DWS Viewer API
DWS Viewer API enables integration of document viewing, annotation, editing tools, and PDF form filling in your web app without maintaining viewer infrastructure. Use it with DWS-managed documents you upload to Nutrient infrastructure, or with app-provided documents your browser app passes directly to Nutrient Web SDK.
- DWS Viewer API is an optional SaaS component for Nutrient Web SDK. It provides authorization, usage tracking, and managed document workflows without requiring you to run Document Engine yourself.
- DWS Viewer API provides the Web SDK license entitlement in server-backed and standalone modes, so no separate Web SDK license is required for DWS Viewer API integrations. Server-backed integrations load Web SDK with a session token. Standalone integrations can use a session token or a publishable API key, which Web SDK exchanges for a temporary entitlement.
- DWS Viewer API doesn’t replace every Web SDK component. Digital signatures aren’t supported in DWS Viewer API yet, and capabilities such as measurement tools and document comparison are Web SDK features. Verify feature availability for your operational mode when planning an integration.
