Just a heads up: On March 24, 2025, starting at 4:30pm CDT / 19:30 UTC, the site will be undergoing scheduled maintenance for a few hours. During this time, the site might be unavailable for a short while. Thanks for your patience.
×Hi there, I have searched but with no luck so far? Is it possible to post .png images to a confluence page using either Rest API or Java API?The .png images are sourced from a 3rd party tool and the idea is to build a plugin that will export and import (post) the .png images to Confluence pages?
Any help will will be most welcome?
Hello Etienne,
Thank you for your inquire.
You could be running the following in Python, for instance:
# =============== # upload attachment # =============== import requests import json # [CONFLUENCE-BASE-URL], i.e.: http://localhost:8090 # [CONTENT-ID], get content ID by running '[CONFLUENCE-BASE-URL]/rest/api/content' url = '[CONFLUENCE-BASE-URL]/rest/api/content/[CONTENT-ID]/child/attachment' headers = {"X-Atlassian-Token": "nocheck"} data = {"comment":"this is my file"} # please, uncomment to attach inline content #files = {'file': ('report.xml', '<?xml version="1.0" encoding="UTF-8"?><note><to>RECIPIENT</to><from>SENDER</from><heading>ATTACHMENT</heading><body>CONTENT</body></note>')} # please uncomment to attach external file #files = {'file': open('text.txt', 'rb')} #files = {'file': open('image.png', 'rb')} # upload file to page # [USERNAME], i.e.: admin # [PASSWORD], i.e.: admin r = requests.post(url, data=data, auth=('[USERNAME]', '[PASSWORD]'), files=files, headers=headers) print(r.status_code) print(r.text)
Alternatively, you could be running the following cURL command:
# [USERNAME], i.e.: admininstrator # [DOMAIN], i.e.: mycompany # [CONTENT-ID], i.e.: 9666562 curl -D- -u [USERNAME] -p -H "X-Atlassian-Token: nocheck" -X POST -F file=@/full/path/to/image.png https://[DOMAIN].atlassian.net/wiki/rest/api/content/[CONTENT-ID]/child/attachment
If you find this answer useful, I would kindly ask you to accept it so the same will be visible to others who might be facing the same issue you have inquired.
Thank you for your understanding.

Thanks for the very useful python example. I'm curious though, it seems to work for me when I first upload but if my change the file I want to attach and then run the python program again, I get a 400 Bad Request.
Is there some magic needed to allow updating an attachment?

I am using same CURL command to upload multiple html files but its not allowing me to do so. Could you please suggest. I am using Confluence cloud.
curl -D- -u $USERNAME:$PASSWORD -X PUT -H "X-Atlassian-Token: nocheck" -F "file=@code/pydoc/*.html" -F "minorEdit=false" 'https://alm-tuigroup.atlassian.net/wiki/rest/api/content/504955238/child/attachment'

I think the answer to Dan McMahill's question above is that once an attachment is attached, if you want to update that attachment, then you have to post to a different URL: you need to post to the attachment's data resource. In my case the resource for the attachment update was:
.../rest/api/content/253493424/child/attachment/281051237/data
I was able to find the resource for the attachment via:
curl -k https://.../rest/api/content/253493424/child/attachment | python -mjson.tool

Using the Confluence Command Line Interface (CLI) might make it easier - use the addAttachment action.

You can do a multipart POST call to upload multiple attachments at once. I wrote something like the following with apache http client mime library.
public int uploadAttachments(String path, List<String> attachmentNames) throws Exception {
CloseableHttpClient client = getClosableHttpClient();
HttpPost request = new HttpPost(buildURI(path));
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
for (String s : attachmentNames) {
if ("binary".equals(Utils.getFileType(s))) {
// System.out.println(s);
// builder.addBinaryBody("file", null)
builder.addBinaryBody("file", new File(s), ContentType.DEFAULT_BINARY, new File(s).getName());
} else if ("text".equals(Utils.getFileType(s))) {
builder.addBinaryBody("file", new File(s), ContentType.TEXT_PLAIN, new File(s).getName());
} else {
}
}
HttpEntity entity = builder.build();
request.setHeader(HttpHeaders.AUTHORIZATION, "Basic " + this.creds);
request.setHeader("X-Atlassian-Token", "no-check");
request.setEntity(entity);
// System.out.println(EntityUtils.toString(request.getEntity()));
CloseableHttpResponse response = client.execute(request);
// System.out.println(EntityUtils.toString(response.getEntity()));
return response.getStatusLine().getStatusCode();
}

The python code will move the file in the attachment section. How can we show it in the page content. Any help?

Moving attachments from its current space to a different space:
Using curl, the following can be used to attach the file to a page in a different space:
curl -v -u 'admin:XXX’ -X PUT -d '{"id":"attXXX”,”type":"attachment","title”:”xxx.jpeg","status":"current","ancestors":[],"version": {"number":"2"},"container": {"id": "34514","type": "page","status": "current","title": "Andro Homepage!","space": {"id": 34513,"key": “AR”,”name": "Andro"}}}' -H 'X-Atlassian-Token:<access-token>' -H 'Content-Type:application/json' https://XXX.atlassian.net/wiki/rest/api/content/<parent page id>/child/attachment/attXXX | python -m json.tool
