aws = new awscfml.aws(argumentCollection=initConfig);

// identify & read local file
filePath = "d:\files\temporaryFile.zip";
zipFileData = fileReadBinary(filePath);
remoteObjectKey = "temp/MyZipFile.zip";

// configure file data for upload
uploadArgs = [
	"bucket": #bucketName#

// perform upload
apiResponse = aws.s3.putObject(argumentcollection=args);

// dump API response
writedump(var=apiResponse, label="S3 putObject apiResponse");
