baseUrl= [baseUrl stringByAppendingString:spreadsheetId];
baseUrl = [baseUrl stringByAppendingString:@"/values:batchUpdate/"];



NSMutableDictionary * params=[[NSMutableDictionary alloc]initWithObjectsAndKeys:@"USER_ENTERED",@"valueInputOption", nil];

NSURL *postURL=[GTLUtilities URLWithString:baseUrl queryParameters:params];

NSLog(@"base url is %@", postURL);

GTLObject * body=[[GTLObject alloc]init];



NSMutableArray * titleArray=[[NSMutableArray alloc]initWithObjects:@"Customer ID",@"Customer Name",@"Latitude",@"Longitude" ,@"Last_Updated_At",nil];
NSMutableArray * wheelArray2=[[NSMutableArray alloc]initWithObjects:@"rt",@"SHJ",@"150.00",@"100.00",@"2:00:00", nil];

//[contentArray addObject:titleArray];



NSMutableDictionary * batchParams=[[NSMutableDictionary alloc]initWithObjectsAndKeys:@"USER_ENTERED",@"valueInputOption", nil];


NSMutableArray * batchParametersContentArray=[[NSMutableArray alloc]init];

[batchParametersContentArray addObject:batchParametersTitlesDict];

[batchParametersContentArray addObject:batchParametersContentDict];

[batchParams setObject:batchParametersContentArray forKey:@"data"];


NSLog(@"batch params are %@",batchParams);


body.JSON=batchParams;
