Discord Webhook

Use Discord Webhooks via direct curl calls to send messages to Discord channels without setting up a bot.

Official docs: https://discord.com/developers/docs/resources/webhook

When to Use

Use this skill when you need to:

• Send notifications to Discord channels
• Post alerts from CI/CD pipelines
• Share updates with rich embeds
• Upload files to channels
• Simple integrations without bot complexity

Prerequisites

1. In Discord, go to Server Settings → Integrations → Webhooks
2. Click "New Webhook"
3. Choose a name and target channel
4. Click "Copy Webhook URL"

export DISCORD_WEBHOOK_URL="https://discord.com/api/webhooks/1234567890/abcdefg..."

Security: Never expose webhook URLs publicly - they require no authentication.

How to Use
