# Registrant API integration specification REPP uses HTTP/1.1 protocol (http://tools.ietf.org/html/rfc2616) and Basic Authentication (http://tools.ietf.org/html/rfc2617#section-2) using Secure Transport (https://tools.ietf.org/html/rfc5246) with certificate and key (https://tools.ietf.org/html/rfc5280). Credentials and certificate are issued by EIS (in an exchange for desired API username, CSR and IP). To quickly test the API, use curl: curl -q -k --cert user.crt.pem --key user.key.pem https://TBA/repp/v1/accounts/balance -u username:password Test API endpoint: https://testepp.internet.ee/repp/v1 Production API endpoint: TBA Main communication specification through Restful EPP (REPP): [Authentication](registrant-api/v1/authentication.md) [Domain related functions](registrant-api/v1/domain.md) [Contact related functions](registrant-api/v1/contact.md)
