ServiceDesk Plus On Demand API V3 - Error with adding attachment to Request

Hi,

I have a problem with adding attachments to requests using the API V3. The attachment seems to be uploaded (status code 200), but it does not appear on the Request screen.

It is important that:

This is with ME SDP On Demand.
When ME SDP On Demand used the earlier API, I could successfully attach files to a Request.
Authentication is fine, I can create a request using the API.

I suspect that the problem is that (according to the documentation https://www.manageengine.com/products/service-desk/sdpod-v3-api/SDPOD-V3-API.html#add-attachment-to-a-request), "addtoattachment" should be set to "true", but I don't know how to set it in the HTTP request.

Details:

I make the HTTP Post to this URL:

https://sdpondemand.manageengine.com/api/v3/requests/19659000000819049/uploads?scope=sdpodapi&OPERATION_NAME=ADD_ATTACHMENT

HTTP headers:

This is the response I get:

{"response_status":[{"status_code":2000,"status":"success"}],"files":[{"content_type":"text/html","size":"8925","file_id":"77006","name":"SU53_output_passed_157_S72_20180816.html","content_url":"/requests/uploads/77006"}]}

Notice that the content_url is different from the one in the documentation:

$ curl api/v3/requests/{request_id}/uploads \

-H "Accept: application/vnd.manageengine.sdp.v3+json" \

-H "Authorization: ad88xyszde6c84565aae47dweraf8cc05b" \

-F "filename=@local_file_path" -F "addtoattachment=true"

"status": "success"
