This is definitely needed.
Could you please elaborate whether you are looking for login into slack with wild apricot credentials, or login into WA with slack (as it is already implemented for google+ and facebook)?
I'd love to see a Slack integration. I would like to see a separate slack channel for an event with all attendees automatically added to the channel.
Even though it is not a direct implementation, I hope this could be helpful:
We just launched integration with Integromat platform, which helps to build automated workflows. We also provide several templates for quick start, and one of them allows to copy google calendar events into WA events. So if you share a google calendar for events submission, then the scenario could copy submitted events into your Wild Apricot account.
You can try this integration by this link https://www.integromat.com/en/integration/2275-copy-google-calendar-into-wild-apricot-events
Any idea when this will be released? I am reviewing systems at the moment and this is a requirement.
