Sharepoint online: Programmatically post to news feed - sharepoint

Question

I want to create a webpart which can post data to a specific Sharepoint's news feed, but have been unable to locate any good documentation. The only link I found was:
https://msdn.microsoft.com/library/e9ad06a1-831d-8ed0-c76e-8b049f14216f%28Office.15%29.aspx
My question is: what method can I use to post data to a Sharepoint-site's news feed?
In the link they mention that you can post to "the URL of a site feed". Is that the same as a news feed? Anyone who has done something similar?

We can use JSOM or REST API to achieve it.
REST API:
<script type="text/javascript" src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<script type="text/javascript">
$(function(){
$.ajax( {
url: weburl + "/_api/social.feed/my/Feed/Post",
type: "POST",
data: JSON.stringify({
'restCreationData':{
'__metadata':{
'type':'SP.Social.SocialRestPostCreationData'
},
'ID': null,
'creationData':{
'__metadata':{
'type':'SP.Social.SocialPostCreationData'
},
'ContentText': "the post content text",
'UpdateStatusText':false
}
}
}),
headers: {
"accept": "application/json;odata=verbose",
"content-type":"application/json;odata=verbose",
"X-RequestDigest": $("#__REQUESTDIGEST").val()
},
success: function(){
console.log("success to post ");
},
error: function (xhr, ajaxOptions, thrownError) {
alert("POST error:\n" + xhr.status + "\n" + thrownError);
}
});
});
</script>
JSOM:
<script type="text/javascript" src="/_layouts/15/sp.userprofiles.js"></script>
<script type="text/javascript">
SP.SOD.executeOrDelayUntilScriptLoaded(WritePost, 'SP.UserProfiles.js');
function WritePost() {
var oclientContext;
var ofeedManager;
var oresultThread;
// Initialize the current client context and the SocialFeedManager instance.
oclientContext = SP.ClientContext.get_current();
ofeedManager = new SP.Social.SocialFeedManager(oclientContext);
// Add a link to be included in the post.
var olinkDataItem = new SP.Social.SocialDataItem();
olinkDataItem.set_itemType(SP.Social.SocialDataItemType.link);
olinkDataItem.set_text('My blog url');
olinkDataItem.set_uri('http://sundarnarasiman.net');
var osocialDataItems = [ olinkDataItem ];
// Set up the post content
var opostCreationData = new SP.Social.SocialPostCreationData();
opostCreationData.set_contentText('The text for the post, which contains a {0}.');
opostCreationData.set_contentItems(osocialDataItems);
// Write the post
oresultThread = ofeedManager.createPost(null, opostCreationData);
oclientContext.executeQueryAsync(WriteSucceeded, WriteFailed);
}
function WriteSucceeded(sender, args) {
//$get("ResultMessage").innerText = 'Successfully posted the message to Posts';
}
function WriteFailed(sender, args) {
//$get("ResultMessage").innerText = 'Failure in writing message' + args.get_message();
}
</script>
