| Field | Description |
| --- | --- |
| **API Name** | The requirement for uniqueness applies only to elements within the current flow. Two elements can have the same API name, provided they're used in different flows. An API name can include underscores and alphanumeric characters without spaces. It must begin with a letter and can’t end with an underscore. It also can’t have two consecutive underscores. |
| **Description** | Helps you differentiate the constant from other resources. |
| **Data Type** | Determines the type of value that the constant can store. You can’t change the data type of a previously saved constant. |
| **Value** | The constant’s value. This value doesn’t change throughout the flow. |
