Android-REST API request :can't read custom header parameters in server

I'm trying to get response from a node.js rest server (reverse proxy with nginx).
When i try the API through postman, I'm able to read the header parameters in server. But when testing it in Android device, I get the following error:
header undefined
here is the custom header key name
my_basic_key

OkHTTP how to replace team_number from url POST

I have url like this.
http://host/parallel/team/:team_number.json
and it has post params.
like team_number, team_name.
How to make a post request such that i replace team_number to team number with a value.
Does :team_number need to be handled differently ?
So far i have done
RequestBody formBody = new FormBody.Builder()
.addEncoded(TEAM_NUMBER,tracking_number)
.add(TRACK_NAME, name)
.build();
Request request = new Request.Builder()
.url(SEND_TRACKING_DATA)
.post(formBody)
.build();
Response response = CoreApplication.okHttpClient.newCall(request).execute();
return response.body().string();

404 error with POST and OkHttp3

I'm having an issue posting data to the Challonge API with OkHttp3 on Android... This is the jist of my code:
OkHttpClient client = new OkHttpClient();
HttpUrl.Builder urlBuilder = new HttpUrl.Builder();
urlBuilder = HttpUrl.parse("https://api.challonge.com/v1/tournaments/"+EVENT_ID+".json")
.newBuilder();
RequestBody postBody = new FormBody.Builder()
.add("_method", "post")
.add("api_key", API_KEY)
.add("participant[name]", name.getText().toString())
.add("participant[misc]", forum_id.getText().toString())
.build();
Request request = new Request.Builder()
.url(urlBuilder.build().toString())
.post(postBody)
.build();
Response response = client.newCall(request).execute();
No matter what I do, the resulting reponse is a 404 page.
If I do a GET response to the same URL, I get a proper response. However, the moment I add .post(postBody) to the request, its immediately 404s.
The documentation for the Challonge API is here:
http://api.challonge.com/v1/documents/participants/create

It looks to me like you're just using the wrong URL. The URL you've got there, "https://api.challonge.com/v1/tournaments/"+EVENT_ID+".json", is the URL for retrieving a single tournament, as seen here. This link was meant to receive GET requests.
According to the link you provided, you should alter your code to POST to https://api.challonge.com/v1/tournaments/"+EVENT_ID+"/participants.json

Correct syntax for adding parameters to get() and post() request using okhttp in Android

What I want to achieve ?
I am trying to send two parameters in my Server URL using OkHttp through both get and post bcoz i want to know the syntax for both the methods.
What I had Tried ?
I have searched SO for questions on OkHttp but those had not solved my IllegalArgumentException.
I have seen below links :
Add query params to a GET request in okhttp in Android
and this
How to add parameters to api (http post) using okhttp library in Android
and
How to add query parameters to a HTTP GET request by OkHttp?
Exception from code 2:
Code I had used till now :
1)GET
urls = chain.request().httpUrl() <-- NullPointerException Line
.newBuilder()
.scheme("http")
.host(SERVER_IP)
.addQueryParameter("from", valueFrom)
.addQueryParameter("to",valueTo)
.build();
request = chain.request().newBuilder().url(urls).build();
response = chain.proceed(request);
2)GET
urls =new HttpUrl.Builder()
.host(SERVER_IP) <--- IllegalArgumentException line
.addQueryParameter("from", valueFrom)
.addQueryParameter("to", valueTo)
.build();
request = new Request.Builder().url(urls).build();
response = client.newCall(request).execute();
3)POST
body = new
MultipartBuilder().type(MultipartBuilder.FORM).addFormDataPart("from",
valueFrom).addFormDataPart("to",valueTo).build();
Log.i("Body data",""+body.toString());
request = new Request.Builder().url(params[0]).post(body).build();
Log.i("Request data",""+request.toString());
response = client.newCall(request).execute();
4)POST
body = new FormEncodingBuilder().add("from", valueFrom).add("to",
valueTo).build();
Log.i("Body data",""+body.toString());
request = new Request.Builder().url(params[0]).post(body).build();
Log.i("Request data",""+request.toString());
response = client.newCall(request).execute();
build.gradle
dependencies
{
compile files('libs/okhttp-2.5.0.jar')
compile files('libs/okio-1.6.0.jar')
}
Thanks In Advance...
Edit :
The above code for POST request is working fine now
But for GET request I still have no solution.

Just set your GET parameter extend your URL:
RequestBody body = new FormEncodingBuilder()
.add("requestParamName", requestParameter.getRequestParams())
.build();
Request request = new Request.Builder()
.url("https://www.test.com/serviceTest?parama=abc&paramb=123")
.post(body)
.build();
