JSON Multiple urls with the headers

I am trying to have multiple urls in $.ajax https://api.twitch.tv/kraken/channels/ and https://api.twitch.tv/kraken/streams/
$.ajax({
type: 'GET',
url: 'https://api.twitch.tv/kraken/channels/' + item,
headers:{
'Client-ID': 'k7uj51l1cteh0sbhwplk4hqq6c7bqo'},
success: function(data){
console.log(data);
},
error: function(data){
alert("doesn't work")
},
});
but I also need to have headers with 'Client-ID'. I was trying with this:
$.getJSON(channel, function(e){
$.getJSON(stream,function(f){
});
});
but it doesn't work.

it seems you forgot to add one more header "accept": "application/vnd.twitchtv.v5+json"
The complete working code example
var settings = {
"async": true,
"crossDomain": true,
"url": "https://api.twitch.tv/kraken/channels/44322889",
"method": "GET",
"headers": {
"client-id": "k7uj51l1cteh0sbhwplk4hqq6c7bqo",
"accept": "application/vnd.twitchtv.v5+json"
}
}
$.ajax(settings).done(function (response) {
console.log(response);
});

JSON ajax post data - get 400 bad request message

First of all. I read many questions about this problem here in stackoverflow but nothing helps me.
I've this function:
function ip_login(){
//alert(JSON.stringify(arr_login));
$.ajax({
crossdomain: true,
url: 'https://****/Token',
type: 'POST',
data: JSON.stringify(arr_login),
contentType: 'application/x-www-form-urlencoded',
dataType: 'json',
success: function (data) {
console.log(data);
}
});
}
And this is my JSON string:
{"grant_type":"password","username":"mail#mail.de","password":"blabla"}
With the google chrome extension 'postman' it works fine!
If I test my code above I got the popular 400 bad request message.
When I take the code of the extension 'postman' it doesn't work too.
This is the code of postman:
var settings = {
"async": true,
"crossDomain": true,
"url": "https://*****/Token",
"method": "POST",
"headers": {
"cache-control": "no-cache",
"content-type": "application/x-www-form-urlencoded"
},
"data": {
"grant_type": "password",
"username": "mail#mail.de",
"password": "blabla"
}
}
$.ajax(settings).done(function (response) {
console.log(response);
});
I can't fine my issue..
I searched on Google and SO but no reply helped me.
Edit:
This is in my console:
"NetworkError: 400 Bad Request - https://awesome-url.de/Token"

The problem is in stringifiing JSON. Server expects json but you send string(stringified JSON). Try
function ip_login(){
//alert(JSON.stringify(arr_login));
$.ajax({
crossdomain: true,
url: 'https://****/Token',
type: 'POST',
data: arr_login,
contentType: 'application/x-www-form-urlencoded',
dataType: 'json',
success: function (data) {
console.log(data);
}
});
}

Not sure if this helps, but try anyways.
When I'm sending Json, I didn't use "JSON.stringify(arr_login)"
All I did was something like "data:{arr_login:arr_login}"
This is how my variable looks like.
var req = new Object();
req["type"] = 'refresh';
req["time"] = window.page_ordertime;
This is how my ajax looks like
$.ajax( {
url:"listorder_process.php",
method: "POST",
dataType:"json",
data:{request:req}
} )

AJAX post is empty on the server side (PHP)

I am making an AJAX request to a PHP controller, by using jQuery ajax, but when trying to get the posted data with PHP the $_POST is empty. Below is the actual function:
function GetSeriesForManufacturer(manuf) {
selectedmanufacturer = manuf;
//Make an AJax Call For Getting Series Of Manufacturer
var series = null;
$.ajax({
type: "POST",
url: url,
data: "{manufacturer:'" + selectedmanufacturer + "'}",
contentType: "application/json", //; charset=utf-8",
dataType: "json",
cache: false,
async: false,
success: function (response) {
//remove loading gif
$(".loading").hide();
//Append Data
AppendSeries($.parseJSON(response.text), selectedmanufacturer);
//Custom Scrollbar Call
$('.MatchingSeries ul').mCustomScrollbar();
},
error: function (XMLHttpRequest, textStatus, errorThrown) { }
});
}
Thanks in advance!

First, you don't need to stringify data. Just send object literal is ok.
data: {manufacturer: selectedmanufacturer},
Second, you don't need this line:
contentType: "application/json",

Let jQuery do the encoding for you:
$.ajax({
type: "POST",
url: url,
data: {
manufacturer: selectedmanufacturer
},
contentType: "application/json", //; charset=utf-8",
dataType: "json",
cache: false,
async: false,
success: function (response) {
...
},
error: function (XMLHttpRequest, textStatus, errorThrown) { }});
