Checkout Getting Started

With myPOS Web Checkout, you can easily integrate a secure payment gateway into your website or web app and start accepting online payments from all major credit and debit cards.

Tip: Always test your integration before going live.

myPOS Web Checkout is a hosted payment gateway, which eliminates complicated PCI requirements and lets you focus on your business.

Integrating myPOS Checkout into your online business allows you to instantly receive payments, track and manage all financial transactions, and change your Checkout settings. You can also tokenize and store cards for later purchases, without storing sensitive cardholder data on your side.

  • PHP
  • Java

The SDKs include integration and configuration information, as well as code samples.

If you use another language, check our API reference for details.

myPOS Web Checkout Provides

  • Secured page and communication channel with the merchant
  • Storage of merchant private data (shopping cart, amount, payment method, transaction details, etc.)
  • Financial transactions to VISA, MasterCard, JCB, Bancontact
  • Operations for the front-end: purchase transactions, manage Checkout settings
  • 3D Secure processing for direct payments with debit or credit cards

The API provides access to the Payment Gateway managed by myPOS Europe Ltd. By using secure hosted checkout pages, merchants comply with security rules for handling customer data. Data is stored on secure servers and is not exposed to compromise.

Customer Payment Flow

When using myPOS Web Checkout, your customers are temporarily redirected to a secure hosted payment page. The payment gateway guides the customer through the payment process, checks sensitive cardholder data, and processes the payment through card schemes (VISA, MasterCard, American Express, JCB, UnionPay, Bancontact). If the card is enrolled for 3D Secure, the customer is redirected to their bank’s website for authentication, then returned to your site.

Another payment method is iDeal, mainly for merchants in the Netherlands but available to everyone. The gateway connects to the client’s bank and requests funds from the specified account.

Once the payment is complete, the customer is returned to your website. You will receive a notification with the payment and transaction details.
