Trying to see if there is a way to find if a user has been active on a queue during a specific historic time range.
I've tried both the /api/v2/analytics/users/details/query and /api/v2/analytics/queues/observations/query but cant seem to find what I'm looking for. Anyone done this before and can give me a hand?
There is no queue (or skill) assignment history. It's "now" only.
The only way to know if someone was on a queue was for them to have recorded some activity on that queue during the period, which isn't ideal for many reasons you'd be asking the question.
If you're talking about activated/deactivated on a queue as opposed to just being a member of a queue then yes - the Audit API can likely give you what you're after.
