Legacy trials in Zephr allow users limited access to features, such as free article views, on a fixed or rolling basis.

Zephr offers the ability to create legacy trials. A legacy trial gives an end user limited access to a feature, on a one-off or recurring basis. For example, you may offer users three free views of article content when they register. This would be managed as a legacy trial.

The Legacy Trials node can be used to create the following types of trial:

• Fixed trial Fixed Trials apply for a fixed period of time, such as ten views each calendar month.
• Rolling trial Rolling Trials apply to an ongoing period, such as ten views in the last 35 days from the start of the session.

We provide examples that take you through using the Legacy Trials decision node as follows:

• Create a Fixed Trial
