What changed
Still works today. This is the earliest warning you will get before it is removed.
Affects POST /v2/customers/{customer_id}/cards. Nothing breaks today, which is exactly why this is worth acting on now rather than when it starts returning 404.
Who is affected
Code that calls POST /v2/customers/{customer_id}/cards.
