'accounts/%s' % account_id

  # Define the auth scopes to request.
  scope = ['https://www.googleapis.com/auth/tagmanager.edit.containers']

  # Authenticate and construct service.
  service = GetService('tagmanager', 'v2', scope, 'client_secrets.json')

  # Find the greetings container.
  container = FindGreetingsContainer(service, account_path)

if __name__ == '__main__':
  main(sys.argv)

JavaScript

/**
 * Interacts with the tagmanager api v2 to create a container, workspace,
 * trigger, and tag.
 *
 * @return {Promise} A promise to run the tag manager example.
 */
function runTagManagerExample() {
  return new Promise((resolve, reject) => {
    console.log('Running Tag Manager Example.');
    var trigger = null;
    var workspace = null;
    findContainer(ACCOUNT_PATH, CONTAINER_NAME)
        .catch(handleError);
    resolve();
  });
}

2. 建立新工作區

下列程式碼片段使用 Tag Manager API 建立新工作區，我們使用管理觸發條件和代碼的相關變更您可以查看工作區建立方法參考資料。建立工作區

Python

def CreateWorkspace(service, container):
    """Creates a workspace named 'my workspace'.

    Args:
      service: the Tag Manager service object.
      container: the container to insert the workspace within.

    Returns:
      The created workspace.
    """
    return service.accounts().containers().workspaces().create(
        parent=container['path'],
        body={
            'name': 'my workspace',
        }).execute()

JavaScript

/**
 * Creates a workspace in the Greetings container.
 *
 * @param {Object} container The container to create a new workspace.
 * @return {Promise} A promise to create a workspace.
 */
function createWorkspace(container) {
  console.log('Creating workspace in container:' + container.path);
  var request = gapi.client.tagmanager.accounts.containers.workspaces.create(
    { 'parent': container.path },
    { name: WORKSPACE_NAME, description: 'my workspace created via api' });
  return requestPromise(request);
}

3. 建立通用 Analytics 代碼

下列程式碼片段使用 Tag Manager API 建立通用的 Analytics 代碼。您可以檢查一下建立代碼方法參考資料。在建立代碼和代碼字典參考資料時設定。

Python

def CreateHelloWorldTag(service, workspace, tracking_id):
  """Create the Universal Analytics Hello World Tag.

  Args:
    service: the Tag Manager service object.
    workspace: the workspace to create a tag within.
    tracking_id: the Universal Analytics tracking ID to use.

  Returns:
    The created tag.
  """

  hello_world_tag = {
      'name': 'Universal Analytics Hello World',
      'type': 'ua',
      'parameter': [{
          'key': 'trackingId',
          'type': 'template',
          'value': str(tracking_id),
      }],
  }

  return service.accounts().containers().workspaces().tags().create(
      parent=workspace['path'],
      body=hello_world_tag).execute()

JavaScript

/**
 * Creates a universal analytics tag.
 *
 * @param {Object} workspace The workspace to create the tag
 * @return {Promise} A promise to create a hello world tag.
 */
function createHelloWorldTag(workspace) {
  console.log('Creating hello world tag');
  var helloWorldTag = {
    'name': 'Universal Analytics Hello World',
    'type': 'ua',
    'parameter':
    [{ 'key': 'trackingId', 'type': 'template', 'value': 'UA-1234-5' }],
  };
  var request =
    gapi.client.tagmanager.accounts.containers.workspaces.tags.create(
      { 'parent': workspace.path }, helloWorldTag);
  return requestPromise(request);
}

4. 建立觸發條件以觸發代碼

建立代碼後，下一步就是建立觸發條件並在任何網頁上觸發

這個觸發條件將命名為「Hello World Trigger」，並會觸發即可。例如：

Python

def CreateHelloWorldTrigger(service, workspace):
  """Create the Hello World Trigger.

  Args:
    service: the Tag Manager service object.
    workspace: the workspace to create the trigger within.

  Returns:
    The created trigger.
  """

  hello_world_trigger = {
      'name': 'Hello World Rule',
      'type': 'PAGEVIEW'
  }

  return service.accounts().containers().workspaces().triggers().create(
      parent=workspace['path'],
      body=hello_world_trigger).execute()

JavaScript

/**
 * Creates a page view trigger.
 *
 * @param {Object} workspace The workspace to create the trigger in.
 * @return {Promise} A promise to create a page view trigger.
 */
function createHelloWorldTrigger(workspace) {
  console.log('Creating hello world trigger in workspace');
  var helloWorldTrigger = { 'name': 'Hello World Trigger', 'type': 'PAGEVIEW' };
  var request =
    gapi.client.tagmanager.accounts.containers.workspaces.triggers.create(
      { 'parent': workspace.path }, helloWorldTrigger);
  return requestPromise(request);
}

5. 更新代碼以觸發觸發條件

建立代碼和觸發條件後，就必須將每個代碼和每個觸發條件建立關聯其他。方法是將 triggerId 新增至與代碼相關聯的 firingTriggerIds。例如：

注意：如要簡化這項程序，請先建立觸發條件，然後在建立觸發條件時指定 triggerId 代碼，而不要執行其他更新。

Python

def UpdateHelloWorldTagWithTrigger(service, tag, trigger):
  """Update a Tag with a Trigger.

  Args:
    service: the Tag Manager service object.
    tag: the tag to associate with the trigger.
    trigger: the trigger to associate with the tag.
  """
  # Get the tag to update.
  tag = service.accounts().containers().workspaces().tags().get(
      path=tag['path']).execute()

  # Update the Firing Trigger for the Tag.
  tag['firingTriggerId'] = [trigger['triggerId']]

  # Update the Tag.
  response = service.accounts().containers().workspaces().tags().update(
      path=tag['path'],
      body=tag).execute()

JavaScript

/**
 * Updates a tag to fire on a particular trigger.
 *
 * @param {Object} tag The tag to update.
 * @param {Object} trigger The trigger which causes the tag to fire.
 * @return {Promise} A promise to update a tag to fire on a particular trigger.
 */
function updateHelloWorldTagWithTrigger(tag, trigger) {
  console.log('Update hello world tag with trigger');
  tag['firingTriggerId'] = [trigger.triggerId];
  var request =
    gapi.client.tagmanager.accounts.containers.workspaces.tags.update(
      { 'path': tag.path }, tag);
  return requestPromise(request);
}

接著更新程式的主要執行分支版本，以呼叫建立和來更新函式例如：

Python


def main(argv):
  # Get tag manager account ID from command line.
  assert len(argv) == 2 and 'usage: gtm-api-hello-world.py <account_id>'
  account_id = str(argv[1])
  account_path = 'accounts/%s' % account_id

  # Define the auth scopes to request.
  scope = ['https://www.googleapis.com/auth/tagmanager.edit.containers']

  # Authenticate and construct service.
  service = GetService('tagmanager', 'v2', scope, 'client_secrets.json')

  # Find the greetings container.
  container = FindGreetingsContainer(service, account_path)

  # Create a new workspace.
  workspace = CreateWorkspace(service, container)

  # Create the hello world tag.
  tag = CreateHelloWorldTag(
      service, workspace, 'UA-1234-5')

  # Create the hello world Trigger.
  trigger = CreateHelloWorldTrigger(
      service, workspace)

  # Update the hello world tag to fire based on the hello world tag.
  UpdateHelloWorldTagWithTrigger(service, tag, trigger)
if __name__ == '__main__':
  main(sys.argv)

JavaScript

/**
 * Interacts with the tagmanager api v2 to create a container, workspace,
 * trigger, and tag.
 *
 * @return {Promise} A promise to run the tag manager example.
 */
function runTagManagerExample() {
  return new Promise((resolve, reject) => {
    console.log('Running Tag Manager Example.');
    var trigger = null;
    var workspace = null;
    findContainer(ACCOUNT_PATH, CONTAINER_NAME)
        .then(createWorkspace)
        .then((createdWorkspace) => {
          workspace = createdWorkspace;
          return createHelloWorldTrigger(workspace);
        })
        .then((createdTrigger) => {
          trigger = createdTrigger;
          return createHelloWorldTag(workspace);
        })
        .then((createdTag) => {
          return updateHelloWorldTagWithTrigger(createdTag, trigger);
        })
        .catch(handleError);
