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.

we also met the issue, after we migrated projects from server instance to cloud instance, we sync the attachments to cloud project,  the attachment displayed in description and comments are failed, after checking with api, we found the good attachments in comment have a  "occurrenceKey" key , but how to find the right occurrenceKey key for the attachment? we don't know that.
