Question about Notification after subscription started with offer code?

Hello I want to know about App Store server notification type after subscription started with offer code,

question is

when someone starts a subscription with an offer code, only type OFFER_REDEEMED[subtype INITIAL_BUY] is send to server?

or

both type OFFER_REDEEMED[subtype INITIAL_BUY] and type SUBSCRIBED[subtype INITIAL_BUY] are send to server?

Replies

Just OFFER_REDEEMED

thanks

Only one v2 server notification should be sent per event.
