-H "Content-Type: application/json" \
-d '{"content": "Deploy completed"}' \
-w "\nHTTP Status: %{http_code}\n"
Send a Rich Embed
curl -s -X POST "$DISCORD_WEBHOOK_URL" \

{"name": "Status", "value": "Success", "inline": true},
{"name": "Duration", "value": "2m 34s", "inline": true},
{"name": "Branch", "value": "main", "inline": true}
],

}]
}' -w "\nHTTP Status: %{http_code}\n"

- Rate limit: 5 requests per 2 seconds per webhook
- Max 10 embeds per message, 2000 chars per content field
- Returns 204 on success (no response body)
