Invitations for Slack

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

Share of active installs on each version of this plugin · 100% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

   This plugin is great and it works as expected when you use Slack’s legacy token API: https://api.slack.com/custom-integrations/legacy-tokens Just a hint for other users who can’t get it to work. I was able to figure it out so I thought I’d pass on the link to the API this plugin uses. Thanks for a great plugin! It’s exactly what I need. 🙂

   Plugin doesn’t work unfortunately. Have raised several issues in the support forum and still no response after months. This topic was modified 9 years, 5 months ago by Anthony Hortin.

   While the author is not responsible for Slack itself, having at least basic instructions on how to obtain a proper Slack Token would result in a much higher rating. Currently it works with a Test token, but that’s not a proper setup.

   This plugin does exactly what it says and seems to work well. I had some issues with it’s CSS in widgets and a minor issue with default channels, but @rheinardkorf responded quickly and pushed updates to both issues in a short time. Thanks!
