Microsoft Bot Framework channel integration: more endpoints?

Question

I'm using Microsoft Bot Framework using the channel registration product and the REST API. I have setup the "messaging endpoint" and everything works fine for sending and receiving messages.

But I don't just want to send/receive messages. Something as simple as setting up a welcome message seems impossible because my endpoint receives nothing other than messaging events (when the bot is in the channel / conversation.)

Is there something I have missed?

I would like to setup several endpoints, or use the same, whatever, to listen to other types of events.

sorry but your question is unclear. If your problem is about sending a welcome message to users, please add more details about the channel you are using, add your MessagesController code, etc. If it's something else, edit your question — Nicolas R
What are you trying to accomplish here exactly and how is it a coding problem? Please share your code. What did you try, what worked? What didn't work? — nilsw
There is no code to share. The issue is that when setting up MBF using the "channel" integration product, it seems like the only available endpoint (that receives HTTP requests from MBF) I am able to set up only listens to messages received by the bot. This is set up directly in the MBF console. I am wondering if there is an API or configuration I have missed, that would allow me to receive event types other than messaging events. — Konrad
Note that this is using the REST API (or websocket) only, NOT using the node.js SDK for instance. — Konrad

You need to implement in the MessageController something like these: Pay attention in the else if. The funcition in the controller is HandleSystemMessage.

else if (message.Type == ActivityTypes.ConversationUpdate) {

            // Handle conversation state changes, like members being added and removed
            // Use Activity.MembersAdded and Activity.MembersRemoved and Activity.Action for info
            // Not available in all channels
            IConversationUpdateActivity update = message;
            var cliente = new ConnectorClient(new System.Uri(message.ServiceUrl), new MicrosoftAppCredentials());

            if (update.MembersAdded != null && update.MembersAdded.Count > 0)
            {
                foreach(var member in update.MembersAdded)
                {
                    if(member.Id != message.Recipient.Id)
                    {
                        //var username = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
                        var username = message.From.Name;
                        var reply = message.CreateReply();
                        //string dir = System.AppDomain.CurrentDomain.BaseDirectory + "Images" + Path.DirectorySeparatorChar + "cajamar.png";
                        string dir = HttpRuntime.AppDomainAppPath + "Images" + Path.DirectorySeparatorChar + "cajamar.png";

                        reply.Attachments.Add(new Attachment(
                                contentUrl: dir,
                                contentType: "image/png",
                                name: "cajamar.png"
                            ));
                        reply.Text = $"Bienvenido {username} al ChatBot de convenios:";
                        cliente.Conversations.ReplyToActivity(reply);
                        //var reply = message.CreateReply();

                        //reply.Text = $"El directorio base es: {HttpRuntime.AppDomainAppPath}";
                        //cliente.Conversations.ReplyToActivityAsync(reply);
                    }
                }
            }
        }
