Document sharing with external system based on Document ID

Hello,

We have a requirement to share the document stored in the Knowledge center with the ASP.net application.

Please see the use case below:

When we create a document in the Knowledge Center, we store the Appian document ID in our database.

We are wondering how we can successfully display these documents on the external site built on the ASP.net framework.

Please let us know the step-by-step process and whether any authentication is needed to access these documents based on the document ID in the Appian environment."
