Use case for ExternalMatchmakerEventEndpoint

What exactly is the use-case for

the ExternalMatchmakerEventEndpoint in Matchmaker.StartGame?

https://api.playfab.com/documentation/matchmaker/method/StartGame

I'm currently getting InvalidParams with my StartGame call because I left this field blank. I'm currently thinking of passing in "" just so I pass something. But it makes me feel uncertain so I thought I'd ask.

It's for developers who are using external matchmakers, so that their matchmaker server can get the info on sessions that close (specifically, the event is "game_ended"). If you're not using one, feel free to pass in null.

Okay, that is what I thought. Thanks!

Maybe in the future, it could be changed to a non-Required parameter?

Yes, I'm opening a work item on that, as it does feel like a reasonable change.

null did not work, "http://www" did. If it's not really a required parameter an update to the API would be great. Or returned error messages that detail which parameters are still invalid. Incase a developer uses the forum to find answers and uses values provided by the PlayFab team.

Can you clarify your question? The ExternalMatchmakerEventEndpoint parameter is a required parameter in the Matchmaker API: https://api.playfab.com/documentation/Matchmaker/method/StartGame.
