How to add a tag on a specific event

[Steve_Madar1]

We need an automation to tag a customer that is returning their purchase with 14 days.

We want to add the tag “to refund” upon these conditions;
They cancelled the order within 14 days of “activation date”

We have the following fields

• “delivered date”
• “cancellation date”

how do i make an automation to calculate the amount of days between those two fields and if the value is 1 through 14, add a tag to “line features”?

thanks for your help

You can do this without an automation using a simple formula field.

IF(
  AND(
    {activation date},
    {cancellation date},
    DATETIME_DIFF({cancellation date}, {activation date}, 'days') < 15
  ),
  'to refund',
  '-'
)

If you do want to use an automation, set your trigger to be “when Formula contains ‘to refund’”

no such trigger option.
