Hello,

For my custom LucidChart extension, I am actively working on a .NET 8.X C# OAuth 2.0 client to the Lucid REST APIs.  My approach was to create a LucidChartClientBase and then LucidChartUserClient and LucidChartAccountClient that derive from it.

Here is an example of what LucidChartUserClient looks like:
 

    static async Task UserClientStuff()
    {
        var user_client = new LucidChartUserClient(clientId, clientSecret, redirectUri, userScopes);
        await GetAccessTokenAsync(user_client);


        try
        {
            var introspectionResult = await user_client.IntrospectTokenAsync(user_client.TokenDatae"access_token"].ToString());
            Console.WriteLine($"Introspection result: {JsonConvert.SerializeObject(introspectionResult, Formatting.Indented)}");

            var accountInfo = await user_client.GetAccountInfoAsync();
            Console.WriteLine($"User profile: {accountInfo}");

            // Fetch all documents without any filters
            var allDocuments = await user_client.SearchDocumentsAsync();

            // Process the list of documents as needed
            foreach (var document in allDocuments.Where(x => x.Title == "DanFlowchart1"))
            {
                Console.WriteLine($"Document ID: {document.DocumentId}, Title: {document.Title}");

                string documentId = document.DocumentId;
                var documentContents = await user_client.GetDocumentContentsAsync(documentId);

                Console.WriteLine($"Document Title: {documentContents.Title}");
                foreach (var page in documentContents.Pages)
                {
                    Console.WriteLine($"Page Title: {page.Title}");
                    foreach (var shape in page.Items.Shapes)
                    {
                        Console.WriteLine($"Shape ID: {shape.Id}, Class: {shape.Class}");
                    }
                }
            }

        }
        catch (Exception ex)
        {
            Console.WriteLine($"Error during token introspection: {ex.Message}");
        }

    }

Essentially, I have created a bunch of C# classes such as Document, DocumentContent, Shape, Items, etc.  I would love to hear from other Lucid package creators to see if there would be interest in this code and collaborating.  Let me know. 

Thanks, Dan
