Enables expansion of trial offer prices Public preview
What’s new
You can now expand the end_behavior.transition.price property of Trial Offers. Previously, this property returned the price object’s ID as a string. With this change, you can now retrieve the full Price object by including end_behavior.transition.price in the expand parameter when creating or retrieving trial offers. Read more about expanding responses.
Impact
You can access complete pricing information without making separate API calls to retrieve Price objects on trial offers. When you expand the price property, you get immediate access to pricing details such as the amount, currency, billing interval and other Price object properties directly within the trial offer response.
To use this feature, include end_behavior.transition.price in the expand parameter when working with trial offers.
