Display link attachments in comments

We have implemented the following API .
https://docs.atlassian.com/jira-servicedesk/REST/4.8.1/

By API
POST / rest / servicedeskapi / request / {issueIdOrKey} / attachment
Attach the file.

But we can’t see it in the comments.

We still can’t use the following version.

https://developer.atlassian.com/cloud/jira/service-desk/rest/#api-rest-servicedeskapi-request-issueIdOrKey-attachment-get

Is there a solution?

@MasoudSharifi - not that this is your problem; however, just wanted to note that you’re referencing the JSD server (on-prem) REST API docs on your first link, and then the cloud docs on the second. Are you working on a server or cloud instance?

When you post an attachment, I assume you’re getting a 201 response on your API call. What is your entire POST body request look like? Please include the entire request body, including fields like properties.additionalComment and properties.public.
