メッセージを送信する

ユーザーからメッセージを受信したら、レスポンスを送信して会話を続行できます。ユーザーにメッセージを送信できるのは、最後のメッセージから 30 日後までです。

エージェントは、メッセージを送受信することでユーザーと通信します。ユーザーにメッセージを送信するため、エージェントはビジネス メッセージにメッセージ リクエストを送信します。

注: コマンドラインを使用して API 呼び出しを行う場合は、oauth 2l をインストールします。

メッセージを送信するには、以下を含む HTTP POST リクエストを Business Messages API に送信します。

• 一意のメッセージ ID
• 会話 ID
• メッセージの内容

Business Messages API はユーザーにメッセージを送信すると、200 OK を返します。メッセージに必要な値が欠落している場合、API は 400 エラーを返します。メッセージで無効な認証情報が使用されている場合、API から 401 エラーが返されます。

メッセージ配信の問題をデバッグするには、Business Communications デベロッパー コンソールのログページを使用します。

フォールバック戦略

送信しようとしたメッセージをユーザーのデバイスがサポートしていない場合（ユーザーが返信の候補に対応していない場合など）は、API から 400 (FAILED PRECONDITION) エラーが返されます。ただし、送信するメッセージごとに fallback テキストを指定すると、サポートされていないメッセージ タイプを回避できます。fallback テキストを指定すると、ユーザーのデバイスがメッセージ タイプをサポートしていない場合でも、API は 200 OK レスポンスを返します。

ユーザーが、デバイスが fallback テキストをサポートしていないにもかかわらずメッセージを受信した場合、デバイスには代わりに fallback テキストが表示されます。これにより、会話の流れを中断したり、400 (FAILED PRECONDITION) エラーの処理と代替メッセージの特定に余分な時間をかけたりすることなく、プロアクティブな方法で会話を継続できます。

いかなるメッセージの fallback テキストも、メッセージの機能を反映したものにする必要があります。たとえば

• 返信文やアクションの候補があるメッセージの場合は、fallback テキストにメッセージ テキストを追加し、ユーザーが会話を続行する方法に関するガイダンスを含めます。
• リッチカードやカルーセルの場合は、fallback テキストにタイトルと説明を含め、画像やウェブサイトへのリンクを含めます。

fallback のテキストに改行を挿入するには、\n または \r\n を使用します。

代替テキストをテストする

エージェントを起動する前に、URL パラメータ forceFallback を true に設定してメッセージを送信することで、会話で代替テキストがどのように表示されるかをテストできます。代替テキストを強制的に適用すると、会話ではメインのメッセージ コンテンツ（次の例ではテキストと URL を開く候補）が無視され、代わりに代替テキストが表示されます。

注: forceFallback URL パラメータは、起動されたエージェントでは使用できません。

エージェントがメッセージを送信するときに、担当者（メッセージの構成者または自動化）を指定します。ビジネス メッセージは、HUMAN と BOT の担当者をサポートします。

自動化でメッセージを作成するときに BOT 担当者を指定します。自動化は、ユーザーにキュー内の場所を伝える自動返信機能、ユーザーの詳細に動的にアクセスできる複雑な自然言語理解エージェントなど、さまざまです。BOT の担当者を含むメッセージは、小さなアイコン とともに表示されます。このアイコンにより、ユーザーは使用する可能性のあるインタラクションの種類について予想しやすくなります。

人間のエージェントがメッセージを作成する場合にのみ、HUMAN 担当者を指定します。HUMAN 担当者からメッセージを送信する前に、REPRESENTATIVE_JOINED イベントを送信して、自由形式のメッセージや複雑なメッセージを送信できることをユーザーに知らせます。HUMAN 担当者から最後のメッセージを送信した後、REPRESENTATIVE_LEFT イベントを送信してユーザーに再度メッセージを伝えます。

たとえば、ユーザーがエージェントとの会話を開始し、エージェントが 2 分以内にライブのエージェントがいることをユーザーに知らせる自動メッセージを送信した場合、そのメッセージは BOT の担当者から送信されます。ライブ エージェントが参加する前に、REPRESENTATIVE_JOINED イベントを送信します。ライブ エージェントからのすべてのメッセージには、HUMAN 担当者から送信されたものとしてラベル付けする必要があります。ライブ エージェントが会話を終了したら、REPRESENTATIVE_LEFT イベントを送信します。以降のメッセージはすべて、別のライブ エージェントが会話に参加しない限り、BOT 担当者から送信されます。

注: Dialogflow インテグレーションで自動応答を有効にした場合も、ライブ対応のエージェントのリクエストの処理、適切な REPRESENTATIVE_JOINED と REPRESENTATIVE_LEFT のイベントの送信、HUMAN 担当者へのメッセージの送信は、デベロッパーが行う必要があります。

BOT 担当者と HUMAN 担当者間の移行に関する会話とコードのサンプルについては、bot からライブ エージェントへの引き継ぎをご覧ください。

代表者が BOT か HUMAN かにかかわらず、代表者の表示名とアバターを指定できます。表示名とアバターの両方がユーザーに表示されます。 アバター画像は 1,024 x 1,024 ピクセル、最大 50 KB とし、一般公開されている URL として指定する必要があります。アバター画像を指定しない場合は、エージェントのロゴが代表者のアバターに使用されます。

注: アバター画像では、写真内の代表者の描写など、個人情報をサポートしていません。アイコン、ロゴ、架空のイラストなど、個人を特定できない画像を使用してください。メッセージでアバター画像を使用した後は、画像の変更や削除はできません。

テキスト

最も単純なメッセージはテキストでできています。テキスト メッセージは、視覚、複雑な操作、またはレスポンスなしで情報を伝えるのに最適です。

例

次のコードは、単純なテキスト メッセージを送信します。リファレンス情報については、conversations.messages.create をご覧ください。

リッチテキスト

注: この機能はメッセージ専用です。ウェルカム メッセージ、返信の候補、おすすめのアクション、リッチカードではサポートされていません。

containsRichText が true に設定されたテキスト メッセージには、基本的なマークダウン形式を含めることができます。ハイパーリンクを追加したり、テキストを太字や斜体にしたりできます。有効な例を次の表に示します。

形式	文字数	書式なしテキスト	レンダリングされたテキスト
太字	**	**Some text**	一部のテキスト
イタリック体	*	*Some text*	一部のテキスト
Hyperlink	[]()	[Click here](https://www.example.com)	こちらをクリック
改行	\n	Line one\nLine two	1 行目 2 行目

書式は、次の規則にも従う必要があります。

• すべてのリンクは https:// または http:// で始まる必要があります
• さまざまな種類の書式をネストすることもできますが、それ以外は重複しないようにできます。
• \n による改行はメッセージの任意の場所に許可されますが、メッセージの末尾の改行は表示されません。
• 通常、予約文字（*、\、[、]）を表示するには、それらの文字の前にバックスラッシュ文字（\）を付ける必要があります。

無効な形式のメッセージは、無効なマークダウンに関するエラー メッセージで送信に失敗します。上記のルールに基づいて、より有効な例と無効な例を次の表に示します。

書式なしテキスト	有効性	レンダリングされたテキスト
[Click here](www.example.com)	無効。リンクが http:// または https:// で始まっていない	レンダリングされません。
[**Click here**](https://www.example.com)	有効です。ネストが許可されています。	こちらをクリック
**This is [not** valid](https://www.example.com)	無効。書式を重複させることはできません。	レンダリングされません。
** Some bold text **	無効。** 内で末尾に空白は使用できません。	レンダリングされません。
Citation below\*	有効です。* 文字はエスケープされます。	以下に引用*

注: 一部のスクリーン リーダーは、同じメール内の複数のリンクを読み取れません。1 つのメッセージに複数のリンクを追加しないでください。

推奨される措置

推奨アクションは、デバイスのネイティブ機能を利用して、ユーザーを会話に導くものです。ユーザーがアクションの候補をタップすると、エージェントはアクションのテキストとポストバック データを含むメッセージを受信します。

推奨されるアクションの最大文字数は 25 文字、メッセージには最大 13 文字です。

注意: エージェントは、推奨されるアクションのみに頼ってユーザーの行動をトリガーしないでください。ユーザーが古いバージョンのクライアントを使用している場合、そのクライアントは提案されたアクションを表示できない可能性があります。

書式設定と値のオプションについては、conversations.messages.create と SuggestedAction をご覧ください。

URL を開くアクション

「URL を開く」アクションでは、エージェントがユーザーが開く URL を提案します。アプリが URL のデフォルト ハンドラとして登録されている場合は、代わりにアプリが開き、アクションのアイコンがアプリのアイコンになります。オープン URL アクションは、HTTP プロトコルと HTTPS プロトコルの URL のみをサポートします。他のプロトコル（mailto など）はサポートされていません。

次のコードは、「URL を開く」アクションでテキストを送信します。書式設定と値のオプションについては、OpenUrlAction をご覧ください。

ライブ対応のエージェント リクエストの提案

ライブ対応のエージェント リクエストの提案を使用すると、複雑なやり取り中に、または自動化でユーザー リクエストを処理できない場合に、人間の担当者とやり取りするようにユーザーを導くことができます。

注: ライブ対応のエージェント リクエストの候補を送信するには、エージェントの BOT と HUMAN の両方のメッセージ機能を指定する必要があります。メッセージングの可用性を設定するをご覧ください。

ユーザーは、会話の途中でオーバーフロー メニューからライブ対応のエージェントをリクエストできます。この提案により、エージェントは、会話のコンテキストに基づいて人間の担当者とのインタラクションをプログラムで提案できます。エージェントは、ライブ対応のエージェント リクエストの提案を送信しなくても、ライブ対応のエージェントがリクエストしたイベントに常に応答できる状態になっている必要があります。

ユーザーがライブ対応のエージェント リクエストの提案をタップすると、ライブ対応のエージェントがリクエストしたイベントがトリガーされます。

リッチカード

関連する情報、メディア、候補のまとまりを送信する必要がある場合は、リッチカードを送信してください。リッチカードを使用すると、エージェントは単一のメッセージで複数の単位の情報を送信できます。

リッチカードには次の項目を含めることができます。

• メディア（JPG、JPEG、PNG、最大 5 MB）
• メディアのサムネイル（JPG、JPEG、PNG、最大 25 KB）
• タイトル（最大半角 200 文字（全角 100 文字））
• 説明文（最大半角 2,000 文字（全角 1,000 文字））
• 返信文の候補と操作の候補のリスト（最大 4 個）

リッチカードにはリストされた項目の一部またはすべてを含めることができますが、カードを有効にするにはメディアまたはタイトルを少なくとも 1 つ含める必要があります。リッチカードには、アクションの候補と返信の候補を 4 つまで含めることができます。

エージェントは、複数のリッチカードをリッチカード カルーセルにまとめて送信できます。

例

次のコードは、画像と返信の候補を含むリッチカードを送信します。形式と値のオプションについては、conversations.messages.create と RichCard をご覧ください。

リッチカード カルーセル

ユーザーに複数の選択肢を提示する必要がある場合は、リッチカード カルーセルを使用します。カルーセルは複数のリッチカードをつなぎ合わせ、ユーザーがアイテムを比較して個別に対応できるようにします。

カルーセルには、2 ～ 10 枚のリッチカードを含めることができます。カルーセル内のリッチカードは、コンテンツと高さに関する一般的なリッチカードの要件を満たす必要があります。

例
