通过DSS Rest API 获取Corporate Actions 数据的时候如何添加过滤条件
请问我在使用 Extractions/ExtractWithNotes API去获取一组instruments在某个时间段的Corporate Actions数据的时候，应该如何给ExtractionRequest添加过滤条件呢？比如我只想得到 "Capital Change Event Type" = 21 或者 80 的数据 （这里的21是股票分割的ID; 80是分红数据）

您好，您可以从 Rest API Reference Tree 页面找到每个extraction request所支持的参数列表。下面是一个示例
您可以直接在页面上设置不同参数的输入值，然后点击旁边的JSON Model页面查看JSON格式的request信息。要找到以上信息，您可以参考下面的两步
1）按照下图先找到ExtractionWithNotes
2) 在页面右侧下拉框任意选择您感兴趣的ExtractionRequest即可
