Short answer is that it’s a gap that the Gift Cards team is aware of but hasn’t been prioritized yet.
There’s an existing thread requesting this (created, updated, expired, deactivated topics), and it’s come up internally from multiple partners as well - so it’s definitely on the radar! I’ve added your use case to the internal feature request, hopefully the continued interest prompts movement on this shortly.
For now the best you can do is use order webhooks as a trigger and query from there, which I know isn’t great for detecting updates, expirations, or deactivations.
