APIs

Poplapay's "API first" philosophy means that our partners should be able to access all our data and functionality through APIs. These include POS APIs (local network and cloud), eCommerce APIs, and server APIs (transaction data and terminal/merchant management).

JSONPOS API

Protocol for connecting to the payment terminal, either directly via TCP or Bluetooth, or through the cloud. Used for purchases, refunds, printing and other operations performed directly on the payment terminal.

JSON-RPC Transport

Simple stream transport for JSON-RPC when connecting directly to the payment terminal without using WebSocket. Defines common conventions for all JSON-RPC connections.
