sends a message to a discord channel via a bot using command line HTTP POST- curl

discord-bot-post-message.sh

#!/bin/bash

# update the TOKEN and the CHANNELID, rest is optional
# you may need to connect with a websocket the first time you run the bot
#   use a library like discord.py to do so

curl -v \
-H "Authorization: Bot TOKEN" \
-H "User-Agent: myBotThing (http://some.url, v0.1)" \
-H "Content-Type: application/json" \
-X POST \
-d '{"content":"Posting as a bot"}' \

Thanks for the script.

A way to get the channel URL is to create and use a discord's webhook:

• go to (your) Server settings, then Webhooks
• create a new webhook
• copy/paste the webhook URL into the script
  (the URL looks like: https://discordapp.com/api/webhooks/162930455b6v7s8b9jjvsabcvkbvsnmNI1GvxKjO5JH)
  no need of websocket or whatever another authentication

How i get the channel id url?

@k1msho In The Discord application go to Settings > Appearance > Check developer mode. Right click channel name and copy the channel ID (Copy ID).

tnx
