PayApp (페이앱) on a Mac

PayApp small-merchant payment links · E-Commerce

PayApp is a small-merchant and SNS-seller payment service that sends payment requests by SMS or URL. After seller sign-up, the integration values 연동 KEY (linkkey) and 연동 VALUE (linkval) appear in the seller admin under 설정 > 연동 정보. linkkey authenticates API calls; linkval is used to verify payment-result callbacks (feedbackurl). Every command goes through one endpoint selected by the 'cmd' parameter, and responses are URL-encoded key=value strings, not JSON.
