How do I create a zap which starts when a slack message created by another zap gets a reaction from a person message in that zap?

Hello all,

I want to create a zap that starts only when the slack message created by a previous zap (mentioning a specific person) gets a reaction from that specific person.

My already produced zap leads to a message on slack (mentioning two slack accounts) on a specific channel.

I want my other zap to get triggered when that message gets a specific reaction from the second slack account mentioned in that slack message: but I have not managed this.

Does someone know how to do this ?

Hi @vlsepd 

Try adding a Filter as Step 2:

Hi @Troy Tessalone thank your the quick reply.

That does work, until I try to actually set up the filter: I can’t find how to filter based on who initiated the reaction to the message. Do you know how to do that (potentially manually?)

Did you try using this setting in the Slack Zap trigger?


Hi, yes I have, of course,

But the specified user depends on something else which I can’t bring up in the trigger or later as a filter as I can’t find a way to filter based on who reacted with the slack integration.

When I tested, the user info came thru the Zap trigger.
