第三方會議總覽
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
建立或編輯 Google 日曆活動時，使用者可以選擇快速建立 Google Meet 會議，並將其與活動建立關聯。新增後，活動參與者只要按一下滑鼠，即可輕鬆加入相關的環聊。
不過，如果使用者想使用第三方會議服務 (例如 WebEx) 而非 Google Meet，程序會比較複雜。通常使用者必須在 Google 日曆以外的地方建立會議，然後將會議代碼複製到日曆活動說明中。活動出席者必須按照特定步驟，使用提供的代碼加入會議。
Google Workspace 外掛程式可協助使用者避免這種複雜情況。您可以建構 Google Workspace 外掛程式，透過第三方會議解決方案擴充 Google 日曆功能。每新增一個會議解決方案，日曆活動就會新增一個會議選項，讓使用者直接透過 Google 日曆建立及加入這些會議。
如果您是會議服務供應商，可以建立 Google Workspace 外掛程式，定義 Google 日曆與您產品之間的連結。接著，您可以在 Google Workspace Marketplace 中發布外掛程式，供使用者和管理員探索及安裝。
會議解決方案
會議解決方案代表使用者可加入的第三方會議類型。建立或編輯 Google 日曆活動時，使用者可以選擇這些解決方案做為會議選項。
外掛程式可定義的會議解決方案範例如下：
- 標準視訊會議
- 純音訊會議
- 個人會議
- 公開串流播放的會議
第三方服務提供的任何類型會議都可以有相關聯的解決方案，而解決方案集合可以綁定在單一 Google Workspace 外掛程式中。
會議解決方案的運作方式
將會議解決方案新增至 Google Workspace 外掛程式時，不需要為該解決方案提供詳細的 UI。也就是說，使用者建立或編輯 Google 日曆活動時，只要安裝了 Google Workspace 外掛程式，系統就會將外掛程式中定義的解決方案顯示為會議選項。
使用者選取會議解決方案後，外掛程式會使用 API 連線至第三方會議系統，並建立會議，然後在會議和 Google 日曆活動之間同步處理資料。如果日後更新或刪除活動，外掛程式會偵測到這項變更，並在會議系統中進行相應的更新。將會議附加到活動後，與會者就能透過 Google 日曆加入會議。
外掛程式可以選擇提供設定頁面，讓使用者控管特定會議行為。
會議資料
為 Google 日曆提供會議解決方案的 Google Workspace 外掛程式需要特定資訊 (會議資料)，才能讓使用者加入第三方會議。在外掛程式中定義會議解決方案時，請指定 onCreateFunction，該物件會建構並傳回 ConferenceData 物件。ConferenceData 物件必須包含 Google 日曆所需的所有會議資料，或是描述與第三方會議系統通訊時發生錯誤的 ConferenceError 物件。
下表說明外掛程式可使用的各類型會議資料，並列出代表這些資料的 ConferenceData 服務物件。外掛程式使用的每個
ConferenceData
物件都必須標示所有「必要」元素：
| 元件 |
類型 |
說明 |
| 會議錯誤 |
ConferenceError |
如果發生錯誤，則為必要欄位，此時不需要提供其他資料。如果增益集嘗試連線至會議系統時發生問題，請使用這項功能回報。 |
| 會議 ID |
string |
如果不是錯誤，則為必要欄位。
使用這個 ID 在第三方會議系統中識別會議。 |
| 會議參數 |
ConferenceParameter[] |
使用這些鍵/值組合，將任何系統專屬資訊傳遞至第三方會議系統，以及從該系統傳遞資訊。舉例來說，系統可能需要會議管理員的電子郵件地址或會議金鑰。 |
| 會議記錄 |
string |
使用這項功能在會議中附加文字通知。通常用於為會議管理員新增操作說明或法律聲明。 |
| 進入點 |
EntryPoint[] |
如果不是錯誤，則為必填欄位，且至少須定義一個 EntryPoint。
使用 EntryPoint 說明加入會議的具體方式 (例如透過電話、視訊或 SIP)。每個進入點都需要 URI 和
EntryPointType。 |

Typically this\nrequires the user to create the conference outside of Google Calendar and then\ncopy a conference code into the Calendar event description. Event attendees\nthen must follow a specific set of steps to enter the conference using the code\nprovided.\n\nGoogle Workspace add-ons can help users avoid this\ncomplexity. You can build a Google Workspace add-on\nthat extends Google Calendar with third-party\n[*conference solutions*](#conference_solutions).\nEach added conference solution adds a new conferencing option for Calendar\nevents, allowing users to create and join those conferences directly from\nGoogle Calendar.\n\nIf you are a conference provider, you can create a\nGoogle Workspace add-on to define a connection between\nGoogle Calendar and your product. You can then publish the add-on in the\n[Google Workspace Marketplace](https://workspace.google.com/marketplace/),\nwhere users and administrators can discover and install it.\n\nConference solutions\n--------------------\n\nA conference solution represents a type of third-party conference that users\ncan join. Each solution is shown as a conferencing option a user can choose\nwhen creating or editing a Google Calendar event.\n\nExamples of conference solutions an add-on might define include the following:\n\n- a standard video conference\n- an audio-only conference\n- a personal conference\n- a publicly streamed conference\n\nAny type of conference that the third-party service provides can have\nan associated solution, and collections of solutions can be bundled together\nin a single Google Workspace add-on.\n\n### How conference solutions work\n\nWhen a conference solution is added to a\nGoogle Workspace add-on, there is no need\nto provide a detailed UI for it. Instead, whenever a user creates or edits a\nGoogle Calendar event, any solutions defined in the\nGoogle Workspace add-ons the user\nhas installed appear as conferencing options.\n\nWhen a user selects a conference solution, the add-on connects to the\nthird-party conferencing system using its API and creates the conference,\nsyncing data between the conference and the Google Calendar event. If the\nevent is later updated or deleted, the add-on detects this and makes the\ncorresponding updates on the conferencing system. Once a conference is attached\nto an event, attendees can join the conference from Google Calendar.\n\nOptionally, the add-on can provide a settings page to allow users to control\nspecific conferencing behavior.\n\nConference data\n---------------\n\nGoogle Workspace add-ons that provide conference\nsolutions to Google Calendarrequire specific information---*conference\ndata* ---in order to let users join third-party conferences. When you define\na conference solution in your add-on, you specify an\n[`onCreateFunction`](/apps-script/manifest/calendar-addons#ConferenceSolution.FIELDS.onCreateFunction)\nthat builds and returns a\n[`ConferenceData`](/apps-script/reference/conference-data/conference-data)\nobject. The `ConferenceData` object must contain either all the conference data\nGoogle Calendar needs, or a\n[`ConferenceError`](/apps-script/reference/conference-data/conference-error)\nobject that describes an error that occurred when communicating with the\nthird-party conferencing system.\n\nThe table below describes each type of conference data your add-on can use and\nlists the [ConferenceData service](/apps-script/reference/conference-data)\nobject that represents it. Each\n[`ConferenceData`](/apps-script/reference/conference-data/conference-data)\nobject your add-on uses must have all elements marked as **Required**:\n\n| Component | Type | Description |\n|-----------------------|-------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| Conference errors | ` `[ConferenceError](/apps-script/reference/conference-data/conference-error) | **Required if an error occurred, in which case no other data is needed.** Use this to report a problem that happened when the add-on tried to connect to the conferencing system. |\n| Conference ID | `string` | **Required if not an error.** Use this ID to identify the conference within the third-party conferencing system. |\n| Conference parameters | ` `[ConferenceParameter](/apps-script/reference/conference-data/conference-parameter)`[]` | Use these key-value pairs to pass any system-specific information to and from the third-party conferencing system. For example, the system may require the email of the conference moderator, or a meeting key. |\n| Conference notes | `string` | Use this to append a text notice to the conference. Typically you use these to add instructions for conference administrators or legal notices. |\n| Entry points | [EntryPoint](/apps-script/reference/conference-data/entry-point)`[]` | **Required if not an error, in which case at least one `EntryPoint` must be defined.** Use `EntryPoint`s to describe a specific way to join the conference (for example, by phone, video, or SIP). Each entry point requires a URI and an [EntryPointType](/apps-script/reference/conference-data/entry-point-type). |\n\nFurther reading\n---------------\n\nThe following documentation can help you learn more:\n\n- **Build a Google Workspace add-on with conference solutions.**\n [Build conference add-ons](/workspace/add-ons/calendar/conferencing/build-conference-addons)\n provides an overview of the steps required to build a\n Google Workspace add-on that implements third-party\n conference solutions.\n\n- **Get a closer look.** View the\n [source code of a conferencing Google Workspace add-on example](/workspace/add-ons/samples/conferencing-sample).\n\n- **Learn more about what Apps Script can do.** Review the\n [Google Apps Script documentation](/apps-script).\n\n- **Wondering what other developers have built?** Visit the\n [Google Workspace Marketplace for Google Calendar](https://workspace.google.com/marketplace/category/works-with-calendar)."]]
