my organization was using Slack, and decided to move to Google Hangouts Chat. I used channels to coordinate with different teams. How do i migrate these users to Hangouts Chat rooms?
(Issue) Chat rooms allow duplicates, and are created private. So new users cannot see them & join. They end up creating copies of a similar common room each time.
Either of the following kinds of options are fine with me.
Export users list email-addresses from my Slack channel. Import these users into Chat as @email-id . I can't seem to get the email-list from Slack
Send Chat room shareable invite link to channel users. Google Chat rooms don't give shareable invite link.
As Erik said, the operation you are looking for is users.list. Though you need to ensure you have users:read and users:read.email set in your environment. This will also give you a bunch of empty entries though, as it will include all bots and apps on your workspace, which do not have emails.
I wrote a quick app using Transposit (disclaimer: I work for them) that you can fork here that will return an array of all valid emails in a Slack organization for you. Authenticate with Slack, and it should work by just running get_emails.js.
Unfortunately, we do not yet have a Hangouts connector, so we can't automate the whole process through this app, but I hope you find it helpful! Let me know if you have any questions in a DM, or message us at support@transposit.com.
