Moving a file using Azure File Storage / Azure Blob Storage

Does anyone have any experience in using the Azure File Service / Azure Blob Service ?
We are currently creating a file within Appian and move it to an on premise server using SFTP. At some point in the future, the on premise server will be replaced and we have the need to move the file to an Azure Server. We've been advised to make use of the above service but are struggling to get this to work.

Either the requests we are building are incorrectly formatted or it's not recognizing the document object at all.

It would be great to know if anyone else has a solution, the examples i've found, are not Appian specific and so far haven't helped ...
