Attachment issue with ServiceDesk Plus (ManageEngine)

[SD_Akshay]

We are integrating ServiceNow with ICC ManageEngine 

In it we are attaching attachment to their Request (From our Incident), but they have provided the payload template in python script 

aturl = f"https://abc.com/''
fileName = "test.txt" #data.csv
filePath = "E:\\test.txt"
fileType = mimetypes.guess_type(filePath)

files = []
fileObj = ('file0', (fileName,open(filePath,'rb'), fileType))
files.append(fileObj)
data = files
response = requests.put(aturl,headers=headers,files=data,verify=False)
print(response.text)

Like this we don't know 

fileObj = ('file0', (fileName,open(filePath,'rb'), fileType))

How to pour the data in above path. In it file0 is static value and rb as well static value 

If anyone have done this previously or have dealt with the same thing please suggest what to do.

We have tried sending file Via Postman in their EndPoint and it is going but we can't through REST API.

We finally were able to solve this issue. We created the below Business Rule on Incident table 

Table :- Incident

When : After Update

(function executeRule(current, previous /*null when async*/ ) {

    var grGetAttach = new GlideRecord("sys_attachment");
    grGetAttach.addQuery('table_sys_id', current.sys_id);
    grGetAttach.query();

    while (grGetAttach.next()) {
        try {

            var json = new JSON();
            var obj = {},
                data;

            obj.note = {};
            obj.note.description = 'Attchment Created';
            obj.note.show_to_requester = true;
            obj.note.mark_first_response = false;
            obj.note.add_to_linked_requests = true;

            data = json.encode(obj);

            var r = new sn_ws.RESTMessageV2('ME Integration', 'Create_Notes');
            r.setRequestHeader("TECHNICIAN_KEY", "0CE7xxxxxxxxxxxxxxxxxxxxxxDCF");
            r.setStringParameterNoEscape('request_id', current.correlation_id.toString());
            r.setQueryParameter("input_data", data);
            r.setStringParameterNoEscape('request_id', current.correlation_id.toString());

            var response = r.execute();
            var responseBody = response.getBody();
            var httpStatus = response.getStatusCode();
            var result;

            try {
				result=JSON.parse(responseBody);

                gs.log("Error: parsing Create notes resonse: " + parseError.message, " ME Integration");
                continue;
            }
