|---|---|
| ## `high_lifetime_value_adjustment` Union field. Conversion value adjustment to be applied to customers in the corresponding lifecycle and identified as high lifetime value. For example, for customer retention goals, high lifetime value adjustment is the incremental conversion value for lapsed customers who are of high lifetime value. High lifetime value should be greater than value, if set. `high_lifetime_value_adjustment` can be only one of the following: ||
| ### `additional_high_lifetime_value` | `double` Incremental high lifetime conversion value. |
| ### `high_lifetime_value_multiplier` | `double` High lifetime conversion value multiplier. |
| ## `value_adjustment` Union field. Conversion value adjustment to be applied to (non high lifetime value) customers in the corresponding lifecycle. For example, for retention goals, conversion value adjustment is the incremental conversion value for lapsed customers who are not of high lifetime value. `value_adjustment` can be only one of the following: ||
| ### `additional_value` | `double` Incremental conversion value. |
| ### `value_multiplier` | `double` Conversion value multiplier. |
