Hi @josem7,

Welcome to the Community. 

You can try create a date triggered flow and have it trigger 1 day before the date of the event following our Guide to Creating a Date Property-Triggered Flow.

Or, our date trigger works on the profile level rather than the metric level, this means within your API Call Payload you will need to make use of the Profile Properties section in https://developers.klaviyo.com/en/reference/track-post e.g:
 

{
  "token": "PUBLIC_KEY",
  "event": "RegisterTest",
  "customer_properties": {
    "$email": "abraham.lincoln@klaviyo.com",
    "DateProperty":"1409592848"
  },
  "properties": {
    "title": "TestPage",
    "URL": "www.TestURL.com"
  }
}

You would then link the date triggered flow to the DateProperty property and get it to trigger 1 day before that date takes place
 
I hope this helps,

Alex

Thanks Alex I will give it a try!

Wouldn’t it have the problem I mentioned of overwriting the property and hence the reminder? If it would overwrite it, then you should consider creating a flow that works also at the metric level I think it could have some useful applications

Thanks for the help

Hi @josem7,

Yes the profile property would overwrite but other Community members have gotten around this by setting up their signup forms or whatever the input may be so that this cannot happen and multiple inputs are not recorded.

@josem7 Were you ever able to accomplish this? We are having the same issue - wanting to send reminders to people that may have booked multiple tours. I’m hitting a wall.
