I created a javascript variable to generate a random number and assigned to a custom HTML tag to push the value to the data layer.
Value pushed to a variable called OrdId
Data layer variable created to pull the value from data layer:
Data layer variable (OrdId) added to the Order ID parameter on floodlight tag setup.
TestingĀ – GTM debug
Push to data layer:
Tags firing with the OrdId unique value for all.
