We have a requirement to integrate an antivirus solution with the Sharepoint server programmatically.
When a user adds/updates a document perform a scan using SDK of the antivirus and based on the result allow/block the document. So we are expecting to receive a callback when a user uploads/downloads any documents. This does not apply to the Sharepoint online. We have to achieve this programmatically(C# is the preferred language).
We are struggling to find enough documentation regarding the same.
The documentation we can find so far is mentioned below but it doesn't seem to have enough information to get started and also we are not sure if it is still relevant,
We would like to know possible approaches/documentation related to this.
