NSDictionary *customerDictionary = [NSDictionary dictionaryWithObjectsAndKeys:@"blah@blah.com", @"email", @"1", @"facebook", nil];
NSArray *customerArray = [NSArray arrayWithObjects:customerDictionary, nil];
NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:customerArray, @"customers", nil];
NSURLRequest *request = [sharedHTTPClient requestWithMethod:@"POST" path:@"/api/upload" parameters:parameters];
AFJSONRequestOperation *operation =
    [AFJSONRequestOperation JSONRequestOperationWithRequest:request
                                                    success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {}
                                                    failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {}];
[operation start];

On a Node.JS backend, printing out the body shows:

{ customers: [ '1', 'blah@blah.com' ] }

Expected print should be:

{ customers: [{ facebook:'1', email:'blah@blah.com' }] }

What am I doing wrong?

    From the AFNetworking wiki:

    How do I send JSON parameters in my request?

    If you’re using AFHTTPClient, set the parameterEncoding property to
    AFJSONParameterEncoding. Any method on that HTTP client with a
    parameters argument will now encode the passed object into a JSON
    string and set the HTTP body and Content-Type header appropriately.

    Otherwise, you can do this manually by adding the header Content-Type:
    application/json, and setting the body of your request to a JSON
    string.
