SharePoint 2013 REST API - Post SocialRestPostCreationData

Question

I’m currently working on a small application to push Post to a SharePoint 2013 SiteFeed using the Social.Feed API.

Basic Posts using the following JSON Object structure are working fine but I’m struggling using a Social-Attachment.

As long I’m referencing to the files located somewhere in the internet everything works. Posts will create listitems in micro-feed list with HTTP-Reference to the Files. The Object I'm using is set up like this

    var creationInfo = new
    {
        restCreationData = new
        {
            __metadata = new { type = "SP.Social.SocialRestPostCreationData" },
            ID = array,
            creationData = new
            {
                __metadata = new { type = "SP.Social.SocialPostCreationData" },

                Attachment = new
                {
                    __metadata = new { type = "SP.Social.SocialAttachment" },
                    AttachmentKind = 0,
                    ContentUri = "https://www.google.com/images/icons/hpcg/ribbon-black_68.png",
                    Description = "Look at this",
                    Name = "Test",
                    Uri = "https://www.google.com/images/icons/hpcg/ribbon-black_68.png"
                },
                ContentText = text,
                UpdateStatusText = false,
            }
        }
    };

Is there a possibility to use a local file instead? - Removing the google paths and using a local path in ContentUri will end up in a BAD-Request error.

I guess that the files has to be uploaded somehow before.

Thanks for you help.

After some trying we now ended up with the following solution.

Before we create the SocialPost, we upload the picture into an image gallery where all Feed users have access to.
Then we create the post containing a link to the image

-> This will do the trick.
