# Payments

Our API allows developers to execute Payments functions via HTTPS client using TLS 1.2 protocol. The Payment API is a Web API that accepts JSON payloads and returns JSON-encoded responses and needs API key authentication. A payment response includes the status of the request. It also includes processor-specific information when the request is successful and errors if unsuccessful
