Foxit Document Workflow APIs vs. AiDO for Developers

Foxit provides a powerful portfolio of cloud-native APIs built to help organizations streamline, secure, and scale document-centric workflows. Leveraging flexible REST-based architecture, Foxit APIs enable developers to integrate document creation, conversion, extraction, signing, and viewing capabilities directly into their applications—driving greater efficiency and reducing operational complexity. The Foxit PDF Services API supports high-volume PDF processing tasks such as conversion, extraction, optimization, and redaction. The Document Generation API automates the creation of customized PDFs and DOCX files using dynamic templates and real-time data sources. The Foxit eSign API embeds compliant, legally binding eSignature workflows with advanced audit and tracking features. The PDF Embed API enables fully customizable in-app PDF viewing with support for annotations, forms, and secure access controls. Together, Foxit APIs deliver a secure, scalable foundation for end-to-end document automation and digital workflow transformation.

AiDO for Developers helps product and engineering teams add document features to their software without building an in-house PDF team. Embed PDF viewing, editing, conversion, OCR, e-signatures and AI data extraction through one SDK and API from a single vendor, so your developers can focus on your core product. The problem: document features often turn into a 3-6 month detour, several vendors for OCR, conversion and signing, and engineers maintaining PDF edge cases for years. AiDO for Developers replaces that with one integration that Avanquest maintains, backed by 20+ years of production use. Four products, each available separately: PDF API: cloud REST API to convert, merge, split, compress, OCR, watermark, protect and sign documents, plus AI data extraction. PDF SDK: native SDK for Windows and Linux (C++ and C#/.NET). PDF Web SDK: white-label PDF experiences in your web app, with theming, annotation, redaction, signing and forms. WebApp: ready-to-use web component for viewing, annotating and searching PDFs.
