How can external UEFN developers access the URC Live Testing environment?

Hello,

I’m an independent UEFN developer researching Unreal Revision Control (URC) and its developer services.

I found these endpoints referenced in Epic Games’ testing instructions:

Production endpoint:
http://urc-uefn.live.ucs.on.epicgames.com

Testing endpoint:
http://urc-uefn.livetesting.ucs.on.epicgames.com/

The instructions specifically state that the livetesting endpoint should be used when testing.

I’d like to clarify a few things:

  1. Is the URC Live Testing environment accessible to independent UEFN developers?

  2. Does accessing it require an Epic organization, special permissions, or an internal VPN?

  3. Is there public API documentation available?

  4. Is there an official onboarding or access request process for external developers?

I contacted Epic Games Support, but they redirected me to the Developer Community forums for UEFN-related questions.

I’m looking for the official and authorized way to access this testing environment.

Thank you!
