API Upload File

Hello all,
I've been trying to attach a file to a ticket via uploads API and the problem that I am encountering is that the file successfully attaches but then when I try to open the file it download to my PC but when I try to open it says file type not supported.

• I am making the request from ServiceNow through post request to https://example.zendesk.com/api/v2/uploads.json
• response status code 201
• Then I take the token in the response to create a new ticket in ZD.
• response status code 201
• file type is JPG
• file size is 1.9 MB
