Stablecoin Payments Glossary
Payment API
A payment API is a software interface that allows an application to programmatically request, initiate, query, or manage payment functions.
Explanation
Stablecoin payment APIs can create payment requests, obtain deposit addresses, quote conversion amounts, check transaction status, initiate payouts, retrieve balances, and automate reconciliation. APIs allow payment functions to be embedded in merchant systems and other applications without requiring users to interact directly with the underlying blockchain or banking infrastructure.
Why it matters
APIs support automated and embedded payment services by standardizing how applications communicate with payment infrastructure.
Example
An e-commerce platform can call a payment API to create a USDC invoice and later query whether the required amount has been received.
