Listening to stripe Webhooks using functions

[shahar wider]

Hey,

I've been trying to listen to Stripe webhooks with firebase functions:

here is my code:

app.use(bodyParser.raw({ type: '*/*' }));

app.post('*', (req, res) => {

const sig = req.headers["stripe-signature"];

try {

const event = stripe.webhooks.constructEvent(req.body, sig, stripeWHEndpointSecret);

console.log(event);

}

catch (err) {

console.log(util.inspect(err));

res.status(400).end();

}

res.json({received: true});

});

export const stripeWebhooksListener = functions.https.onRequest(app);

 

and I keep getting this error:

Stripe official documentation on how to do it: https://stripe.com/docs/webhooks/signatures

// Set your secret key: remember to change this to your live secret key in production
// See your keys here: https://dashboard.stripe.com/account/apikeys
var stripe = require("stripe")("token");

// You can find your endpoint's secret in your webhook settings
const endpointSecret = 'secret';

// This example uses Express to receive webhooks
const app = require('express')();

// Retrieve the raw body as a buffer and match all content types
app.use(require('body-parser').raw({type: '*/*'}));

app.post('/webhook/example', (req, res) => {
  let sig = req.headers["stripe-signature"];

  try {
    let event = stripe.webhooks.constructEvent(req.body, sig, endpointSecret);
    // Do something with event
  }
  catch (err) {
    res.status(400).end()
  }

  // Return a response
  res.json({received: true});
});

app.listen(8000, () => console.log('Running on port 8000'));

Hello Shahar,

Did you check out our Functions example using Stripe? Seems like the best place to start.

Yeah, I've seen it... it has no reference to webhooks.
