Vangogh - Simple WebRequest System for Unity

Vangogh is a lightweight and fluent HTTP request helper for Unity built on top of UnityWebRequest.
It focuses on minimal syntax, chainable configuration, and simple async workflows using coroutines.

Project by NyanHeavy Studios
Inspired by Davinci by Shamsdev.

Features

• Simple fluent builder syntax
• Built on Unity's native UnityWebRequest
• GET / POST support
• Custom headers
• Automatic retry system
• Single-instance request protection
• Optional logging
• Callback-based results
• Coroutine-based async execution
• No external dependencies

Installation

1. Copy Vangogh.cs into your Unity project (recommended folder):

Assets/
  Scripts/
    Vangogh/
      Vangogh.cs

2. Unity will compile automatically.

No additional setup is required.

Basic Usage

Simple GET

using NyanHeavyStudios.Vangogh;

Vangogh.GET("https://api.example.com/data")
    .OnResult(res =>
    {
        Debug.Log(res.result);
    })
    .Init();

Simple POST

Vangogh.POST("https://api.example.com/login")
    .SetBody("{\"user\":\"admin\",\"password\":\"123\"}")
    .OnResult(res =>
    {
        Debug.Log(res.result);
    })
    .Init();

Full Example

Vangogh.POST("https://api.example.com/data")
    .SetBody("{\"value\":10}")
    .SetContentType("application/json")
    .AddHeader("Authorization", "Bearer TOKEN")
    .SetAttempts(3, 1f)
    .SetLog(true)
    .UseSingleInstance()
    .OnStart(() => Debug.Log("Request started"))
    .OnSuccess(() => Debug.Log("Success"))
    .OnError(() => Debug.Log("Error"))
    .OnEnd(() => Debug.Log("Finished"))
    .OnResult(res =>
    {
        Debug.Log(res.code);
        Debug.Log(res.result);
    })
    .Init();
