Can I edit a Yammer message via the REST API?

Contributor

I have code that can post and delete messages via the rest API.  Now that Yammer allows editing of posts, I would like to update posts via the REST API as well.  Is this possible?

 

I haven't seen any documentation and I can't get it to work yet. I have seen via Fiddler that the UI does a REST call such as:

 

 

PATCH https://www.yammer.com/api/v2/messages/<messageid>
Authorization: Bearer <token>
Accept: applicationhttps://techcommunity.microsoft.com/json, text/javascript, */*; q=0.01
(other headers)

{"body":"<simple body text>","recipients":[],"references":{"ogos":[]}}

If I try this manually via Postman I get a 404.  Is this because it isn't supported via the REST API or do I just need to work more on getting the headers/body correct?  I realize that the UI is providing several headers values in addition to Authorization that may "authorize" the request like cookies, browser-token, oauth_token, and _session, but I know that my simple POST/DELETE calls can get by with just the Authorization header.

Well, I posted too soon.  I figured it out.  I somehow had a typo in the URL and was posting to v1/messages instead of v2/messages.

Documented in a dev blog post [1], there isn't a supported endpoint for editing posts. The endpoint you found is undocumented, and therefore might change at any point without notice.

The edit REST API call through PATCH works even now?, I tried PATCH for edit post, i am getting 404.

PATCH https://api.yammer.com/api/v1/messages/939539391 404 (Not Found)

Hi, 

By any chance, is there any information about REST api for edit comments functionality ?.

 

Thanks,

Hi,

I am evaluating Yammer for my company need, any chance to share the code you've developed to post and delete via API ?

 

thanks

I would also really like to know how you implemented your edit solution.

 function editComment(id) {
yam.platform.request({
url: "https://api.yammer.com/api/v2/messages/"+id,
method: "PATCH",
data: {
"body" : "Edited comment"
},
success: function (res) { //print message response information to the console
alert("The request was successful.");
console.dir(res);
},
error: function (res) {
alert("There was an error with the request.");
console.log(res)
}
})
}

 

When using "https://api.yammer.com/api/v2/messages/", I get 2 errors. First, 503 (Service Unavailable) and a "Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource." error.

 

But when I use "https://www.yammer.com/api/v2/messages/", I don't get the 503 error, only the cross domain one.

 

This is strange, because I can get messages from Open Graph Objects (OGO), post comments and replies and create OGO at the same time. I don't know why I get this cross domain error only with this endpoint.

Am I doing it all wrong? Because it works for everything else. 

I also know that officially, there is no endpoint

Do you succeed in posting and deleting messages via API ? If yes would it be possible to share the code ?
thanks

Solution

There you go

 

To add a comment :

function addComment() {
yam.platform.request({
url: "https://api.yammer.com/api/v1/messages.json",
method: "POST",
data: {
"body" : "Commment Content",
"group_id": "GroupID",
"replied_to_id": "commentID",
"og_url": "URL of current page",
"og_title": "Title of the Open-Graph Object",
"og_description": "OGO description",
"og_private": "true"
},
success: function (res) { //print message response information to the console
alert("The request was successful.");
console.dir(res);
},
error: function (res) {
alert("There was an error with the request.");
console.log(res)
}
})
}

All the parameters starting with"og_" are to create an open graph object which links the comment with a page. If you don't want one, just don't use any of the "og_" fields. Also, you can post directly to a group by using "group_id". If the group is set to private and you want the OGO to also be private, set true to "og_private".

And if your comment is a reply to an other comment, get that first comment id, then use "replied_to_id".

 

 

To delete comments :

function deleteComment(id){
yam.platform.request({
url: "https://api.yammer.com/api/v1/messages/"+id,
method: "DELETE",
success: function (res) { //print message response information to the console
alert("The request was successful.");
console.dir(res);
},
error: function (res) {
alert("There was an error with the request.");
console.log(res)
}
})
}

It is very straightforward. Pass the id of the comment you want to delete and there you go! In case of success, the "console.dir(res);" command should return nothing, because the object would be deleted. But you can do w/e you want in the success and error sections.

Thank you very much for the code !!! How do you manage the login ?

Same issue here, about almost an year, and the same error persists, did you figured out any solution to editing a message via API?

 

Analising the Yammer with the fiddler i saw that yammer uses an version 2 of the api

 

PUT https://www.yammer.com/api/v2/messages/ HTTP/1.1

 

and send the data in JSON format as follows:

 

{"content_state":{"blocks":[{"key":"0","text":"reply reply","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}}],"entityMap":{}},"recipients":[],"references":{"ogos":[]}}

But i cannot replicate this behavior on my WebPart (yes, I using SPFx framework to implement a webpart that perform some integration with Yammer)

 

Best Regards

Sergio.

@Charles Pauze-Robert  I tried your code using "PATCH" but its not working for me and giving the same error which you were facing . Do you succeed in editing messages via API ? If yes would it be possible to share the code or some more hints ?
thanks

Is there a way to edit the post using API? I do not see in official document that Yammer expose any API for editing a post.
