How can I use the Chatbot platform on a local server?

Why do I have to develop chatbots locally?

As a developer, you probably don’t always have a server with a public IP address and DNS name available. In order to develop and test chatbots locally, a port forwarding service is needed. The Forward-Service ensures that the local test environment (e.g. virtual machine behind a firewall or without a public IP address) is accessible from the Internet and therefore globally visible.

Why do I need a port forwarding service to receive instant messages?

Most instant messengers use WebHooks for communication and push events (e.g. new text message or video from user, message was read etc.). A WebHook is a HTTP callback of the messenger service to inform the receiver (in this case the Business Bot Platform) about events, i.e. when something happens. The Forward-Service must forward the HTTP requests to the local server so that Business Bot Platform and thus Chatbot know about these events.

How does it work in detail?

The Forward-Service has an official DNS name and a public IP address, e.g. https://myname.forward-server.com/. This URL is then configured in the Messenger service (e.g. Telegram) for all events. As soon as an event occurs, the Messenger service sends the request to the Forward-Service. The Forward-Service then passes the request (unchanged) to the local server (localhost) via a tunnel. The following graphic illustrates this concept.

By means of Forward-Services, you can develop chatbots faster and test them more efficiently. Some providers offer the basic functionalities (HTTP/TCP tunneling) free of charge.
