            let url = BASE_URL + '/integration/v1/generatePreSign/' + templateType + '?fileName=' + fileName;
//templateType will be 'sales' or 'purchases'
            let response = https.get({

                headers: headerObj
            });
            return response;

function uploadFiletoStorage(preSignedURL, csvData) {
            let sendFileHeader = {
                "Content-Type": "application/vnd.ms-excel"
            }
            let rqBody = csvData;

            let sendFileResponse = https.put({
                url: preSignedURL,
                headers: sendFileHeader,
                body: rqBody
            });
            return sendFileResponse;
        }

function triggerFileIngestion(BASE_URL, AUTH_TOKEN, preSignedURL, templateType, fileName) {
            let triggerFileHeader = {
                'x-cleartax-auth-token': AUTH_TOKEN,

            let triggerUrl = BASE_URL + '/integration/v1/ingest/file/' + templateType
            let triggerFileResponse = https.post({
