OCR Document Understanding SDK-OCR(OCR)-阿里云帮助中心

This topic explains how to use the SDKs for multiple programming languages.

SDK introduction

The OCR Document Understanding SDK wraps all APIs from the 2022-12-29 version. It uses an access key (AccessKey) for authentication and includes features like automatic signing. This simplifies calling different custom models through the API. Alibaba Cloud Developer hosts SDKs for popular programming languages, providing repository URLs, installation commands, and release notes. For more information, see Developer Center. To obtain an AccessKey, see Obtain an AccessKey.

The OCR Document Understanding SDK supports popular programming languages, including Java, Node.js, Python, C++, C#, Go, and PHP. Follow the SDK quick start to get started, and use the SDK usage and debugging guide to make API calls. The guide also includes a demo project to help you quickly build an OCR Document Understanding application.
