Getting Error 400 when calling Instagram API in Objective-C

I am writing an app in iOS that integrates to Instagram. I am getting an Http Error 400 from Instagram when using the Like API call. The other API calls are working fine however. Here is part of my code where I post the request

{
    NSDictionary* params = [NSDictionary dictionaryWithObject:_accessToken forKey:@"access_token"];
    NSString* path = [NSString stringWithFormat:kUserLikeEndPoint, medID];

    NSURL *url = [NSURL URLWithString:path relativeToURL:[NSURL URLWithString:kInstagramBaseURLString]];

    NSMutableArray *mutableParameterComponents = [NSMutableArray array];
    for (NSString *key in [params allKeys]) {
        NSString *component = [NSString stringWithFormat:@"%@=%@", [key stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding],[[params valueForKey:key] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
        [mutableParameterComponents addObject:component];
    }


    url = [NSURL URLWithString:[[url absoluteString] stringByAppendingFormat:[path rangeOfString:@"?"].location == NSNotFound ? @"?%@" : @"&%@", [mutableParameterComponents componentsJoinedByString:@"&"]]];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
    [request setHTTPMethod:@"POST"];
    [request setAllHTTPHeaderFields:defaultHeaders];

    likeInstagramConnection = [NSURLConnection connectionWithRequest:request delegate:self];

}

It is during this connection that I get the following Error

Error Domain=HTTP Code=400 "HTTP Error" UserInfo=0xd9571b0 {NSLocalizedDescription=HTTP Error} desc <NSHTTPURLResponse: 0xd9574a0> { URL: https://api.instagram.com/v1/media/632580883841234624_257450972/likes?access_token=ACCESS_TOKEN_GOES_HERE } {
    status code: 400, headers {
        Connection = "keep-alive";
        "Content-Language" = en;
        "Content-Length" = 92;
        "Content-Type" = "application/json; charset=utf-8";
        Date = "Tue, 28 Jan 2014 07:17:52 GMT";
        Server = nginx;

        Vary = "Cookie, Accept-Language";
        "X-Ratelimit-Limit" = 5000;
        "X-Ratelimit-Remaining" = 4997;
    }
}

Might be an expired access token. I know in python I am getting this error code in an API call exception, and I can't see why they would make status codes differ between languages. Hope that gets you in the right direction.
