Microsoft bot framework And Messanger mobile notification - facebook

Question

I've created a bot with Microsoft bot framework for Messenger.
All work great. i can recieve and send message to messanger but in messanger mobile push notification not work. I omit the property notification_type because facebook guide say
notification_type is optional; by default, messages will be REGULAR
push notification type
It is a Framework bug?
My code:
ConnectorClient connector = new ConnectorClient(new Uri(servUri), microsoftAppId: appId, microsoftAppPassword: pass);
ResourceResponse conversationId = await connector.Conversations.CreateDirectConversationAsync(botAccount, userAccount);
IMessageActivity activity = Activity.CreateMessageActivity();
activity.Id = conversationId.Id;
activity.Type = ActivityTypes.Message;
activity.From = botAccount;
activity.Conversation = conversation;
activity.Recipient = userAccount;
activity.Text = "hello";
await connector.Conversations.SendToConversationAsync((Activity)activity);

I've used activity.ChannelData and all work good
I post my solution, can be useful to someone
Add the attachment to the activity:
activity.ChannelData = new FacebookChannelData()
{
Attachment = GetFacebookAttachment()
};
create the attachment:
private static FacebookAttachment GetFacebookAttachment()
{
return new FacebookAttachment()
{
Payload = new GenericTemplate
{
Elements = new[] {
new TemplateElements(){
Title = "my title",
ItemUrl = "https://example.com",
ImageUrl = "https://example.com/test.jpg",
Subtitle = "subtitle",
Buttons = new[] {
new TemplateButtons() {
Type = "web_url",
Url = "https://example.com",
Title = "button title"
}
}
}
}
}
};
}
and then the classes:
public class FacebookChannelData
{
public FacebookChannelData() {
this.NotificationType = "REGULAR";
}
[JsonProperty("notification_type")]
public string NotificationType { get; set; }
[JsonProperty("attachment")]
public FacebookAttachment Attachment { get; internal set; }
}
public class FacebookAttachment
{
public FacebookAttachment()
{
this.Type = "template";
}
[JsonProperty("type")]
public string Type { get; set; }
[JsonProperty("payload")]
public dynamic Payload { get; set; }
public override string ToString()
{
return this.Payload.ToString();
}
}
public class GenericTemplate
{
public GenericTemplate()
{
this.TemplateType = "generic";
}
[JsonProperty("template_type")]
public string TemplateType { get; set; }
[JsonProperty("elements")]
public TemplateElements[] Elements { get; set; }
}
public class TemplateElements
{
[JsonProperty("title")]
public string Title { get; set; }
[JsonProperty("item_url")]
public string ItemUrl { get; set; }
[JsonProperty("image_url")]
public string ImageUrl { get; set; }
[JsonProperty("subtitle")]
public string Subtitle { get; set; }
[JsonProperty("buttons")]
public TemplateButtons[] Buttons { get; set; }
}
public class TemplateButtons
{
[JsonProperty("type")]
public string Type { get; set; }
[JsonProperty("url")]
public string Url { get; set; }
[JsonProperty("title")]
public string Title { get; set; }
[JsonProperty("payload")]
public string Payload { get; set; }
}

notification_type IS optional - but only in the context of when you're actually specifying a ChannelData on your activity.
So just add (given that you're using Newtonsoft.Json.Linq;)
activity.ChannelData = JObject.FromObject(new
{
notification_type = "REGULAR"
});
and you'll get your notification, provided that your client app has not disabled notifications.
