Plugin API

Official library for building ChatAIze chatbot add-ons.

First Steps

1. Install the latest version of the .NET 9.0 SDK - https://dotnet.microsoft.com/en-us/download/dotnet/9.0.
2. Create a new C# Class Library project.
3. Install ChatAIze.PluginApi NuGet package.
4. Create a class that implements the IPluginLoader interface from the ChatAIze.Abstractions.Plugins namespace. Alternatively, you can implement the IAsyncPluginLoader interface for asynchronous loading.
5. In the Load method (or LoadAsync), construct and return a new instance of the ChatbotPlugin class with the specified Id and Title.
6. Add settings, functions, conditions, and actions to your plugin: plugin.AddStringSetting() , plugin.AddFunction(), plugin.AddCondition(), plugin.AddAction(), etc.
7. Build the project in Release configuration to generate a DLL file.
8. Upload the generated DLL file from the chatbot dashboard: Integrations > Manage Plugins > Upload.
9. The chatbot will automatically load the plugin, and its functionality should be available immediately.
10. Verify that the plugin is listed under: Integrations > Manage Plugins.

Installation

.NET CLI

dotnet add package ChatAIze.PluginAPI

Package Manager Console

Install-Package ChatAIze.PluginAPI

Plugin Base

The Load and LoadAsync methods are called automatically when the chatbot server starts or when the plugin is uploaded via the dashboard.

Synchronous Loader

using ChatAIze.Abstractions.Plugins;
using ChatAIze.PluginApi;

namespace ExamplePlugin;

public class ExamplePluginLoader : IPluginLoader
{
    public IChatbotPlugin Load()
    {
        var plugin = new ChatbotPlugin
        {
            Id = "com.example.plugin",
            Title = "Example Plugin"
        };

        return plugin;
    }
}

Asynchronous Loader

using ChatAIze.Abstractions.Plugins;
using ChatAIze.PluginApi;

namespace ExamplePlugin;

public class ExamplePluginLoader : IAsyncPluginLoader
{
    public async ValueTask<IChatbotPlugin> LoadAsync(CancellationToken cancellationToken = default)
    {
        await Task.Delay(1000, cancellationToken); // Simulate some async work

        var plugin = new ChatbotPlugin
        {
            Id = "com.example.plugin",
            Title = "Example Plugin"
        };

        return plugin;
    }
}

Functions

All functions added to the plugin are discoverable by the chatbot and can be called on-demand during conversations. Start by writing a normal C# method, then register it with the plugin using plugin.AddFunction().

• Function names must be unique across all loaded plugins.
• Asynchronous functions and cancellation tokens are supported.
• It is recommended to use simple parameter and return types (string, int, bool, etc.) or custom classes with primitive properties.
• Returned objects are serialized to JSON and visible to the chatbot.
• You can optionally add IFunctionContext parameter to access conversation details, user info, plugin settings, and more.

using ChatAIze.Abstractions.Chat;
using ChatAIze.Abstractions.Plugins;
using ChatAIze.PluginApi;

namespace ExamplePlugin;

public class ExamplePluginLoader : IPluginLoader
{
    private readonly HttpClient _httpClient = new();

    public IChatbotPlugin Load()
    {
        var plugin = new ChatbotPlugin
        {
            Id = "exampleplugin",
            Title = "Example Plugin",
        };

        plugin.AddFunction(GetDogPhoto);
        return plugin;
    }

    public async Task<string> GetDogPhoto(IFunctionContext context, CancellationToken cancellationToken = default)
    {
        if (context.User.Email is null || !context.User.Email.EndsWith("@example.com", StringComparison.OrdinalIgnoreCase))
        {
            return "You cannot use this function.";
        }

        if (context.IsPreview || context.IsDebugModeOn || context.IsCommunicationSandboxed)
        {
            return "Testing...";
        }

        var response = await _httpClient.GetStringAsync("https://dog.ceo/api/breeds/image/random", cancellationToken);
        return response;
    }
