Production-ready service templates.
Flutter (Dart)
Hardened service class.
`api_service.dart`
dart
import 'package:http/http.dart' as http;
import 'dart:convert';
class DsiApiService {
static const String baseUrl = "https://fake-api.devsecit.com/1.0.0/wb/";
static Future call({required String method, required String table, Map? data}) async {

Hook and Server blueprints.
Server API Bridge
typescript
'use server'
export async function dsiRequest(method: string, table: string, data: any = {}) {
const token = Buffer.from("PgcQqi8ZGmlnYwd50JKo74_secure_token_2024").toString('base64');
const ts = Buffer.from(Math.floor(Date.now() / 1000).toString()).toString('base64');
const res = await fetch("https://fake-api.devsecit.com/1.0.0/wb/", {
method: 'POST',
body: new URLSearchParams({ token, timestmp: ts, method, table, ...data })
});
return res.json();
}C# (.NET)
Modern HttpClient implementation.
`DsiClient.cs`
csharp
using System;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;
using System.Collections.Generic;
public class DsiClient {
private static readonly HttpClient client = new HttpClient();
private const string BaseUrl = "https://fake-api.devsecit.com/1.0.0/wb/";
private const string AppToken = "PgcQqi8ZGmlnYwd50JKo74_secure_token_2024";
public async Task CallApi(string method, string table, Dictionary extraData = null) {
var token = Convert.ToBase64String(Encoding.UTF8.GetBytes(AppToken));
var ts = Convert.ToBase64String(Encoding.UTF8.GetBytes(DateTimeOffset.UtcNow.ToUnixTimeSeconds().ToString()));
var payload = new Dictionary {
{ "token", token },
{ "timestmp", ts },
{ "method", method },
{ "table", table }
};
if (extraData != null) foreach (var kv in extraData) payload[kv.Key] = kv.Value;
var content = new FormUrlEncodedContent(payload);
client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", "YOUR_SECRET");
var response = await client.PostAsync(BaseUrl, content);
return await response.Content.ReadAsStringAsync();
}
} Java (Android)
Production OkHttp implementation.
`DsiApiService.java`
java
import android.util.Base64;
import okhttp3.*;
import java.io.IOException;
public class DsiApiService {
private static final String BASE_URL = "https://fake-api.devsecit.com/1.0.0/wb/";
private final OkHttpClient client = new OkHttpClient();
public void call(String method, String table, FormBody extraParams, Callback callback) {
String token = Base64.encodeToString("PgcQqi8ZGmlnYwd50JKo74_secure_token_2024".getBytes(), Base64.NO_WRAP);
String ts = Base64.encodeToString(String.valueOf(System.currentTimeMillis() / 1000).getBytes(), Base64.NO_WRAP);
FormBody.Builder bodyBuilder = new FormBody.Builder()
.add("token", token)
.add("timestmp", ts)
.add("method", method)
.add("table", table);
// Add extra params if needed logic here...
Request request = new Request.Builder()
.url(BASE_URL)
.addHeader("Authorization", "Bearer YOUR_SECRET")
.post(bodyBuilder.build())
.build();
client.newCall(request).enqueue(callback);
}
}Kotlin (Android/KMP)
Modern Ktor Client blueprint.

append("token", token)
append("timestmp", ts)

}React Native
Universal Fetch implementation.
`useDsiApi.js`
javascript
import { Buffer } from 'buffer';
export const dsiRequest = async (method, table, data = {}) => {

const body = new URLSearchParams({
token,
timestmp: ts,
method,
table,
...data
}).toString();
const response = await fetch("https://fake-api.devsecit.com/1.0.0/wb/", {
method: 'POST',
headers: {
'Authorization': 'Bearer YOUR_SECRET',
'Content-Type': 'application/x-www-form-urlencoded'
