@spadillez Hi, on my side I have no issue with the invalid request URI. Have you initialized the WhatsApp client in your controller class with dependency injection?

[spadillez]

Yes

      public WhatsappController(
            TipoSolicitacaoService tipoSolicitacaoService,
            UrgenciaSolicitacaoService urgenciaSolicitacaoService,
            SolicitacaoUsuarioService solicitacaoUsuarioService,
            UsuarioServico usuarioService,
            IWhatsAppBusinessClient whatsAppBusinessClient)
        {
            _tipoSolicitacaoService = tipoSolicitacaoService;
            _urgenciaSolicitacaoService = urgenciaSolicitacaoService;
            _solicitacaoUsuarioService = solicitacaoUsuarioService;
            _usuarioService = usuarioService;
            _whatsAppBusinessClient = whatsAppBusinessClient;
        }

You can send me a sample repo without the credentials so I can have a look what is happening with the request URI on your end.

[spadillez]

Yes, i have find a way to get it work, using the legacy injection

`WhatsAppBusinessCloudApiConfig whatsAppConfig = new WhatsAppBusinessCloudApiConfig(); whatsAppConfig.WhatsAppBusinessPhoneNumberId = configuration.GetSection("WhatsAppBusinessCloudApiConfiguration")["WhatsAppBusinessPhoneNumberId"]; whatsAppConfig.WhatsAppBusinessAccountId = configuration.GetSection("WhatsAppBusinessCloudApiConfiguration")["WhatsAppBusinessAccountId"]; whatsAppConfig.WhatsAppBusinessId = configuration.GetSection("WhatsAppBusinessCloudApiConfiguration")["WhatsAppBusinessId"]; whatsAppConfig.AccessToken = configuration.GetSection("WhatsAppBusinessCloudApiConfiguration")["AccessToken"];

        var httpClient = new HttpClient();

        httpClient.BaseAddress = WhatsAppBusinessRequestEndpoint.BaseAddress;

        //create Mpesa API client instance
        _whatsAppBusinessClient = new WhatsAppBusinessClient(httpClient, whatsAppConfig);`

Tried to find why the httpclient got without the base url when using the DInjection but without success i will make a sample for you. But atleast it worked for now

[gabrieldwight]

Alright. I will investigate further the NET 6 builder for httpclient why it is not setting up the base url.
