Go to the admin area of Chat24Plus, then go to Settings > Apps > Telegram, and enter the Envato purchase code to install and activate the app. If you have the cloud version, the app is already active.
If you have already created a Telegram bot in the past, type the command `/mybots` and open your bot, then click API token.
If you have never created a Telegram bot before, type the command `/newbot` to create a new bot. The BotFather will ask you for a name and username; enter them and it will generate an authentication token. More details at https://core.telegram.org/bots.
Copy the token and paste it into Chat24Plus > Telegram > Token, then click Synchronize now. Your website must use HTTPS (SSL certificate); HTTP is not supported.
You're done. All messages sent to your Telegram bot will appear in the conversation admin area of Chat24Plus.
