Hi Community!

I thought I would share here how to create a Zap that can add reactions to messages filtered through keywords using Filter and Webhook actions.

 
The Zap can be more complex but for the example I made in 3 steps:

 

Summary View

Step 1: Trigger; I went ahead and used New Message Posted in Channel in Slack
Step 2: Action; Here I selected the Filter action with the option to “Only continue if...” 
Step 3: Action; Here I went with Webhook by Zapier; Custom Request in Webhooks by Zapier

 

Steps 1 and 2 are simple, so I will expand a bit more on Step 3 which for me was the trickiest part.

 

Step 3 Details  

App & event: 

  • App: Webhooks by Zapier
  • Event: Custom Request

Step Details: 

  • Method: POST
  • URL: https://slack.com/api/reactions.add
  • Data: channel=ChannelID&name=EmojiName&timestamp=MessageTs
  • Unflatten: False
  • Headers: 
    • Authorization: Bearer xoxb-your-personalized-slack-token
    • Content-type: application/x-www-form-urlencoded 

 

Action Details

 

Finally, here are a couple of links to resources that have helped me to get this Zap in action:

Hope this is helpful and if there is anything I can clarify on the above, please don’t hesitate to reach out.

 

All the best,
