本指南将详细说明如何使用 Campaign Manager 360 API Conversions 服务修改转化事件。在继续阅读本文之前，建议您先查看概览，简要了解一下线下转化并让自己熟悉本指南中要讨论的几个概念。
准备工作
通过此修改工作流程，您可以修改现有在线和线下转化事件的 quantity 和 value。为此，您需要提供相应的值来唯一标识要修改的转化事件。根据您要修改的转化事件的类型，您可以使用不同方式获取这些值：
标识在线转化事件所需的值可通过数据传输获得。
标识线下转化事件所需的值会在成功完成的
batchinsert请求的ConversionsBatchInsertResponse中返回。
在您成功修改任一类型的转化后，ConversionsBatchUpdateResponse 将包含执行后续修改所需的值。
配置转化资源
修改工作流程的第一步涉及创建一个或多个 Conversion 资源对象。
以下字段用于标识要修改的转化事件。这些字段为必填字段，并且必须与现有转化事件完全匹配。
| 字段 | 说明 |
|---|---|
|
生成相应转化事件的经过加密的用户 ID、Google 点击 ID、展示广告点击 ID、匹配 ID 或移动设备 ID。 |
floodlightActivityId |
转化事件归因到的 Floodlight 活动。 |
floodlightConfigurationId |
所指定的活动使用的 Floodlight 配置。 |
ordinal |
与转化事件相关联的重复信息删除标识符。 |
timestampMicros |
相应转化的时间戳（自 Unix 新纪元至今的时间，以微秒为单位）。 |
下面列出了可修改的字段。
这些字段为必填字段，您提供的值将覆盖要修改的转化事件中任何预先存在的值。
| 字段 | 说明 |
|---|---|
quantity |
与相应转化事件相关联的项数。 |
value |
相应转化事件产生的收入金额。 |
这些字段是可选字段。如果未设置，该值将保持不变。
| 字段 | 说明 |
|---|---|
customVariables |
转化的自定义 Floodlight 变量。如果变量已设置，则会更新或插入该值。如果未设置，变量的值保持不变。 |
参考文档中提到的所有其他字段均不受支持，并且无法修改。在修改请求中添加不受支持的字段会导致出现错误。如果要修改的转化事件中有任何不受支持的字段包含预先存在的值，系统会自动保留这些值。
以下示例展示了如何创建一个简单的 Conversion 资源对象以进行修改：
// Find the Floodlight configuration ID based on the provided activity ID.
FloodlightActivity floodlightActivity =
service.FloodlightActivities.Get(profileId, floodlightActivityId).Execute();
long floodlightConfigurationId = (long) floodlightActivity.FloodlightConfigurationId;
// Construct the conversion object with values that identify the conversion to update.
Conversion conversion = new Conversion();
conversion.EncryptedUserId = conversionUserId;
conversion.FloodlightActivityId = floodlightActivityId;
conversion.FloodlightConfigurationId = floodlightConfigurationId;
conversion.Ordinal = conversionOrdinal;
conversion.TimestampMicros = conversionTimestamp;
// Set the fields to be updated. These fields are required; to preserve a value from the
// existing conversion, it must be copied over manually.
conversion.Quantity = newQuantity;
conversion.Value = newValue;
// Create a conversion object populated with values that identify the conversion to update.
Conversion conversion = new Conversion();
conversion.setEncryptedUserId(encryptedUserId);
conversion.setFloodlightActivityId(floodlightActivityId);
conversion.setFloodlightConfigurationId(floodlightConfigurationId);
conversion.setOrdinal(ordinal);
conversion.setTimestampMicros(timestampMicros);
// Set the fields to be updated. These fields are required; to preserve a value from the
// existing conversion, it must be copied over manually.
conversion.setQuantity(newQuantity);
conversion.setValue(newValue);
// Find Floodlight configuration ID based on provided activity ID.
$activity = $this->service->floodlightActivities->get(
$values['user_profile_id'],
$values['floodlight_activity_id']
);
$floodlightConfigId = $activity->getFloodlightConfigurationId();
// Create a conversion object with values that identify the conversion to
// update.
$conversion = new Google_Service_Dfareporting_Conversion();
$conversion->setEncryptedUserId($values['encrypted_user_id']);
$conversion->setFloodlightActivityId($values['floodlight_activity_id']);
$conversion->setFloodlightConfigurationId($floodlightConfigId);
$conversion->setOrdinal($values['ordinal']);
$conversion->setTimestampMicros($values['timestamp']);
// Set the fields to be updated. These fields are required; to preserve a
// value from the existing conversion, it must be copied over manually.
$conversion->setQuantity($values['new_quantity']);
$conversion->setValue($values['new_value']);
# Construct the conversion object with values that identify the conversion
# to update.
conversion = {
'encryptedUserId': encrypted_user_id,
'floodlightActivityId': floodlight_activity_id,
'floodlightConfigurationId': floodlight_config_id,
'ordinal': ordinal,
'timestampMicros': timestamp
}
# Set the fields to be updated. These fields are required; to preserve a
# value from the existing conversion, it must be copied over manually.
conversion['quantity'] = new_quantity
conversion['value'] = new_value
# Look up the Floodlight configuration ID based on activity ID.
floodlight_activity = service.get_floodlight_activity(profile_id,
existing_conversion[:floodlight_activity_id])
floodlight_config_id = floodlight_activity.floodlight_configuration_id
# Construct the conversion with values that identify the conversion to
# update.
conversion = DfareportingUtils::API_NAMESPACE::Conversion.new(
encrypted_user_id: existing_conversion[:encrypted_user_id],
floodlight_activity_id: existing_conversion[:floodlight_activity_id],
floodlight_configuration_id: floodlight_config_id,
ordinal: existing_conversion[:ordinal],
timestamp_micros: existing_conversion[:timestamp]
)
# Set the fields to be updated. These fields are required; to preserve a
# value from the existing conversion, it must be copied over manually.
conversion.quantity = new_quantity
conversion.value = new_value
指定加密信息
如果要修改的转化事件与经过加密的用户 ID 相关联，您便需要在修改请求中提供与此类用户 ID 的加密方式相关的详细信息。如需了解详情，请参阅上传转化指南。
必要时，请创建一个用于指定这些值的 EncryptionInfo 对象，这是修改工作流程的第二步：
// Create the encryption info.
EncryptionInfo encryptionInfo = new EncryptionInfo();
encryptionInfo.EncryptionEntityId = encryptionEntityId;
encryptionInfo.EncryptionEntityType = encryptionEntityType;
encryptionInfo.EncryptionSource = encryptionSource;
// Create the encryption info.
EncryptionInfo encryptionInfo = new EncryptionInfo();
encryptionInfo.setEncryptionEntityId(encryptionEntityId);
encryptionInfo.setEncryptionEntityType(encryptionEntityType);
encryptionInfo.setEncryptionSource(encryptionSource);
$encryptionInfo = new Google_Service_Dfareporting_EncryptionInfo();
$encryptionInfo->setEncryptionEntityId($values['encryption_entity_id']);
$encryptionInfo->setEncryptionEntityType($values['encryption_entity_type']);
$encryptionInfo->setEncryptionSource($values['encryption_source']);
# Construct the encryption info.
encryption_info = {
'encryptionEntityId': encryption_entity_id,
'encryptionEntityType': encryption_entity_type,
'encryptionSource': encryption_source
}
# Construct the encryption info.
encryption_info = DfareportingUtils::API_NAMESPACE::EncryptionInfo.new(
encryption_entity_id: encryption[:entity_id],
encryption_entity_type: encryption[:entity_type],
encryption_source: encryption[:source]
)
生成更新请求
该流程的最后一步是通过调用 batchupdate 修改转化事件。此方法会接受一个 ConversionsBatchUpdateRequest 对象，而该对象会将要修改的一组转化事件与相关加密信息整合到一起（如有必要）：
// Insert the conversion.
ConversionsBatchUpdateRequest request = new ConversionsBatchUpdateRequest();
request.Conversions = new List<Conversion>() { conversion };
request.EncryptionInfo = encryptionInfo;
ConversionsBatchUpdateResponse response =
service.Conversions.Batchupdate(request, profileId).Execute();
ConversionsBatchUpdateRequest request = new ConversionsBatchUpdateRequest();
request.setConversions(ImmutableList.of(conversion));
request.setEncryptionInfo(encryptionInfo);
ConversionsBatchUpdateResponse response = reporting.conversions()
.batchupdate(profileId, request).execute();
$batch = new Google_Service_Dfareporting_ConversionsBatchUpdateRequest();
$batch->setConversions([$conversion]);
$batch->setEncryptionInfo($encryptionInfo);
$result = $this->service->conversions->batchupdate(
$values['user_profile_id'],
$batch
);
# Update the conversion.
request_body = {
'conversions': [conversion],
'encryptionInfo': encryption_info
}
request = service.conversions().batchupdate(
profileId=profile_id, body=request_body)
response = request.execute()
# Construct the batch update request.
batch_update_request =
DfareportingUtils::API_NAMESPACE::ConversionsBatchUpdateRequest.new(
conversions: [conversion],
encryption_info: encryption_info
)
# Update the conversion.
result = service.batchupdate_conversion(profile_id, batch_update_request)
请注意，Campaign Manager 360 会试着尽力修改您的请求中的每一个转化事件，而不是将相应的批次作为一个整体进行更新。即使该批次中有些转化事件更新失败，其他转化事件也仍可能更新成功。因此，建议您检查返回的 ConversionsBatchUpdateResponse，以确定每个转化事件的状态：
// Handle the batchinsert response.
if (!response.HasFailures.Value) {
Console.WriteLine("Successfully updated conversion for encrypted user ID {0}.",
conversionUserId);
} else {
Console.WriteLine("Error(s) updating conversion for encrypted user ID {0}:",
conversionUserId);
ConversionStatus status = response.Status[0];
foreach(ConversionError error in status.Errors) {
Console.WriteLine("\t[{0}]: {1}", error.Code, error.Message);
}
}
if (!response.getHasFailures()) {
System.out.printf("Successfully updated conversion for encrypted user ID %s.%n",
encryptedUserId);
} else {
System.out.printf("Error(s) updating conversion for encrypted user ID %s:%n",
encryptedUserId);
// Retrieve the conversion status and report any errors found. If multiple conversions
// were included in the original request, the response would contain a status for each.
ConversionStatus status = response.getStatus().get(0);
for (ConversionError error : status.getErrors()) {
System.out.printf("\t[%s]: %s.%n", error.getCode(), error.getMessage());
}
}
if (!$result->getHasFailures()) {
printf(
'Successfully updated conversion for encrypted user ID %s.',
$values['encrypted_user_id']
);
} else {
printf(
'Error(s) updating conversion for encrypted user ID %s:<br><br>',
$values['encrypted_user_id']
);
$status = $result->getStatus()[0];
foreach ($status->getErrors() as $error) {
printf('[%s] %s<br>', $error->getCode(), $error->getMessage());
}
}
if not response['hasFailures']:
print('Successfully updated conversion for encrypted user ID %s.' %
encrypted_user_id)
else:
print('Error(s) updating conversion for encrypted user ID %s.' %
encrypted_user_id)
status = response['status'][0]
for error in status['errors']:
print '\t[%s]: %s' % (error['code'], error['message'])
if result.has_failures
puts format('Error(s) updating conversion for encrypted user ID %s.',
existing_conversion[:encrypted_user_id])
status = result.status[0]
status.errors.each do |error|
puts format("\t[%s]: %s", error.code, error.message)
end
else
puts format('Successfully updated conversion for encrypted user ID %s.',
existing_conversion[:encrypted_user_id])
end
如上所示，对于原始请求中包含的每个转化事件，相应响应的 status 字段中都会有一个 ConversionStatus 对象与之对应。如果您只想了解未能成功更新的转化事件，可使用 hasFailures 字段来快速确定所提供的批量转化事件中是否有任何转化事件更新失败。
