4 Different Types of Payment Gateway Integration:

Consider your business's demands and infrastructure when choosing the appropriate payment gateway for your website or app.

The key distinction between the 4 types of payment gateways is how they are integrated into your website. Some may need ongoing maintenance and technical support, but others may assist the host immediately.

The 4 different types of payment gateway are:

Local bank integration Payment Gateway
API-hosted Payment Gateway
Self-hosted Payment Gateway
Hosted Payment Gateway

1. Local bank integration Payment Gateway:

This type of payment gateway links directly to the bank's payment system. This is especially important for businesses that want to reach clients in a certain region or nation where the local bank is a well-known and trusted company. The efficiency of local bank integration is heavily dependent on a bank's technology and the degree of assistance it can offer for online transactions.

Cost: - High cost due to multiple APIs.

2. API-hosted Payment Gateway:

These provide a straightforward checkout procedure immediately on the company's website or app. Payment information is acquired using an application programming interface (API). This approach offers a seamless and integrated user experience, but it requires a secure cardholder data environment to fulfill data protection rules.

Cost: - Generally, there are no setup or integration charges, and commissions are reduced.

3. Self-hosted Payment Gateway:

Transaction data is gathered on the business's website via these gateways. Businesses have complete control over the checkout and consumer experience. Businesses that host this sort of gateway must also handle payment data securely and follow data security regulations such as the Payment Card Industry Data Security Standard (PCI DSS). Businesses that pick this option often desire a completely personalized payment experience and can handle the associated security requirements.

Cost: - High investment for setup, maintenance, and customization.

4. Hosted Payment Gateway:

These are offered by third-party providers. When a consumer makes a payment, they are led to the payment service provider's platform, where they enter their payment information and finish the transaction. Customers are directed back to the business's website once their payment has been completed. These gateways are often simple to integrate and provide high security because the data is handled on the provider's servers. Businesses have less control over the consumer experience because the payment procedure takes place off-site.

Cost: - Low startup costs, continuous commissions, and an economical start.

Comprehensive testing, including unit, integration, and end-to-end tests, to ensure the gateway functions properly within the system.
