Create Helper Flows

Follow the below steps to create a helper flow:

1. From the explorer menu, right-click Helper Flows and select Add Folder.
2. Provide a suitable name for the folder. These folders can be used to segregate and categorize the related helper flows together.
3. Right-click the created folder and select Add.
4. In the properties panel, configure the properties as required and then click save.

Property	Description	Comments
Name*	Provide the name of a helper flow.	Name must start with a character followed by alphanumeric or '_'. No spaces are allowed. Except underscore (_), no other special characters are allowed. Name cannot start with a number.

6. Click save icon to save a helper flow.

The "Helper Flow updated successfully" message displays upon successful update.
