Retrofit, IGDB Api - How to correctly pass Api Key?

I'm trying to make an query on the internet game database (IGDB) Api using retrofit. In the past, when I used other Api, such as the movie database (TMDB), the api-keys were always passed in as a query, so the interface would look something like this.
#GET("/3/movie/popular")
Call<MovieResults> getPopularMovie(
#Query("api_key") String apiKey,
#Query("language") String language,
#Query("page") int page
);
But with IGDB, I think they want me to pass in the api-key as a Header (I'm not 100% sure, please correct me if I'm wrong). I've never passed an api-key through a header before, so with some guesswork, following is what my interface looks like.
#Headers({
"Accept: application/json",
"user-key: b5bd50####################8b2"
})
#GET("/games")
Call<List<Game>> getGame();
Problem is, when I make the call, although the call ends up in onResponse, the response.body is always null.
So, I ran the code in de-bug mode, and i found this message:
response = Response{protocol=http/1.1, code=401, message=Unauthorized, url=http://v2000.igdb.com/games/}
I don't know what this means, but I am guessing that it isn't recognizing an authorised api-key?
Another interesting anomaly is that, the base url I pass in is:
"https://api-2445582011268.apicast.io/"
I don't know how that ended up being:
http://v2000.igdb.com/
If anyone have any experience with IGDB, please give me some help, will really appreciate it.

I have used this api with JAVA and i can confirm that you should send the API key in the header, so what you have done looks to be correct.
The base url you are getting is also wrong, try using https://api-endpoint.igdb.com/, it is the recommended url.
I can also recommend you to try the api using Postman, it is an excellent tool for testing.
If you are using java you might want to try their java wrapper

How to get SMTP-ID in sendgrid API through json?

How to get SMTP-ID in sendgrid API through json? Example :
In the API tutorial they have mentioned to execute
http(s)://username:password#domain/foo.php
and the result will be (in json):
"email": "john.doe#sendgrid.com",
"timestamp": 1337197600,
"smtp-id": "<4FB4041F.6080505#sendgrid.com>",
"event": "processed"
But actually we need the perfect url to get json.
for eg :
https://sendgrid.com/api/bounces.get.json
for bounce mails
similarly , is there anything to get the above sample json.
Thanks in advance..

If you send an Email to SendGrid through the Web API, you won't have an SMTP-ID. That will be generated by the SendGrid server that translates the API call to an SMTP object. So you're right, the SMTP-ID that comes back in the Event POST isn't helpful.
However, you can add Unique Args to your API call using the x-smtpapi argument in the mail.send call. This will let you define whatever tracking metric(s) you want to the message, and it will all come back on the Event POST.

If you are going to use Unique Args feature, please do remember that they will appear in the most Event notifications but not all of them. Please refer for the details to the sendgrid forum topics which include "missing unique_args" and similar. So, think twice before "building the entire infrastructure" around this feature like some of us did :(

I got my answer .
Actually we can try event API using a callback url, that receives POST request having every details about the email delivered, bounced in json format. Whenever some event is triggered we get a request from Sendgrid. Thats cool.
We can keep these details for further Filtering.
Anyway , thanks jacobmovingfwd

Parsing Facebook api response (JSON) and retrieving the data

I'm a Java Developer and couldn't find many resources to develop facebook apps on Java. Well I'm developing a Facebook app on Java which at some point, reads the inbox of a user. I was able to create a Login flow and get a long term access token. But as I'm very new to the JSON concepts, I could not able to parse the facebook response to get the required data.
I've read some tutorials and got to know basics of JSON and could able to write the code for parsing Simple JSON structures like:
{
"id": 1,
"firstname": "Brad",
"languages": [
{ "lang":"en" , "knowledge":"proficient" },
{ "lang":"fr" , "knowledge":"advanced" },
]
"job":{
"place":"Silicon Valley",
"name":"Microsoft",
} }
But, I was unable to parse the Facebook response as it looks so complex, and I have referred various places for any example or sample code to Parse the Facebook's response for /me/inbox request and couldn't find any.Here I'm looking for any sample code to parse the inbox JSON Object to get the required information for my App. Any effort is highly appreciated. Thank You.
Edit: I'm looking for a sample code in plain JSPs or Servelts.

Spring Social is your friend. Don't get bogged down in integrating with Spring Security (although there are a lot of examples) as the JavaScript login process will be sufficient to get an auth token for the user that you can then query Facebook's API with - just use Spring Social as a library to hide the complexity of the JSON and given you java objects to work with directly.

I ended up having to do it myself. The parent JSON element 'data' contained the data I was looking for. Then I used this tutorial to format it and display it in a Facebook-like way.
I had to actually pick out the data I actually needed. Hope this helps!
You have to use JSONObject and JSONArray, which you can get from getJSONObject() and getJSONArray(). Once you've gotten the JSONObject or JSONArray you need, use getJSONString() to get the desired value.
The tutorial mentioned above is for Android, but the general idea is still there. Let me know if you have any questions. I've done a bit in JSP and Java servlets as well.

How to retrieve home timeline from twitter in the form of .xml or JSON using java?

I want to get a home timeline from twitter and I was able to get the home timeline using twitter4j and oauth authentication method
ConfigurationBuilder confBuilder = new ConfigurationBuilder();
confBuilder.setOAuthAccessToken(accessToken.getToken())
.setOAuthAccessTokenSecret(accessToken.getTokenSecret())
.setOAuthConsumerKey(key)
.setOAuthConsumerSecret(secret);
Twitter twit = new TwitterFactory(confBuilder.build()).getInstance();
User user = twitter.verifyCredentials();
List<Status> statuses = twitter.getHomeTimeline();
but the result is not in the form of .xml or JSON. i also tried
WebResource resource = client.resource("https://api.twitter.com/1/statuses/user_timeline.json");
but all I get is GET https://api.twitter.com/1/statuses/user_timeline.json returned a response status of 401 Unauthorized
I googled many times but I just cant get it right. Please I need a sample java code of how to do it. Complete code that can run right away would be really helpful as I got a lot of partially coded program and just couldnt get it to work. thank you in advance

OK, so after looking at the release notes for the 2.2.x versions, it appears there is a way to get the JSON representation from Twitter4J, but it's disabled by default since it uses some extra memory.
So, you need to:
Enable the JSONStore using the jsonStoreEnabled config option
Get the JSON representation of a request using the getRawJson method
Sorry there's no code example, I haven't tried it myself.

401 Unauthorized:
Authentication credentials were missing or incorrect.
You need to authenticate before you perform the query.

Facebook returns #access_token

I am using Java Scribe + Spring MVC to access Facebook authentication API.
However, the URL with the access token I am getting back from Facebook is in this format:
/facebookCallback#access_token=[long chunk]&expires_in=5028
As you can see, the access_token is preceded by a #, which disallows me from obtaining the access_code as a normal parameter.
Is there any reason why Facebook is appending the # instead of a ?

var hash = document.location.hash;
I think you mean Javascript , and not Java Scribe ?

you are probably using the callback parameter which is designed for the JS library. Make sure you are not sending an incorrect parameter for "type".

Turns out that it probably was caused by my school network. I tried the exact same code both in school and at home and got different results (school - error, home - correct).
The problem solved by itself the next day in school so I won't be able to find out exactly why. Thanks to those who helped.
