API Basics

Last update: 2020-06-04 | Edit on GitHub

P2P Invoices API opens a way to operations with invoices from your service or application. Invoice is the unique request for the payment. The user may pay the invoice with any accessible means. API supports issuing and cancelling invoices, making refunds and checking operation status.

To use API, you need public and secret keys. Keys are available after registration on p2p.qiwi.com.

Invoicing Operations Flow

• User submits an order on the merchant’s website.

• Merchant redirects the user to Payment Form link. It automatically issues an invoice for the order. Or you may issue an invoice by API and redirects to the Payment Form.

• The user chooses the most convenient way to pay for the invoice on the Payment Form. By default, the optimal payment method is showed first.

• The merchant's service receives notification once the invoice is successfully paid by the user. You need to configure notifications on your Personal Page. Notifications contain authorization parameters which merchant needs to verify on its server.

• If needed, via the API merchant can:
  • request current status of the invoice,
  • cancel invoice (if the user has not initiated payment yet).
• When the invoice payment is confirmed, merchant delivers ordered services/goods.

Authorization

const QiwiBillPaymentsAPI = require('bill-payments-node-js-sdk');

const SECRET_KEY = 'eyJ2ZXJzaW9uIjoicmVzdF92MyIsImRhdGEiOnsibWVyY2hhbnRfaWQiOjUyNjgxMiwiYXBpX3VzZXJfaWQiOjcxNjI2MTk3LCJzZWNyZXQiOiJmZjBiZmJiM2UxYzc0MjY3YjIyZDIzOGYzMDBkNDhlYjhiNTnONPININONPN090MTg5Z**********************';

API requests are authorized by the API secret key (SECRET_KEY). Put this parameter to Authorization header as "Bearer SECRET_KEY".

Public key (PUBLIC_KEY) is used when issuing invoices via the Payment Form.

Keys are available after registration on p2p.qiwi.com.

Invoice Issue on Payment Form

It is the simplest way of integration. On opening Payment Form, client receives an invoice at the same time. The invoice data sends in URL explicitly. Client gets a Payment Form web page with multiple payment means. When using this method, one cannot be sure that all invoices are issued by the merchant. API invoice creation mitigates this risk.

Authorization on Merchant's Server

Upon receiving inbound notification you need to verify it by digital signature from notification HTTP header X-Api-Signature-SHA256. Signature is verified with HMAC algorithm integrity check with SHA256-hash function.

Signature verification algorithm is as follows:

1. Prepare a string of the following notification's parameters separated by |:

   invoice_parameters = {amount.currency}|{amount.value}|{billId}|{siteId}|{status.value}

   where {*} is the value of the parameter. All values should be treated as strings.

2. Apply HMAC-SHA256 function:

   hash = HMAС(SHA256, invoice_parameters, secret_key)

   where:

   • secret_key – function key;
   • invoice_parameters – string from step 1.

3. Compare X-Api-Signature-SHA256 header's value with the result of step 2.
