Slack Message Sender

This automation will connect to the website on your behalf. The safest and most efficient way for Phantombuster to authenticate as yourself is by using your session cookies. To make that process as easy as possible you can use PhantomBuster's browser extension. It's a 2-click installation.

Get it for Chrome

Get it for Firefox

If you're operating from another browser and/or want to do it manually, here is how to do it.

The second argument is Slack Workspace URL. We need it to know which Slack users you want to target.
This URL should look something like yourcompany.slack.com.

Input the spreadsheet URL containing your recipient's IDs. Create a spreadsheet on Google Spreadsheet. Gather the Slack user's IDs of the people you want to message in that spreadsheet. This automation can help you scrape Slack Users. One URL per row, all in column A.

Make this spreadsheet public so Phantombuster can access it.

Paste the spreadsheet's URL to Phantombuster.

Automation always produces better results in the long run. Set the Phantom to launch repeatedly and get results while you're away!

This Phantom runs from the cloud, which means you don't even need to have your browser open or computer on for these launches to happen.
