EPP Testing Services (OT&E)

EPP testing (OT&E), without trial and error.

We help registrars complete EPP OT&E with registries, verify flows, and move to production with clear, tested behaviour instead of guesswork.

Works with any registrar platform.

What we help you test

• Core flows for domain create, renew, transfer, restore, and contact management.
• Registry-specific test cases and requirements, including corner cases and error handling.
• Session handling, connection behaviour, and EPP polling flow that matches registry expectations.
• Result codes and responses that align with the registry’s OT&E acceptance criteria.
• Optional help integrating our EPP client or your existing registrar platform.

Good fit if: you are working on new accreditation, onboarding with a new registry, or want a safe environment to validate changes before you touch production.

Why use our EPP OT&E service?

We live in registrar and registry integrations every day. The goal is to make OT&E a controlled, repeatable exercise instead of a long debugging session.

Experience with real registries

We work with multiple registrars and registries across ccTLD and gTLD space. This means your OT&E runs follow patterns that have already passed in production.

Tools that speak EPP

We use our own EPP client for testing and guide you on how to adjust your registrar system for full compatibility, whether you use Namingo or another platform.

Focused on passing OT&E

We concentrate on what your target registry actually checks. The output is a clear set of actions that help you complete OT&E and move on to real registrations.

How the OT&E process works

Each registry has its own flavour of OT&E. The structure is similar, so we keep the process simple and predictable.

Step 1

Choose your TLD

You pick the target registry and TLD, share your current setup, and tell us whether you use Namingo, WHMCS, FOSSBilling, Loom, or an in-house platform.

Step 2

Initial testing

We perform the OT&E sequence using our EPP client to validate registry connectivity, commands, and responses.

Step 3

Integration

We guide you in configuring and tuning your own system, test account, and EPP commands, then verify that your platform passes the required OT&E flows.

Step 4

Completion and handover

After the registry confirms OT&E success, we provide a summary of results and reusable notes for audits or future registry integrations.

Details vary by registry and TLD. We agree the exact steps and boundaries before we start.

EPP OT&E testing packages

Fixed-price packages for popular TLDs. Each includes EPP test execution with our client, review of results, and step-by-step guidance to help your platform meet the registry’s OT&E requirements.
