Should I pass my APIKEY in every request I do with Retrofit?

Question

I'd like to know the best way to put my APIKEY in all my REST requests withtout having to add it in parameters of the request.

For now I just have a couple of calls, but I'm trying to see further.

@GET(".")
fun getSearch(@Query("s") text: String, @Query("apikey") APIKEY: String) : Observable<ResponseSearch>

I was wondering if there was a way not to have the APIKEY in variables of every call

You can, but the better solution is to use Okhttp Interceptors

Here's an example:

class TokenInterceptor(private val preferencesStorage: SharedPreferencesStorage) : Interceptor {
    override fun intercept(chain: Interceptor.Chain): Response {
        var original = chain.request()
        val token = preferencesStorage.getAccessToken()
        val url = original.url().newBuilder().addQueryParameter("apikey", token).build()
        original = original.newBuilder().url(url).build()
        return chain.proceed(original)
    }
}

You should also add TokenInterceptor to your Okhttp client builder

val client = OkHttpClient.Builder()
            .addInterceptor(TokenInterceptor(SharedPreferencesStorage()))
            .build()
