how to send a message to discord channel using the webhook via shell script

discord-bot.sh

#!/bin/bash

##
# Discord Webhook
# Change the 'your_discord_webhook_name' with your actual Discord Webhook
##

##
# add to linux cron:
# sudo crontab -e
# https://crontab.guru/
##

discord_url="your_discord_webhook_name"

generate_post_data() {
  cat <<EOF
{
  "content": "Hello! World!",
  "embeds": [{
    "title": "Embeded Title",
    "description": "Description",
    "color": "45973"
  }]
}
EOF
}


# POST request to Discord Webhook
curl -H "Content-Type: application/json" -X POST -d "$(generate_post_data)" $discord_url

Thank you, OP. I drew inspiration and adopted a generalized approach:

#!/bin/bash

# Generalized Discord Notification Script

discord_url="your_discord_webhook_url"

# Define a function to send a message
send_discord_notification() {
  local message=$1
  
  # Construct payload
  local payload=$(cat <<EOF
{
  "content": "$message"
}
EOF
)

  # Send POST request to Discord Webhook
  curl -H "Content-Type: application/json" -X POST -d "$payload" $discord_url
}

# Use the function
send_discord_notification "Hello, World!"
