6. Click Save.

   

Add the Clear order Data (Subflow) node

Use the following steps to add the Clear order Data (Subflow) node to the synchronous flow:

1. Drag a subflow node into the flow to the right of the new Check if session has orderId (Decision) node created in the previous step. The node will be connected later in this section

2. In the New Sublow screen, select "Clear Order Data" from the "Referenced Flow" drop down. Use these values.

3. Use these values for the next set of fields

   • Label: Clear order Data

6. Click Save.

Connect the Check if Session has orderId (Decision) node

Use the following steps to connect the Check if Session has orderId (Decision) node to the synchronous flow:

1. Delete the connector between "Update session" (Update Records) and "Cart to Order" (Action) nodes.

2. Connect the following nodes:

   • Update session (Update Records) node to Check if session has orderId (Decision) node.

   • Check if session has orderId (Decision) node to Clear order Data (Subflow) node.

     • Choose the "Order exists" Outcome when prompted.

   • Check if session has orderId (Decision) node to Cart to Order (Action) node.

     • This should default to the "Default Outcome."

   • Clear order Data (Subflow) node to Cart to Order (Action) node.

   

Note: Additional screen nodes shown in the screenshot will be added later in this topic.
