FAQs
What is a Payment API?
A Payment API is a set of protocols, tools, and definitions that enable all parties involved in the payment flow to communicate. It serves as a bridge between merchants, customers, and financial institutions, facilitating secure and seamless transactions in various digital environments.
How do payment APIs work?
Payment APIs facilitate seamless payment processing by enabling applications to request and handle payments securely. When a transaction is initiated, the merchant's application sends necessary details to the payment API, which then interacts with the payment processor or financial institution to authorize and finalize the transaction. Subsequently, the API relays the transaction outcome back to the merchant application, confirming its success or failure.
What does a Payment API do?
A Payment API streamlines payment acceptance, processing, and management. It handles tasks such as transaction authorization, encryption, and fraud detection, ensuring payment data security. Additionally, it offers features for managing recurring payments, refunds, and reconciliation, empowering merchants with comprehensive control over payment operations. Ultimately, a Payment API enhances user experience and enables businesses to accept payments across different channels and devices securely.
