Hi @Aditya Kristuaji 

You need to create Backend .NET logic using Integration Studio to achieve this. Follow the below steps to create the backend logic.

1: Create Extension

• Open Integration Studio
• Create new extension (e.g., ZipPasswordExtension)

2: Add .NET Library

• Add reference to Ionic.Zip.dll (DotNetZip)

3: Create Structure Create a structure FileItem:

• FileName (Text)
• FileContent (Binary Data)

4. Create Server Action CreatePasswordZip Inputs:

• Files (List of FileItem)
• Password (Text)

Output:

• ZipBinary (Binary Data)

5. Implement C# Code

6. Publish Extension

7. Use in OutSystems

• Call CreatePasswordZip
• Pass file list + password
• Return Binary Data

8. Download File

• Content-Type: application/zip
• FileName: SecureFiles.zip

I have checked other solution like adding CDN from ZIP.JS but it did not work. So, use the above .NET backend approach to add password.

Thanks,

Sudip
