Built on Unity's native UnityWebRequest
GET / POST support
Custom headers
Automatic retry system
Single-instance request protection
Optional logging

Installation

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

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();
