### Notes
As mentioned in the video above, you have to install `nodemon` to run the start script. You can install nodemon globally with `npm i -g nodemon` command.

### Send message to group
I was added an example to send a message to groups, but before that we must know the group ID (chat ID). Don't worry, I also add the functionality to help you to get that groups ID.

Here the way to get the groups info (including ID & name):
- Send a message to the API number `!groups`
- The API will replying with the groups info
- Use the ID to send a message
- Here the endpoint: `/send-group-message`
