I am setting up in-app purchases for my mobile application and the setup is completed successfully. I have three subscription plans: Monthly, Quarterly, and Annually. I want to introduce a free trial for users who subscribe to any of these plans for the first time.

If I set up a 2-month free trial for all plans, will I receive a webhook notification from iOS/Android at the start of the free trial and at the end of the free trial (two times), or will I only receive a webhook notification after the completion of the 2-month trial when the user’s account is charged and the paid subscription begins?
