Confluence file attachment issue using the REST API

This is the error response i get..

"{ statusCode: 400 message: "At least one attachment file must be included." }".

I know the HTTP POST message is well formatted as a multipart/form-data, any suggestions what might be missing

I have the same issue, did you solve it?

My request is looking like this (with the actual values in the <tokens>

POST https://&lt;mywiki&gt;.atlassian.net/wiki/rest/api/content/&lt;pageid&gt;/child/attachment HTTP/1.1
X-Atlassian-Token: nocheck
Accept: application/json, application/xml, text/json, text/x-json, text/javascript, text/xml
User-Agent: RestSharp/105.2.3.0
Content-Type: multipart/form-data; boundary=-----------------------------28947758029299

Thank you

 

I got this error, too when used Application Link on JIRA 7, did you resolve it?

Well yes, I dowloaded curl, tried the examples from the documentation and compared the requests in Fiddler. The main difference was actually that  the Content-Disposition name in the multipart must be "File". Apart from that I actually ended up building the multi part my self

So the request that worked for me became:

POST https://&lt;mywiki&gt;.atlassian.net/wiki/rest/api/content/&lt;pageid&gt;/child/attachment HTTP/1.1
X-Atlassian-Token: nocheck
Accept: application/json, application/xml, text/json, text/x-json, text/javascript, text/xml
Content-Type: multipart/form-data; boundary=-----------------------------28947758029299
Host: &lt;mywiki&gt;.atlassian.net
Cookie: studio.crowd.tokenkey=&lt;myvalue&gt;
Content-Length: 40797
Accept-Encoding: gzip, deflate

-------------------------------28947758029299
Content-Disposition: form-data; name="File"; filename="&lt;filename&gt;.png"
Content-Type: application/octet-stream
