how to get back the “payload” of the button “ Get Started ” in c#

Question

I work with Microsoft Bot Framework in Messenger and I would like to know how to get back the "payload" of the "Get Started" button. Which function I should create in C#?

Answer 1

You don't have to - the payload is returned as a regular message, so you can just use this:

if (activity.ChannelId == "facebook" && activity.Text == "GET_STARTED_PAYLOAD")
{
   // etc

Note that the documentation lists some restrictions on this feature :

• The welcome screen is only shown the first time the user interacts with the Page on Messenger.
• Only admins, developers, and testers of the app can see it when the app is in development mode.
• Your app must be subscribed to postback webook events.
