The CoinPayments API documentation defines a standard, language-agnostic interface to the CoinPayments API. The platform allows merchants to integrate the payment system into their own websites or applications, enabling their customers to pay for goods or services with cryptocurrency.

You will find everything you need to authenticate requests, the parameters to include, response schemas, error handling, and implementation examples — a simple, secure way for merchants to accept cryptocurrency payments.
