更新卡券类和卡券对象

及时更新卡券是与客户互动的重要方式，营造积极的体验

有两个资源可以更新：TransitClass 和 TransitObject。

最佳做法

以下列表包含在更新公交卡类和对象：

如果您要更新整个类或对象，请发送 update 请求。如果您要更新类或对象中的少量字段，请将 patch 请求。
当您发出 update 请求时，整个对象或类都会更新。这意味着，请求中未包含的所有字段都将被清除。在发送 update 请求之前，我们建议您先将 GET 请求发送到确保您使用的是最新版本字段。
发出 patch 请求时，只有修补后的字段已更新。在发送 patch 请求之前，不妨考虑选择性地发送 GET 请求，用于将您所做的更改与最新版本进行比较。
在发出更新数组的 patch 请求时，原始数组为替换为请求正文中包含的 ID。您不能修改元素。
在某些情况下，您可能不知道何时或何时会触发更改更新。建议您定期为以下时间范围的 update 或 patch 请求安排时间：所有类和对象

更新卡券类

使用 Google 电子钱包商家控制台

您可以直接在 Google Pay 和钱包控制台。

前往控制台
选择 Google Wallet API
选择要修改的课程
选择修改
更新类属性
选择保存

保存更改后，系统会针对您公交用户。

使用 Google Wallet API

更新 TransitClass 会影响所有已预配的用户使用此类访问公交卡。例如，要更新您的公交卡，请向以下地址提交 update 或 patch 请求：在以下任一端点上访问 Google Wallet API。resourceId 值为类 ID (ISSUER_ID.CLASS_SUFFIX)。

# Update
PUT https://walletobjects.googleapis.com/walletobjects/v1/transitclass/{resourceId}

# Patch
PATCH https://walletobjects.googleapis.com/walletobjects/v1/transitclass/{resourceId}
