Ouch.

I assumed that, but you're probably right in that GET also works.
I had looked at the docs for the users.list method which would seem
the closest to what I need on the Slack side:

https://api.slack.com/methods/users.list

However, it's not as simple as a single API call and be done with it.
You'd have to script it a bit:

Which is not difficult, but not suitable for the Sympa "single URL
request" option.
