name

Optional name of the execution. For STANDARD workflows, this name must be unique for your Amazon Web Services account, region, and state machine. If a previous execution with the same name exists, you can reuse the name 90 days after it closes. For EXPRESS workflows, execution names can be reused immediately. For more information, see Limits Related to State Machine Executions in the Step Functions Developer Guide.

If you don't provide a name for the execution, Step Functions automatically generates a universally unique identifier (UUID) as the execution name.

A name must not contain:

• white space

• brackets < > { } [ ]

• wildcard characters ? *

• special characters " # % \ ^ | ~ $ & , ; : /`

• control characters (U+0000-001F, U+007F-009F, U+FFFE-FFFF)

• surrogates (U+D800-DFFF)

• invalid characters (U+10FFFF)

To enable logging with CloudWatch Logs, the name should only contain 0-9, A-Z, a-z, - and _.
