We got a requirement to use SandBlast Threat Extraction  process, for cleansing the files.

SandBlast Threat Extraction, is a solution by ‘Check Point’ company,  which removes exploitable content, including active content and embedded objects, reconstructs files to eliminate potential threats.

‘Threat Extraction’ Upload API, requires following parameters

• Header
  • Authorization
  • Content-Type
• Body
  • File Content
  • request (This is string)

If you notice, we need to pass ‘File’ as well as ‘Data’ to the API.

As of now, Sandblast doesn’t have a native .Net library to make API calls. So I’ve used Postman tool as a starting point for my development.

Below is the step-by-step, to pass ‘File’ and ‘Data’ in request ‘Body’, using Postman

• Open Postman tool
• Create a new ‘Request’

• Set the method as ‘Post’ and URL.
• From the ‘Body’ tab, select ‘form-data’ option
• To pass the ‘File’,  add a new ‘KEY’ of type ‘File’ and browse the file in ‘VALUE’ parameter.
• To pass the ‘Data’, add a new ‘KEY’ of type ‘Text’ and set the ‘VALUE’

Generate C# code from the Request:

• Postman has an amazing feature to generate the code in your required language.
• Click on ‘Code’ link and for C#, choose ‘C# (RestSharp)’ option.

• In your C# project, add RestSharp NuGet package.
• Paste the code in your class file and you are good to go now.

If anyone having struggling to use Sandblast API’s, post in comments section and I will address.
