# ResolveAlias


 **This API works with the following fleet types:** EC2, Anywhere, Container

Attempts to retrieve a fleet ID that is associated with an alias. Specify a unique alias identifier.

If the alias has a `SIMPLE` routing strategy, Amazon GameLift Servers returns a fleet ID. If the alias has a `TERMINAL` routing strategy, the result is a `TerminalRoutingStrategyException`.
