You must follow specific limits when using CloudFlow. This topic describes the naming-related limits and account-related limits that apply when using CloudFlow.
Naming-related limits
You can name flows and executions based on the following rules:
The name can contain letters, digits, underscores (_), and hyphens (-).
The name must start with a letter or an underscore (_).
The name is case-sensitive.
The name must be 1 to 128 characters in length.
