Dynamic Items: What Is The Fallback Value And How Do You Use It?

When setting up a dynamic item, you’ll have the opportunity to add a fallback value:

This value will show whenever the conditions for the target fill value aren’t met. In the example above, if the testparam query parameter wasn’t present, or dididn’t have a value set, the word “fallback” would get sent to Custom 1.

When setting a dynamic item to target a text block, the text in the editor will act as a fallback if no fallback is set in the dynamic item.

If you have multiple dynamic items set up using the same target, you only need to set a fallback value for the last dynamic item in the list targeting that value.

In the example above, all five dynamic items are targeting the [DEMO] merge tag. 5166 is the only dynamic item in the list that has a fallback value. Dynamic items will execute in order, and once a dynamic item fills the target, no further attempts to fill that target will be made. So, if 5165 had a fallback value set, the user would see that value instead of test5 if the testparam URL param were set to “test5”.
