Problem statement: I have a requirement wherein we receive file in Appian from a third party system. For security reasons we want to restrict only few file extension.
I have created a WEB API using a ' Document Upload' Template , so that external systems can push documents to Appian.
I want to return error code in response when some hits this WEB API and upload files with extension other than .xlsx.
I have used document(http!request.body, "extension"), however this does not restrict document to be added to target folder.
Is it possible that , WEB API returning error code and not even allowing files with specific extension to be added to target folder.

There is no way to restrict it as of now (still we can show validation error as a response) . Appian converts binary file request to appian document immediately when the external system hits Api . One solution for this is you can create a scheduler to delete unnesasary documents which will run daily or weekly
