如何使用Java FB Business SDK获取Facebook广告帐户的转换？

<dependency>
    <groupId>com.facebook</groupId>
    <artifactId>facebook-java-business-sdk</artifactId>
    <version>VERSION</version>
</dependency>

import com.facebook.ads.sdk.APIContext;

String appId = "YOUR_APP_ID";
String appSecret = "YOUR_APP_SECRET";
APIContext context = new APIContext(appId, appSecret);

import com.facebook.ads.sdk.*;

String accountId = "YOUR_AD_ACCOUNT_ID";
AdsInsights insights = new AdAccount(accountId, context).getInsights()
        .setLevel(AdsInsights.EnumLevel.VALUE_ACCOUNT)
        .setTimeRange("{\"since\":\"2022-01-01\",\"until\":\"2022-01-31\"}")
        .setFields("actions")
        .execute();

List<AdsInsights> insightsList = insights.get().getData();
for (AdsInsights insight : insightsList) {
    System.out.println("Actions: " + insight.getFieldActions());
}
