Creation of bills

const projectId = "0000001"; // shop id
const apiId = "000000001"; // api id
const apiPassword = "api"; // api password
const notificationPassword = "notification"; // notification password

const inFiveDays = new Date().getTime() + 1000 * 60 * 60 * 24 * 5;
const qiwi = new QiwiShop(projectId, apiId, apiPassword, notificationPassword);

// this action is optional
qiwi.beforeCreateBill = function (billId, data) {
  // you can save some information to db before the request e.t.c.
  // you can return a promise
}

app.post('/payments/bill/create/', (req, res, next) => {    
  qiwi.createBill({
    user: 'tel:+7910100100',
    amount: '10',
    ccy: 'RUB', 
    comment: 'recharge',
    lifetime: new Date(inFiveDays).toISOString(),
    pay_source: 'qw',
    prv_name: 'example.com' 
  }).then((result) => {
    if(!result || !result.response || result.response.result_code != 0) {
        throw new Error('Qiwi bill creation fail');
    }
    
    // redirect to payment (optional)
    res.redirect(qiwi.getPaymentUrl({ 
      shop: qiwi.projectId, 
      transaction: result.response.bill.bill_id 
    }));
  });
});

Handling a notification

// notification handler 
const successHandler = (data, callback) => {
    // data === req.body    
    // save payment info or something else to db e.t.c    
    // callback() or return promise
};

const errorHandler = (err, meta) => {
    // you can save something to a file, db e.t.c.
    // the operation must be synchronous or in the background 
};

let authenticationBySignature = false; // false == basic authentication

app.post('payments/notification/', qiwi.notify(successHandler, errorHandler, authenticationBySignature));

Description

You can write a custom notification handler, but the library version includes a data/authentication validation and automatically send all headers in the necessary format
