Trying to update to 3.0.x, if there are any issues with the ZoomAPI, you get fatal guzzle exceptions (like 400/401).
I think it would make sense to catch and log the exceptions, and then maybe trigger_error() or drupal set message a warning message as well. Might need to be in apitools instead of this module, haven't looked at where to add this yet.
Closed: cannot reproduce
3.0
