How to convert Base 64 format to document?

Question

I am looking for a way to convert Base 64 format string to document in Appian. 
Note: The base 64 format string is coming as a JSON input request string when external system hits Appian web API. So, I don't have any integration object here to auto-convert the same to document using default Appian functionality in integration object. I need to receive this format, convert into document, store in Appian document folder and show the same in UI (without using integration).

We also have the same scenario like we get the document as base64 string when dot net system hits our API, we saved the string in Database table and then we used the below plugin to convert the string to document and store it in Appian folder.
