How to get filename from media node id

[Miloš Zeman]

Hi, 

I would like to ask you, how can I get filename or attachement id linked on document node media https://developer.atlassian.com/cloud/jira/platform/apis/document/nodes/media/

Documentation says, that from attrs.id I can get eg. filename, but its not written how, on which endpoint or whatever...

I spend almost an hour to find how to get this, but I found nothing.

Thanks anyone who will give me the answer.

Hi Rostislav,

All attachments in Jira are always bound to a specific issue in Jira.  As such, we can find both the id and the filename of the attachments by doing a GET to the /rest/api/3/issue/{issueIdOrKey} endpoint and passing it the issuekey or the issue id number where that attachment is bound to.   So for example, if my issuekey is SCRUM-123, and I know it has an image attached to that issue, I can do a REST call of

GET /rest/api/3/issue/SCRUM-123

and I'll get back something like this:

    "attachment": [
      {
        "id": 10000,
        "self": "https://your-domain.atlassian.net/rest/api/3/attachments/10000",
        "filename": "picture.jpg",
        "author": {
          "self": "http://your-domain.atlassian.net/rest/api/3/user?accountId=99:27935d01-92a7-4687-8272-a9b8d3b2ae2e",
          "key": "mia",
          "accountId": "99:27935d01-92a7-4687-8272-a9b8d3b2ae2e",
          "name": "mia",
          "avatarUrls": {
            "48x48": "http://your-domain.atlassian.net/secure/useravatar?size=large&ownerId=mia",
            "24x24": "http://your-domain.atlassian.net/secure/useravatar?size=small&ownerId=mia",
            "16x16": "http://your-domain.atlassian.net/secure/useravatar?size=xsmall&ownerId=mia",
            "32x32": "http://your-domain.atlassian.net/secure/useravatar?size=medium&ownerId=mia"
          },
          "displayName": "Mia Krystof",
          "active": false
        },
        "created": "2019-04-01T14:51:03.159+0000",
        "size": 23123,
        "mimeType": "image/jpeg",
        "content": "https://your-domain.atlassian.net/jira/attachments/10000",
        "thumbnail": "https://your-domain.atlassian.net/jira/secure/thumbnail/10000"
      }
    ],

Along with a lot more json data.  But this section will tell us what attachments a Jira issue has, the attachment ids, and the attachment filenames.

I hope this helps.
