DifySDK

Native AOT-compatible Refit interfaces and source-generated System.Text.Json metadata for the Dify API.

For dependency-injection registration and API-key authentication, install DifySDK.Extensions.

Install

dotnet add package DifySDK

Create a client directly

using System.Net.Http.Headers;
using System.Text.Json;
using DifySDK.Chats;
using DifySDK.Models;
using DifySDK.Serialization;
using Refit;

var httpClient = new HttpClient
{
    BaseAddress = new Uri("https://api.dify.ai/v1/")
};
httpClient.DefaultRequestHeaders.Authorization =
    new AuthenticationHeaderValue("Bearer", "app-your-api-key");

var settings = new RefitSettings(
    new SystemTextJsonContentSerializer(new JsonSerializerOptions(JsonSerializerDefaults.Web)
    {
        TypeInfoResolver = DifyJsonSerializerContext.Default
    }));

var chat = RestService.For<IDifyChatApi>(httpClient, settings);
var response = await chat.SendAsync(new ChatMessageRequest
{
    Query = "What can you do?",
    User = "user-123",
    InputValues = new Dictionary<string, object?>
    {
        ["language"] = "en"
    }
});

Console.WriteLine(response.Answer);

InputValues lets callers use ordinary .NET values. The SDK converts them to the Dictionary<string, JsonElement> shape required by Dify without reflection, which is suitable for Native AOT.

Consume streaming responses

Use the IAsyncEnumerable<DifyStreamEvent> extension for all supported SSE endpoints.

using DifySDK.Chats;
using DifySDK.Models;
using DifySDK.Streaming;

await foreach (var streamEvent in chat.StreamAsync(new ChatMessageRequest
{
    Query = "Write a haiku about APIs",
    User = "user-123"
}))
{
    if (streamEvent is DifyMessageStreamEvent message)
        Console.Write(message.Answer);

    if (streamEvent is DifyErrorStreamEvent error)
        Console.Error.WriteLine(error.Message);
}

The same pattern is available for completions, workflows, workflow event reconnection, knowledge-base pipeline runs, and datasource-node runs.
