Multi-language Discord webhook examples

All examples implement the same essentials:

POST JSON to the webhook URL
429 Retry-After backoff
5xx single retry
Webhook URL read from DISCORD_WEBHOOK env var

Run any of them after exporting the env var:

export DISCORD_WEBHOOK="https://discord.com/api/webhooks/<id>/<token>"

Language	Runtime needed	Sample
Python	3.10+, `pip install discord-alert-transport`	full package — severity routing + audit mirror + backoff
JavaScript (Node)	Node 18+, stdlib `fetch`	raw send + backoff
TypeScript	Node 18+, `tsx`	typed embed + backoff
Go	Go 1.21+, stdlib `net/http`	embed + 429/5xx retry
Rust	Rust + `reqwest` + `tokio` + `serde_json`	async send + backoff
Bash	bash + curl (+ optional jq)	works anywhere curl is installed
PHP	PHP 8+, stdlib `curl`	embed + backoff
Ruby	Ruby 3+, stdlib `net/http`	embed + backoff
Java	Java 11+, stdlib `java.net.http`	single-file, no Maven
C# (.NET)	.NET 6+, stdlib `HttpClient`	typed payload + backoff

Minimal viable example (any language)

The simplest possible send — no embed, no backoff, no error handling. Use this to verify wiring before going production.

curl

curl -X POST -H "Content-Type: application/json" \
  -d '{"content":"hello"}' "$DISCORD_WEBHOOK"

Python (one-liner, no package)

import urllib.request, json
urllib.request.urlopen(urllib.request.Request(
    URL, data=json.dumps({"content": "hello"}).encode(),
    headers={"Content-Type": "application/json"}, method="POST"))

Node.js

await fetch(URL, {method:'POST', headers:{'Content-Type':'application/json'}, body:JSON.stringify({content:'hello'})});

Go

http.Post(URL, "application/json", strings.NewReader(`{"content":"hello"}`))

Bash

echo '{"content":"hello"}' | curl -d @- -H "Content-Type: application/json" "$URL"

When to use the Python package vs raw HTTP

Need	Use
Just send a one-off	Any language, raw HTTP
Build a long-lived service	Either — port the package’s ~150 LOC or `pip install discord-alert-transport`
Severity-routed channels + audit mirror	Python package (or port `sender.py`)
Embed length limits enforced	Python `build_embed` helper
Secret-safe `__repr__` / logging	Python package
Async/threaded fan-out	Wrap any of these in your own queue

Don’t see your language?

The protocol is universal. Any HTTP client + JSON serializer works. PR welcome — add a sample under examples/<language>/.

Next: severity routing.
