@cmelo As a reminder, we should document the new endpoint on mw.org. I've updated the AC to reflect that.

Not moving the task to QA as this is still to do.

New endpoint documentation added.
Remove Participants endpoint

I added an error that wasn't listed, LGTM now.

✅ removing one participant

✅ removing multiple participants

✅ removing all participants

✅ removing participants with API

One question for you @cmelo per this AC:

If the participant is removed, it is a soft delete in the system

Where can I find a record of the user being soft deleted? The removed users are not listed in the List Participants of a registration endpoint json that is returned. There is also no record of the deleted event in the List all registrations a participant has registered for endpoint json that is returned either. When users are removed is it actually currently a hard delete from the DB?

In the gif below I deleted all of the users of the event (I meant to just delete one user, but made a typo and accidentally deleted all of them) -- but after deleting them I can find no soft delete record of any of them related to the event. Is the soft delete AC still applicable?

Long story short, nowhere. The deletion is indeed soft, but the interface doesn't allow you to view deleted entries or restore them (although this may be implemented in later versions). If you do want to verify that the DB entries are still there, you'll have to manually query the DB, e.g., select * from ce_participants where cep_event_id=123.

Okay thank you @Daimona I was able to find all of the soft deleted users in the DB using that query. Moving this to product sign off as all AC is met.
