Download attachment from Confluence with OAuth 2.0

[Karol Leszczyński]

Hi,

I'm using OAuth 2.0 to login users to Confluence. I want to get content of pages with attachments.

To get attachments info i use this method:
https://api.atlassian.com/ex/confluence/{cloud_id}/wiki/rest/api/content/{content_id}/child/attachment

response is like this:

"_links": {
"webui": "/pages/viewpageattachments.action?pageId=xxx&preview=zzz",
"self": "https://aaa.atlassian.net/wiki/rest/api/content/ccc",
"download": "/download/attachments/{attachments_id}/{file_name}?version=1&modificat

ionDate=1744797121672&cacheVersion=1&api=v2"
}

I trying to use this download url and construct API call but nothing is working. I tried multiple prefixes like https://api.atlassian.com or myconflience.atlassian.com and non of them are working. I'm can find multiple post from 2021 from people claiming they also have problems with it but i'm not sure it was fixed.

regards

Hey Karol,

you can check with url like this one: https://yourdomain.atlassian.net/wiki/rest/api/content/{id}/child/attachment. However, based on Clonfluence API doc this method is going to be deprecated and replaced by new one in api v2.

Potentialy v2 alternative: https://yourdomain.atlassian.net/wiki/api/v2/pages/{id}/attachments

https://developer.atlassian.com/cloud/confluence/rest/v1/api-group-content---attachments/#api-wiki-rest-api-content-id-child-attachment-get

https://developer.atlassian.com/cloud/confluence/rest/v2/api-group-attachment/#api-pages-id-attachments-get

Method you provided do not allow to download attachment, it only returns metadata.

You are right. I thought it was the method you were using to get the attachments. Not sure if that will help you, but I've seen that using "https://yourdomain.atlassian.net/wiki" before download link, starts downloading in browser straight away. Not sure how it's going to behave while running from script.

https://yourdomain.atlassian.net/wiki/download/attachments/{attachments_id}/{file_name}?version=1&modificationDate=1744797121672&cacheVersion=1&api=v2"

In Postman call this return me login page in html even if i attached Access token. 

When i tried this link in browser it went in to some infinite look of redirects.
