Uploading attchment using /wiki/rest/api/content/{pageid}/child/attachment results in status 415

[Leon André Bergman]

Hi.

I am trying to set up a call to upload files to pages, but I keep hitting a snag where it tells me 415 Unsupported Media Type.

I'm trying to go by what this documentation says:
https://developer.atlassian.com/cloud/confluence/rest/v1/api-group-content---attachments/#api-wiki-rest-api-content-id-child-attachment-put

In Postman I've set up other calls, that work fine. including a GET on /wiki/rest/api/content/{pageid}/child/attachment

For the POST I have set up the header 
X-Atlassian-Token with value nocheck

The body is:

{

    file: "{full file path}"

    minorEdit: true

    type: image

}

I have also tested:

{

    file=@"{full file path}"

    minorEdit="true"

    type=image

}

and

{

    file=@"{full file path}"

    minorEdit="true"

    type="image"

}

Does anyone know what the correct working call would be in postman?

Hi @Leon André Bergman

According to the documentation you linked you are missing the Content-Type header in your request, the Content-Type should be set to multipart/form-data for file uploads.

Try adding the following header to your request:

Content-Type: multipart/form-data

Also, make sure that the file path you are using in your request body is correct and that the file exists.

This was part of the issue.
But I only got it to work after I switched from using Raw , to form-data in the body in Postman.

Added a line with they key st to file.
Under value I browsed for the file I wanted to upload.
I had to show the Content type field under form-data, and set it to multipart/form-data for that file.

Seems this call can send multiple files, and you have to specify content type pr file. Which makes sense once you know its a multi file call, not single file.
