Getting Started

Circle Payments API

The Circle Payments API allows you to take payments from your end users via traditional methods such as debit & credit cards, bank accounts, etc., and receive settlement in USDC.

The Circle Payments API has been designed with any business or internet commerce in mind, not just crypto applications, and it's based on Circle's extensive experience processing millions of card payments since 2014.


With the Circle Payments API you can:

  • Take card payments for goods or services on your commerce app or website.
  • Build a credit & debit card on-ramp for your crypto exchange.
  • Take card deposits for your savings, lending, investing or P2P payments product.

All of that for customers across 150+ countries. Very soon, the Circle Payments API will also support other payments rails such as ACH and wire transfers, and not only for payments but also for payouts.

Getting Started

There are two basic ways to get started with the Circle Payments API.

1⃣ You can check our Payments Quickstart guide to get a sample web application up and running and process your first card payment that settles in USDC in a few minutes.
