Hi André , please make reference to this forum post that provides information on how access a language cloud resource from Trados Studio automation:  RE: Programmatically Pre-translate a Project with Language Weaver as a MT resource 

Example automation project: github.com/.../StandAloneConsoleApp_PretranslateUsingProvider

Hi Patrick,

thanks for the reference to the other post.

I tried it, but I still get "Authentication failed".

The example in the other post is kind of strange. I added the credentials (API Key) and later in the code a authentication via Client ID is done. I would expect, that API Key should be enough. Authentication via Client ID is working. The token will be returned.

This is basically the code. Maybe I overlooked something.

        public void Create()
        {
            // Load Template
            ProjectTemplateReference template = new ProjectTemplateReference(_templateFile);

            // New template based project
            FileBasedProject newProject = new FileBasedProject(this.GetInfoForTemplateProject(), template);
            Console.Clear();

            // Add credentials

            // Update this variable with the actual URI of the translation provider.
            // You can retrieve this value from an existing project or project template (.sdlproj/.sdltpl).
            // To do this, open the project file in a text editor of your choice.
            // Look for the XML element <CascadeEntryProvider> and its child elements.
            // These elements should contain the URI for the translation provider.
            //
            // For example:
            // - URIs starting with "languagecloud.translation.https://" indicate a Translation Engine.
            //
            // Copy the complete URI from the project/template file and assign it to the variable below.
            //
            // Example URI: 
            // If a project template is used, you would typically need to map the URI from the project template file to the actual URI.
            // For the sake of this example, change this value with the actual tpUri string.
            // This is because, when the project automation api is used, the credentials need to be provided explicitly as it works outside the context of Trados Studio.
            var tpUriString = @"languagecloud.translation.https://671a3cbd5ba2d5774df8cd41/?"; // Paste URI here

            // The API key can be obtained from the Language Cloud web interface.
            // Navigate to: Users -> Integrations -> API Keys.
            // Copy the API key from this section.
            var apiKey = "<removed>"; // Paste the API Key here

            //if (string.IsNullOrEmpty(templatePath))
            //{
            //    var tpConfig = newProject.GetTranslationProviderConfiguration();

            //    var tpReference = new TranslationProviderReference(new Uri(tpUriString), null, true);
            //    var tpCascadeEntry = new TranslationProviderCascadeEntry(tpReference, true, true, false);
            //    tpConfig.Entries.Add(tpCascadeEntry);
            //    newProject.UpdateTranslationProviderConfiguration(tpConfig);
            //}

            newProject.Credentials.AddCredential(new Uri(tpUriString), apiKey);
            newProject.Save();

            //Console.WriteLine("Adding source files to the SDL project...");
            // Add files to project
            this.AddFiles(newProject, _filesWithPm);
            newProject.Save();

            ProjectFile[] projectFiles = newProject.GetSourceLanguageFiles();

            //Console.WriteLine("Adding Perfect Match files to the SDL project...");
            // Add Perfect Match files
            this.AddPerfectMatchFiles(newProject, projectFiles);

            //Login to LC for projects with Translation Engine providers 
            var lcService = new LcService();
            lcService.LoginToLC();

            // Run Tasks
            newProject.RunAutomaticTask(projectFiles.GetIds(), AutomaticTaskTemplateIds.Scan);

            // Process
            CreateProject(newProject, projectFiles);

            // Save Project
            newProject.Save();

            // Get amount of words that needs to be translated
            _sdlp.Words = GetProjectStatistics(newProject);

            // Open Project
            if (_autoOpen)
                Process.Start(newProject.FilePath);
