Missing support for OrganizationID and ProjectID

[egable]

When I generate an API key, it requires me to use an OrganizationID and ProjectID in conjunction with the API key. There appears to be no mechanism to specify these when creating a client.

Thank you for drawing attention to this, @egable! We'll look into adding this to the client options type (which would be the closest parallel to client instantiation in node/python) as soon as possible.

In the interim, although it's substantially more code, you could use a custom System.ClientModel PipelinePolicy to manually add these or other headers; below is a standalone code example demonstrating that approach.

using OpenAI;
using OpenAI.Chat;
using System.ClientModel.Primitives;

#nullable disable

public class AddAuthHeadersPolicy : PipelinePolicy
{
    public string OrganizationId { get; set; }
    public string ProjectId { get; set; }

    public override void Process(PipelineMessage message, IReadOnlyList<PipelinePolicy> pipeline, int currentIndex)
    {
        ApplyHeaders(message?.Request?.Headers);
        ProcessNext(message, pipeline, currentIndex);
    }

    public override ValueTask ProcessAsync(PipelineMessage message, IReadOnlyList<PipelinePolicy> pipeline, int currentIndex)
    {
        ApplyHeaders(message?.Request?.Headers);
        return ProcessNextAsync(message, pipeline, currentIndex);
    }

    private void ApplyHeaders(PipelineRequestHeaders headers)
    {
        if (headers is null)
        {
            return;
        }
        if (!string.IsNullOrEmpty(OrganizationId))
        {
            headers.Set("OpenAI-Organization", OrganizationId);
        }
        if (!string.IsNullOrEmpty(ProjectId))
        {
            headers.Set("OpenAI-Project", ProjectId);
        }
    }
}

public static class Program
{
    public static void Main(string[] args)
    {
        AddAuthHeadersPolicy authHeadersPolicy = new()
        {
            ProjectId = "your project ID",
        };
        OpenAIClientOptions clientOptions = new();
        clientOptions.AddPolicy(authHeadersPolicy, PipelinePosition.BeforeTransport);

        ChatClient client = new("gpt-4o", clientOptions);
    }
}
