Payment experience FAQs
-
What is a payments API?
A payment API (Application Programming Interface) allows businesses and developers to integrate payment processing capabilities into their applications, websites or platforms. It provides a standardized way for applications to interact with payment gateways, enabling merchant account transactions such as accepting payments, issuing refunds and handling subscriptions.
-
How do payments APIs work?
Payment APIs work by facilitating communication between your application and the payment provider. When a customer submits payment information, the payments API securely transmits this data to the payment processor, which then verifies the details, processes the transaction, and returns a response indicating success or failure. Payment APIs often support popular payment methods such as debit cards and credit cards, ACH bank transfers and digital wallets like Apple Pay® and Google Pay®. Additionally, there are alternative payment methods (APMs) that are popular in specific regions of the world. For example, UK consumers may be more familiar with PayPal® and Klarna, whereas Asia Pacific customers favor options such as Alipay, WeChat Pay and GrabPay for online payments.

What are the different types of Global Payments APIs?
- Transaction APIs: These APIs handle standard payment transactions, including authorizing and capturing funds, processing refunds, and voiding payments.
- Subscription APIs: Designed for recurring payments, subscription APIs allow businesses to manage billing cycles, provide multiple payment options as well as supporting customer subscriptions and automated card payments.
- Tokenization APIs: Tokenization APIs enhance security by replacing sensitive card details with a unique token, reducing the risk of fraud while allowing seamless future transactions.
- Payout APIs: Payout APIs enable businesses to send payments to external parties, such as vendors or employees, directly from their merchant account.
- Preauthorization APIs: These APIs allow businesses to make a payment request, which will then hold a specific amount on a customer’s payment method without capturing the funds from the cardholder’s bank account. Preauthorization APIs are typically used for scenarios like hotel bookings or car rentals.
