How to convert Base64-encoded documents as URL ?
Currently working on a requirement in PEGA where we receive Base64-encoded content from a client-side API. The content could be a PDF, image, DOC, or any other type of document. Our goal is to convert this document as URL so we can map it to the constellation UI using URL property so when the user click on that the user could be able to see the document on new tab.
Is there any approach to convert the Base64 content into a URL. ( i have try to convert the content in to data URL but using data URLs is not feasible because the document size can vary and might be large and the browser did not support large content.)
Is there a recommended way to achieve this

@AshinaShanuka The practical way is to not turn Base64 into a browser URL directly, but to store the decoded bytes somewhere and then expose a normal HTTPS link. In Pega, decode the Base64 to a binary stream, create an Attachment (or save it to your attachment repository), and persist it against the case or a document record. If your attachment store is S3/Azure/Blob (or any external doc store), call a service to upload the file and get back a pre-signed URL (time-limited, secure). Make sure you set the right Content-Type (pdf, png, docx) and file name so the browser opens it correctly. Save that returned URL in a property (like .DocumentURL). In Constellation, map the URL property to a link so the user click opens a new tab. This avoids Data URL size limits and works for large documents. Add access control (token/TTL) so only authorized users can open the link.
