Integrate a Payment Gateway Into a Website

2020, without exaggeration, revolutionized the digital world and stimulated the trends for eCommerce.

People flooded to buy goods online. To enable your business to make more money in 2020, you just need to integrate a payment gateway into a Drupal website.

What was once brought by caravans and sold by sailors — today you can buy or sell with one click and a payment gateway.

Today we offer a guide to the current topic of payment gateway integration into your Drupal website. To add a payment gateway into a website quickly, contact the Drupal web support company.

What is a payment gateway?

Figuratively speaking, payment gateways are like cash registers, such as in physical stores.

Payment gateways are special services that help make and guarantee secure money transfers.

Payment Gateway serves as an intermediary between you, the bank and your customer. It encrypts all information including:

  • card numbers
  • expiration date
  • CVV

so that no hackers can obtain and use this private information.

Payment Gateway Transaction Types

There are 5 types of Payment Gateway Transaction:

1. Authorization

During the authorization process, the bank checks whether the buyer makes a payment, that is, whether they have enough funds. Once that is confirmed, payment will be made.

2. Capture

At this stage, the actual transfer of funds from the buyer's account to the seller's bank balance is already taking place.

3. Sale

This type combines the first and second types of transactions. For example, this type of transaction occurs when you buy tickets online.

4. Refund

This is when the client refuses to purchase and the seller must use a refund payment and return the money.

5. Void

This transaction resembles a Refund but differs from it in that the refund occurs only if the funds have not yet been transferred to the Capture phase.

How the eCommerce payment gateway works and why you need it?

If you have an eCommerce site but haven't added a payment gateway to it yet, do it. You need this in order for all transfers and receipt of funds to be safe and fast.

What do payment gateways do?

  1. The customer has decided to purchase a certain product.
  2. The customer visits your website (which already has an eCommerce payment gateway).
  3. The customer enters all the necessary details of their card and clicks the buy button.
  4. The customer chooses a convenient payment method.
  5. The browser securely encrypts all data and via SSL forwards the request to the bank.
  6. The bank checks the correctness of the data and allows or rejects the request.
  7. If everything is correct, then a message is sent to the site via the payment gateway about the successful completion of the payment process.
  8. Funds transfer from the customer's account to the seller's account.
  9. The deal is successful and everyone is happy.
