what does the colon mean in the Twitter API Resource URL format? -

the twitter api retweeting shows resource url following:

http://api.twitter.com/1/statuses/retweet/:id.format

and says "id" required parameter.

so based on thought following aifnetworking call work. set: postpath:@"1.1/statuses/retweet.json"

and parameters: nsmutabledictionary *params = [nsmutabledictionary dictionarywithdictionary:@{@"id": tweetid}];

and entire call looks like:

- (void)postaretweet:(nsstring*)tweetid success:(void (^)(afhttprequestoperation *operation, id response))success failure:(void (^)(afhttprequestoperation *operation, nserror *error))failure {  nsmutabledictionary *params = [nsmutabledictionary dictionarywithdictionary:@{@"id": tweetid}]; self postpath:@"1.1/statuses/retweet.json" parameters:params success:success failure:failure];} 

but got 404 error telling me page didn't exist. after trial , error, forced postpath

postpath:@"1.1/statuses/retweet/@"some_tweet_number".json" 

and worked.

so not understand why "params" entry "id" key did not appended original postpath supposed . thought perhaps postpath has include "id" , in addition same "id" parameter.

so :id mean in resource url?? why api required "id" of tweet part of url path , in addition passed parameter? seems redundant.

let's want retweet tweet id of 123456. number :id.

now, let's want response in xml. that's format.

so can have

https://api.twitter.com/1.1/statuses/retweet/123456.xml 

or

https://api.twitter.com/1.1/statuses/retweet/123456.json 

do note api has changed version 1.1. should read documentation @ https://api.twitter.com/1.1/

for retweet documentation, see https://dev.twitter.com/docs/api/1.1/post/statuses/retweet/%3aid
