Basic Concepts¶

How Do Payments Work¶

1. A customer on your website decides to checkout.
2. Your website creates a payment invoice by calling the Payelata.com API with the amount, a payment description, a Callbacks URL, and a URL we should redirect the customer to after that. In response, the API sends a list of available payment methods.
3. The client chooses the service and currency and pays for the order. Payelata.com takes over the transaction. In case the selected service is unavailable due to technical reasons or the client has entered incorrect data, Checkout page allows making a second payment attempt.
4. During payment processing, Payelata.com automatically sends Callbacks to check the payment status.
5. You get Callbacks with statuses via API to the dashboard and the specified Callbacks URL.
6. Having received the final status, you can display the client a page with payment status and thanks for the order. Payment comes to your selected currency account.

To create a payment invoice, you can use as both the dashboard and direct integration with API. And for interaction with your customers, use our ready-made Checkout page or develop your own hosted payment page. In any case, Payelata.com ensures the security of the client’s data processing and determine the best option for carrying out the transaction.

What is a Payment Gateway¶

The primary function of a payment gateway is to validate your customer’s payment details securely, make sure the funds are available for the payment and get you paid.

A payment gateway is a service responsible for processing and routing payments. It is the equivalent of a physical point of sale terminal that lets your customer submit their payment details. It securely passes sensitive financial information from the customer to the merchant and then between the merchant and the payment provider. The payment gateway tells you whether payment provider processing approves the charge, and submits it. The payment amount is deducted from your customer’s payment account and deposited into your merchant account.

Payment System and Payment Providers, Methods, Services¶

The payment system is a set of procedures and rules, and the technical infrastructure to support them. All this commonly makes it possible to transfer money without cash from one entity to another.

Payment providers (PSP) provides services within the payment system. As services, they can offer the organization of payment reception, Internet acquiring, agency cooperation scheme, act as international or local companies, have different conditions for opening accounts.

Payment method is a method of funds transferring. PSP operate a variety of payment methods, enable to receive payments through bank cards, bank transfers, mobile payments, and electronic wallets.

In addition to various payment methods, payment providers support different currencies (national, electronic, cryptocurrency). To facilitate integration with providers and subsequent routing of payments, Payelata.com uses the term of payment service that is a combination of payment method and currency. For example, payment for services in euros using the VISA QIWI wallet is handled with the qiwi_eur service.

Services include the properties and parameters properties and parameters required to initiate a payment, such as a customer’s wallet number, a card number, an authorisation data of their account. It is like a contract for the gateway protocol: the gateway can always expect the parameters listed in the service properties.

Payment and Payment Invoice¶

In terms of the Payelata.com system, a payment is a transaction responsible for transferring money from the client to the merchant account. Payment uses a specific payment service to transfer funds.

Unlike payment, a payment invoice is created without a specific payment service and can be paid by any of the methods available to the client.
