My requirement is described below.

  1. User uploads the document through web-app and document saves in to shared location.
  2. Application service (cron job or server code) , selects the documents and extracts the details.
  3. Cron job send the details to SharePoint rest api which is protected by azure AD. (Oauth protocol)

I have a valid AZURE client ID and Secret ID which has application level access permission. I got access token by using AZURE client ID and Secret ID from AZURE AD with help of simple JAVA code but am getting following error when i call sharepoint online REST service using Oauth access token.

Error : {"error_description":"Exception of type 'Microsoft.IdentityModel.Tokens.AudienceUriValidationFailedException' was thrown."}

What does it mean? Can anyone help me resolve the issue ?

As SharePoint Online has strict safety standards, authentication for working with REST API consists of three steps:

1.Get the security token from Microsoft authentication portal.

2.Get the cookies from the SharePoint Online server.

3.Get the signature for requests to the SharePoint Online server.
