API 调用

与使用 Document Understanding 或智能 OCR 活动处理文档类似，您可以使用 API 通过以下四个主要阶段来处理文档：数字化、分类、提取和验证。

当您想要使用 API 创建 Document Understanding 自动化时，请按照以下步骤操作：

1. Digitize documents. Visit the Digitization APIs to check the APIs available for digitizing.
2. Classify documents. Visit the Classification Service to learn how to use the classification service.
3. Validate the classification results. Visit Validation of a Classification Result for more information.
4. Extract documents using the Extraction Service. Visit the Extraction Service to learn how to use the extraction service.
5. Validate the extraction information. Visit Validation of an Extraction Result to learn how to validate parts of the documents you extracted.
