      operationId: CreateStateMachineAlias
      description: <p>Creates an <a href="https://docs.aws.amazon.com/step-functions/latest/dg/concepts-state-machine-alias.html">alias</a> for a state machine that points to one or two <a href="https://docs.aws.amazon.com/step-functions/latest/dg/concepts-state-machine-version.html">versions</a> of the same state machine. You can set your application to call <a>StartExecution</a> with an alias and update the version the alias uses without changing the client's code.</p> <p>You can also map an alias to split <a>StartExecution</a> requests between two versions of a state machine. To do this, add a second <code>RoutingConfig</code> object in the <code>routingConfiguration</code> parameter. You must also specify the percentage of execution run requests each version should receive in both <code>RoutingConfig</code> objects. Step Functions randomly chooses which version runs a given execution based on the percentage you specify.</p> <p>To create an alias that points to a single version, specify a single <code>RoutingConfig</code> object with a <code>weight</code> set to 100.</p> <p>You can create up to 100 aliases for each state machine. You must delete unused aliases using the <a>DeleteStateMachineAlias</a> API action.</p> <p> <code>CreateStateMachineAlias</code> is an idempotent API. Step Functions bases the idempotency check on the <code>stateMachineArn</code>, <code>description</code>, <code>name</code>, and <code>routingConfiguration</code> parameters. Requests that contain the same values for these parameters return a successful idempotent response without creating a duplicate resource.</p> <p> <b>Related operations:</b> </p> <ul> <li> <p> <a>DescribeStateMachineAlias</a> </p> </li> <li> <p> <a>ListStateMachineAliases</a> </p> </li> <li> <p> <a>UpdateStateMachineAlias</a> </p> </li> <li> <p> <a>DeleteStateMachineAlias</a> </p> </li> </ul>
