Confluence : Moving an attachment using Cloud REST API

[Supreetha Upadhya]

I'd like to move an attachment to a different space (i.e, update the parent container of an attachment in a Confluence page) using Cloud REST API and "curl" command. I looked up REST API endpoint URL and found this: 

PUT /rest/api/content/{id}/child/attachment/{attachmentId}

Could somebody provide an example for a correctly constructed JSON input to achieve this? I tried the one below to move an attachment called "test.jpeg" with ID "att000" and current version 5 to parent with ID 1234, but it fails:

curl -v -u 'admin:password' -X PUT -H 'Content-Type:application/json' -d '{"id":"att000","type":"attachment","title":"test.jpeg","version":{"number":5,"minorEdit":false},"ancestors":[{"id":1234}]' -H ‘X-Atlassian-Token:access-token' https://test.atlassian.net/wiki/rest/api/content/170234/child/attachment | python -m json.tool

Given below is the error message

< HTTP/1.1 415 Unsupported Media Type
.
.
.
No JSON object could be decoded

Thank you for your time!

Hello Supreetha!

Have a look at this documentation: https://docs.atlassian.com/confluence/REST/latest/#content/{id}/child/attachment-createAttachments

Your media-type is wrong - you shouldn't be seding JSON around for an attachment. Example curl requests and explanation are in the documentation link.

Cheers!
