The payment id is invalid - Node Package

Ok, made some headway now on the server side. However I’m getting the following error: { type: ‘request’, message: ‘The payment id is invalid’ }

I’ve constructed the following setup using the examples:

const express = require('express');
const Mollie = require('mollie-api-node');

const router = express.Router();
const mollie = new Mollie.API.Client();
mollie.setApiKey('test_mytestAPIkey');

router.post('/webhook/:id', (req, res) => {
  const id = req.params.id;
  console.log('webhook triggered', id);

  mollie.payments.get(id, (payment) => {
    console.log('payment', payment);
    if (payment.error) {
      console.error(payment.error);
      return res.end();
    }

    if (payment.isPaid()) {
      console.log('paid');
    } else if (!payment.isOpen()) {
      console.log('abort');
    }
    return res.end();
  });
  return res.end();
});

router.get('/', (req, res) => {
  const Id = new Date().getTime();

  mollie.payments.create({
    amount: 10.00,
    description: 'My first API payment',
    redirectUrl: 'http://'.concat(req.headers.host).concat('/mollie'),
    webhookUrl: 'http://'.concat(req.headers.host).concat('/api/mollie/webhook/').concat(Id),
    metadata: { orderId: Id },
  }, (() => {
    return (payment) => {
      if (payment.error) {
        console.error(payment.error);
        return res.end();
      }
      console.log('http://'.concat(req.headers.host).concat('/api/mollie/webhook/').concat(Id));

      res.writeHead(302, {
        Location: payment.getPaymentUrl(),
      });
      return res.end();
    };
  })(this));
});

module.exports = router;

When I log the read the results in my terminal window after a GET request on mysite.nl/api/mollie, it seems that both the sent ID and the received ID are the same:

http://mysite.nl/api/mollie/webhook/1509674934006
GET /api/mollie 302 80.284 ms - -
webhook triggered 1509674934006
POST /api/mollie/webhook/1509674934006 200 48.966 ms - -
payment { error: { type: 'request', message: 'The payment id is invalid' } }
{ type: 'request', message: 'The payment id is invalid' }

Nonetheless, I’m getting that error. Is this normal to get this error in testmode, or am I doing something wrong?

I see you are using the old package using callbacks. Just a heads up: there is a npm install mollie-api-node@next package available written in ES6 that allows you to use promises.

Ah wait, there’s difference between my ID for my own administration and the ID you send back, right? I just did a console.log(req.body) and I got a randomized string. This must be the right thing.
