How to add a check reaction in Slack and verify its existence

I wondered if it would be possible to let the zap add a `:check:` reaction as a latch, and then check for the existence of that reaction.

Hi ​@Ambreen Younas, welcome to the Zapier Community 👋

 

You might be able to work with Slack's “Get Message Reactions” search action, which returns a message and its list of reactions. This could be a great way to verify if specific reactions exist on messages.

 

This approach would allow you to:
• Verify whether a particular reaction exists on a message

• Build conditional logic based on reaction presence using Filter by Zapier or Paths by Zapier

 

 

You can take a look at all of the existing Slack Triggers and Actions here:

I hope this helps!

Hi ​@Ambreen Younas 

Try these Slack Zap events…

 

Trigger: Slack - New Reaction Added

AND

Action: Slack - Add Reaction
