Composer Link Service is a Composer Advanced Feature that allows end-users to create and send documents through email. Composer solutions using Composer Link Service create a unique link for each document, making documents easily shareable and accessible. Word, Excel, and PowerPoint files sent with Composer Link Service are downloaded to the browser tray once the recipient clicks the document link in the email. PDF files are automatically displayed in the Conga PDF Viewer.
Composer Link Service supports sending PDF, Word, Excel, and PowerPoint files. The Conga PDF Viewer only supports PDF files.
