本部分介绍如何发送商品目录的有时效性更新 实体提供给 Google。借助 Real-time Updates API,您可以推送更新和删除 您的沙盒或正式版广告资源中的实体。
此功能主要用于您无法预见的更新, 例如紧急封闭、从菜单中移除商品或更新价格 必须快速反映在 Google 界面中。如果您更改了 不需要立即体现,您可以使用 批量注入。实时更新以 不超过五分钟。
前提条件
在实现实时更新之前,必须满足以下要求:
- Maps Booking API 已启用:
<ph type="x-smartling-placeholder">
- </ph>
- 在 GCP 中,转到 API 和服务 >媒体库
- 搜索“Google Maps Booking API”
- 找到沙盒实例(“Google Maps Booking API(开发版”),然后点击 启用
- 找到正式版实例(“Google Maps Booking API”),然后点击
启用
- 系统将创建一个具有 GCP 项目的 Editor 角色的服务账号。对于 请参见 账号设置。
- 托管和提取生产或沙盒数据 Feed。如需了解更多详情, 请参阅批量提取。
- 对于 API 身份验证,建议安装 Google 客户端库 选择。使用“https://www.googleapis.com/auth/mapsbooking”作为 OAuth 范围。下面提供的代码示例使用这些库。否则 则需要按照说明,手动处理令牌交换, 使用 OAuth 2.0 访问 Google API。
概览
实时更新 API 支持两种类型的操作。第一项操作是 upsert,用于更新现有实体。通过 第二个操作是删除,用于从您的广告资源中移除实体。两者都有 操作针对请求正文中列出的一系列实体执行。您 可以在一次 API 调用中对多达 1,000 个实体进行更新。该 API 接受 所有传入的请求,并将其放入队列中以便进一步处理。 因此,系统会异步处理 RTU 请求。
实时更新 API 在两种环境中运行:沙盒环境和生产环境。 沙盒环境用于测试 API 请求 环境,以便更新对端到端订购用户可见的内容。主机名 两种环境:
- 沙盒 -
partnerdev-mapsbooking.googleapis.com
- 正式版 -
mapsbooking.googleapis.com
端点
实时更新 API 公开了两个端点来处理传入请求 :
- UPSERT -
/v1alpha/inventory/partners/
PARTNER_ID/feeds/owg.v2/record:batchPush
- 删除 -
/v1alpha/inventory/partners/
PARTNER_ID/feeds/owg.v2/record:batchDelete
参数 PARTNER_ID 可以在 Actions Center 中找到 在账号和用户页面上显示为合作伙伴 ID,如 屏幕截图。
![合作伙伴门户上的合作伙伴 ID](https://developers.google.cn/static/actions-center/verticals/ordering/images/rtu-partnerid.png?authuser=1&hl=ca)
以 10000001 作为 PARTNER_ID 的值, 如上面的屏幕截图所示,在沙盒中发送 API 请求的完整网址, 如下面的示例所示。
# Sandbox UPSERT
https://partnerdev-mapsbooking.googleapis.com/v1alpha/inventory/partners/10000001/feeds/owg.v2/record:batchPush
# Sandbox DELETE
https://partnerdev-mapsbooking.googleapis.com/v1alpha/inventory/partners/10000001/feeds/owg.v2/record:batchDelete
# Production UPSERT

# Production DELETE
https://mapsbooking.googleapis.com/v1alpha/inventory/partners/10000001/feeds/owg.v2/record:batchDelete
更新实体
如需更新清单中的实体,请使用 UPSERT 端点, 并发送 HTTP POST 请求每个 POST 请求都必须包含 PARTNER_ID 参数以及包含 产品目录架构中列出的任何实体类型的结构化数据。
更新/插入请求载荷
请求正文是一个包含记录列表的 JSON 对象。每条记录
与要更新的实体相对应。它包含 data_record
字段
实体载荷是采用 Base64 编码的,并且 generation_timestamp
指示实体更新的时间:
{ "records": [ { "data_record":"BASE_64_ENCODED_ENTITY", "generation_timestamp":"UPDATE_TIMESTAMP" } ] }
在上述载荷中,替换以下内容:
BASE_64_ENCODED_ENTITY: 实体。解码后的实体 JSON 应该与 Feed 规范,例如:
{"@type":"MenuSection","name":"My Updated Menu Section","menuId":{"@id":"10824","displayOrder":1},"@id":"853705"}
UPDATE_TIMESTAMP:确保包含 在您的后端系统中生成了实体。此时间戳用于 确保商品目录更新按正确的顺序排列。如果未添加此字段 该时间设置为 Google 收到请求的时间。更新时
batchPush
请求指定实体,则generation_timestamp
字段是 用于实体版本控制。查看预期 关系型目录中时间值的格式 架构。
每个实时更新请求都必须满足以下条件:
- 载荷正文的大小不得超过 5 MB。与批处理作业相似, Feed,我们建议您删除空白,以适应更多数据。
- 一个
batchPush
请求中最多可以包含 1,000 个实体。
示例
示例 1:更新餐厅
假设您急需更新某家餐厅的电话号码。您的 update 包含整个餐馆的 JSON。
假设批量 Feed 如下所示:

示例 3:更新菜单项的价格
假设您需要更改菜单项的价格。
假设批量 Feed 如下所示:
{ "@type": "MenuItemOffer", "@id": "menuitemoffer6680262", "sku": "offer-cola", "menuItemId": "menuitem896532", "price": 2, "priceCurrency": "USD" }
那么,通过 POST 进行的实时更新将如下所示:

添加实体
请勿使用实时更新来添加新实体,因为这可能会导致数据不一致。您可以改为使用 此过程(如批量提取中所述)。
删除实体
如需从广告资源中删除实体,请使用 DELETE 命令 端点,以及发送 HTTP POST 请求。每个 POST 请求都必须 添加 PARTNER_ID 参数以及 JSON 载荷 包含您的广告资源中任何实体的标识符。
删除请求载荷
删除请求的正文的结构类似于
更新请求。
它还包含一个包含 data_record
和 delete_time
字段的记录列表:
{ "records": [ { "data_record":"BASE_64_ENCODED_REFERENCE", "delete_time": "DELETE_TIMESTAMP" } ] }
在上述载荷中,替换以下内容:
BASE_64_ENCODED_REFERENCE: 对要删除的实体的引用。一个引用仅包含 从实体类型和标识符获取,例如 对 MenuSection 的引用:
{"@type":"MenuSection","@id":"853705"}
DELETE_TIMESTAMP:确保包含 实体已删除。此时间戳用于 确定对广告资源应用删除操作的顺序。
一个 batchDelete
请求中最多可以包含 1,000 个实体。
示例
示例 1:移除两个 MenuItem
实体
要在单个 API 调用中移除两个菜单项,HTTP POST 请求应为 如下:
JSON
POST v1alpha/inventory/partners/PARTNER_ID/feeds/owg.v2/record:batchDelete Host: mapsbooking.googleapis.com Content-Type: application/json { "records": [ { "data_record": { "@type": "MenuItem", "@id": "item_1234" }, "delete_time": "2022-08-21T15:23:00.000Z" }, { "data_record": { "@type": "MenuItem", "@id": "item_5678" }, "delete_time": "2022-08-21T15:23:00.000Z" } ] }
Base64
使用 Base64 编码的载荷的相同示例。

示例 2:删除 Restaurant
实体
假设您想从批量 Feed 中删除某家餐馆。 您只能删除餐馆实体。请勿删除子实体,例如 服务和菜单,因为它们会被自动移除。
删除具有 ID 的餐馆实体的示例请求
https://www.provider.com/restaurant/12345
:
JSON
POST v1alpha/inventory/partners/PARTNER_ID/feeds/owg.v2/record:batchDelete Host: mapsbooking.googleapis.com Content-Type: application/json { "records": [ { "data_record": { "@type": "Restaurant", "@id": "https://www.provider.com/restaurant/12345" }, "delete_time": "2022-08-19T17:11:10.750Z" } ] }
Base64
使用 Base64 编码的载荷的相同示例。

验证和API 响应代码
在实时更新 API 调用中会执行两种类型的验证:
请求级 - 这些验证会检查载荷是否遵循 upsert 或 delete 架构,并且每个
data_record
都包含@id
和@type
字段。 这些检查是同步的,并且结果会在 API 中返回 响应正文。响应代码 200 和空 JSON 正文{}
表示 已通过验证,且请求中的实体已排队等待 处理。如果响应代码不是 200,则表示 验证失败,整个请求都被拒绝(包括 实体)。例如,如果data_record
缺少@type
时,系统将返回以下错误响应:{ "error": { "code": 400, "message": "Record:{\"@id\":\"2717/86853/DELIVERY\",\"applicableServiceType\":[\"DELIVERY\",\"TAKEOUT\"],\"menuId\":[{\"@id\":\"2717/DELIVERY\",\"displayOrder\":1},{\"@id\":\"2717/TAKEOUT\",\"displayOrder\":2}],\"name\":\"Salad\",\"offeredById\":[\"2717\"]} has following errors: \nThe entity type could not be extracted from the entity value.\n", "status": "INVALID_ARGUMENT", "details": [ { "@type": "type.googleapis.com/google.rpc.DebugInfo", "detail": "[ORIGINAL ERROR] generic::invalid_argument: Failed to parse one or more rtu records. Record:{\"@id\":\"2717/86853/DELIVERY\",\"applicableServiceType\":[\"DELIVERY\",\"TAKEOUT\"],\"menuId\":[{\"@id\":\"2717/DELIVERY\",\"displayOrder\":1},{\"@id\":\"2717/TAKEOUT\",\"displayOrder\":2}],\"name\":\"Salad\",\"offeredById\":[\"2717\"]} has following errors: \nThe entity type could not be extracted from the entity value.\n [google.rpc.error_details_ext] { message: \"Record:{\\\"@id\\\":\\\"2717/86853/DELIVERY\\\",\\\"applicableServiceType\\\":[\\\"DELIVERY\\\",\\\"TAKEOUT\\\"],\\\"menuId\\\":[{\\\"@id\\\":\\\"2717/DELIVERY\\\",\\\"displayOrder\\\":1},{\\\"@id\\\":\\\"2717/TAKEOUT\\\",\\\"displayOrder\\\":2}],\\\"name\\\":\\\"Salad\\\",\\\"offeredById\\\":[\\\"2717\\\"]} has following errors: \\nThe entity type could not be extracted from the entity value.\\n\" }" } ] } }
实体级 - 载荷中的每个实体都会根据 关系型架构。 在此验证阶段遇到的问题不会通过 API 报告 响应。它们仅在 RTU 报告 信息中心。
API 配额
实时 API 更新的配额为每 60 秒 1500 次请求,即 25 次请求 每秒请求数超出配额时,Google 会返回以下错误消息:
{ "error": { "code": 429, "message": "Insufficient tokens for quota ...", "status": "RESOURCE_EXHAUSTED", "details": [...] } }
如需解决该问题,请使用以指数方式增大的时间间隔再次尝试重新调用,直到成功为止。如果您经常用尽配额,请考虑添加更多实体 提交一个 API 请求。一次 API 调用最多可以包含 1,000 个实体。
代码示例
以下是一些示例,展示了如何在不同环境中使用实时更新 API 语言。这些示例使用 Google Auth 库,通过 服务账号密钥文件 账号设置。 如需了解替代解决方案,请参阅 针对“服务器到服务器”应用使用 OAuth 2.0。 请考虑使用生成客户端库中提供的架构,为广告资源和实时更新对象类型生成源代码。

使用场景
以下是实时更新、批量 Feed 更新、 以及 API 调用中的较高级别内容:
场景 | 要更新的实体 | 说明和效果 |
---|---|---|
停用服务 | Service |
由于不可预见的原因,您需要停用服务。 实时更新:在以下位置更新 完整 Feed:请务必根据完整 Feed 更新实体
将 |
特定商品缺货 | MenuItemOffer |
实时更新:发送封装 MenuItemOffer
具有 inventoryLevel 设置为 0 的实体。
MenuItem ,所有其他数据保持不变。 |
菜单项价格变动 | MenuItemOffer |
实时更新:发送封装 MenuItemOffer
将 price 设置为指定
MenuItem ,所有其他数据保持不变。 |
添加新的顶级实体 仅适用于 |
Menu 、Restaurant 、Service |
例如,您需要向餐厅添加新菜单。 完整 Feed:在数据 Feed 中添加实体,并等待批量提取。 |
永久删除顶级实体 仅适用于 |
Menu 、Restaurant 、Service |
实时更新:向 Google 发送 显式删除。 完整 Feed:务必先从完整 Feed 中移除实体,然后再 下次提取时,系统将重新添加该实体。 |
在特定Service 添加新的送货区域 |
ServiceArea |
批量 Feed:将相关 ServiceArea 实体及其所有
字段保持不变,就像您在完整 Feed 中一样,同时具有新的送货区域
在 polygon 、geoRadius 或 postalCode 内指定。 |
更新预计送达时间(Service ) |
ServiceHours |
批量供稿:发送ServiceHours 与
Feed,但其 leadTimeMin 已更新
。 |
更新Service 的运费 |
Fee |
批量供稿:发送完整递送Fee ,
“price ”已更新。 |
更新Service 的送货或外卖时间 |
ServiceHours |
批量供稿:发送ServiceHours 与
Feed,但其 opens 和 closes 属性已更新
。 |
Service (更改最低订单金额) |
Fee |
批量供稿:发送完整Fee
minPrice
已更新 |
永久删除 MenuItem |
Menu |
批量供稿:发送MenuItem 与
但 parentMenuSectionId 为空。
|
批量作业和实时更新的处理时间
通过批处理 Feed 更新或删除的实体会在 2 分钟内进行处理 而通过实时更新更新的实体将在 5 分钟。答 过时实体 将在 14 天后删除。
您可向 Google 发送以下信息:
- 每天多个批量作业,确保您的商品目录处于最新状态;或
- 每天一个批量作业和实时更新,让您的库存保持最新状态。
