#7 Handle Text and Attachment Messages | Messenger Platform Crash Course For Absolute Beginners

Описание: The last step to build a simple chatbot (with Node.js server and Messenger Platform) is to handle the Text and Attachment messages.We will build a simple Messenger experience that does the following:
1. Parses the message and sender's page-scoped ID from an incoming webhook event.
2. Handles messages and messaging_postbacks webhook events.
3. Sends messages via the Send API.
4. Responds to text messages with a text message.
5. Responds to an image attachment with a generic template that uses the received image.
6. Responds conditionally to a postback payload.

In this tutorial, I will guide you to learn the concepts used in the Messenger Platform, so that in the end, we can build an effective chatbot with this platform.
For each topic, we will be looking into the details, so it will be suitable for beginners.
