How EPP works
EPP is a client-server protocol, where all communications use XML as defined by a series of schemas.
The normal conversation between a client and the server will be:
- Client connects to server over SSL using TLS 1.2
- Server identifies itself and the commands and extensions that it supports.
- Client logs in by supplying login name and password.
- Client polls the server to see if there are any notifications waiting to be collected and then collects them (or it could do this later).
- Client issues commands to server, which then replies immediately with response status.
- Client then idles until it has more commands to send, polling periodically for any notifications.
Benefits of using EPP
The main benefits of using EPP are:
- Responses to commands are generally instant. You can issue a command to register a domain, get a response and then confirm with your customer that this has happened all in real time.
- Your investment in EPP client programming should be transferable when integrating with the EPP service of other registries.
- You can choose when to collect notifications that we send you and can be sure that you have received them.
What you need to use EPP
You will either need to write your own EPP client or buy one off the shelf. Your software will then need to be able to connect directly to the EPP server using SSL.
For an explanation of the commands used for EPP please refer to the EPP commands document.
To connect to our EPP server you need to register for this service. We also provide an EPP testbed (Operational Test and Evaluation – OT&E) to allow you to test your EPP implementation.
Standard EPP is defined in RFC 5730, RFC 5731, RFC 5732 and RFC 5733.
From 4 September 2018 you will need to use TLS 1.2 or higher for your EPP connections.
