Integration with another Document System

Question

Hello, 
 
 we need to integrate Appian with another Document Managemnet System. 
 
 This document System doesen't support CMIS and they can only create a web service that return a base64 string, we need to get this string, convert it directly in an interface without starting any process so that users can download it. Any Suggestions? 
 
 We have just upgraded our on-premise Appian to 18.2, so it is not possible to imagine that we will do another upgrade before one year.

Hi marcoc918 - 
 You will need to consider adjusting the specifications of your overall requirement, in some aspect, to reach your end goal. 
 In order to present an end user with an Appian document download link, the document must exist as a document in Appian. 
 A base 64 string can be converted into a document, but it doesn't represent a document until after it's been converted. 
 The conversion typically involves a process. 
 If your document management system supports parameterized document download (or view) links, (some systems, such as onBase, do), you could put an expressionable safe link on a SAIL interface that enables the user to retrieve the document directly from the document management system. 
 Take a look at the shared components in the AppMarket that are commonly used to address these sorts of use cases.
