saweria-webhook-express is a simple Express middleware to verify Saweria webhook request using your stream key.

This middleware will checks whether the received request is a valid request from Saweria or not, it will:

• returns 403 if Saweria-Callback-Signature header isn't provided
• returns 401 if Saweria-Callback-Signature value isn't valid

Install

npm i saweria-webhook-express

Usage

const express = require("express");
const { createMiddleware } = require("saweria-webhook-express");

const app = express();

const verifySignature = createMiddleware("your-stream-key");

app.use(express.json()); // required since the middleware also reads the donation payload

app.post("/webhook", verifySignature, (req, res) => {
	console.log("New verified request from Saweria!");
	console.log(req.body); // donation payload
	res.sendStatus(200);
});

app.listen(8080);

createMiddleware also accepts 2nd parameter as options:

const verifySignature = createMiddleware("your-stream-key", {
	camelCase: true, // false by default
});

This will convert the body payload (req.body) from snake_case:

{
	version: "2021.07",
	created_at: "2021-01-01T12:00:00+00:00",
	id: "00000000-0000-0000-0000-000000000000",
	type: "donation",
	amount_raw: 69420,
	cut: 3471,
	donator_name: "Someguy",
	donator_email: "[email protected]",
	message: "THIS IS A FAKE MESSAGE! HAVE A GOOD ONE",
}

to camelCase:

{
	version: "2021.07",
	createdAt: "2021-01-01T12:00:00+00:00",
	id: "00000000-0000-0000-0000-000000000000",
	type: "donation",
	amountRaw: 69420,
	cut: 3471,
	donatorName: "Someguy",
	donatorEmail: "[email protected]",
	message: "THIS IS A FAKE MESSAGE! HAVE A GOOD ONE",
}
