Hosted Payment Gateways

One of the major drawbacks is that sometimes the redirection may disrupt the checkout flow and impact the user experience.

Non-Hosted Payment Gateways

It is also known as Integrated Payment Gateways. Non-hosted payment gateways enable customers to complete transactions directly on the business website without being redirected to any external platform, no third party is involved in the transaction.

Businesses using Payment Gateway Integration Services must follow Payment Card Industry Data Security Standard (PCI DSS) compliance rules. It states that they should be responsible for storing, securing, and conducting each transaction. There is another option, where companies can opt for a white-label payment gateway as a non-hosted solution. These are prebuilt gateways that can be customized and branded. One of the white-label solutions designed for merchants is MasterCard.

API-Based Integration

Direct Post Integration

iFrame Integration

Similar to the direct post-integration method, here customers can make payments directly on the merchant website without being redirected to another platform. This integration embeds a payment form via iFrame supporting a wide range of payment options and providing a smooth checkout experience.

Two examples are Payza and Worldpay.

Mobile SDK Integration

Mobile SDK Integration lets businesses integrate a payment gateway directly into the mobile app to provide an optimized and seamless payment experience. PayPal Mobile SDK and Stripe Mobile SDK are two examples that facilitate secure and convenient in-app payments. If you have a mobile-first business, this is a great option with the least redirection and seamless checkout. However, it does come with challenges, such as the need for specialized app development skills and continuous maintenance to ensure it is compatible with the new updates. Despite its complexity, it’s a powerful solution for businesses that want to reach mobile-savvy customers.

Subscription/Recurring Payment Integration

The subscription or recurring payment integration is intended to handle reoccurring payments, especially those belonging to subscription-based businesses. Some examples include Stripe Subscriptions and Recurly. This solution automates billing and invoicing and reduces manual effort. However, it’s just for businesses that use subscription models.

Cryptocurrency payment gateways enable merchants to accept payment in cryptocurrencies such as Bitcoin and Ethereum. Such examples are Coinbase Commerce and BitPay. Attracting tech-savvy and global customers and reducing transaction fees through these gateways. However, they encounter challenges such as fluctuating currency values and limited widespread adoption.
