I have a related issue I'd like to solve.
I would like to trigger a webhook which will initiate a phone call based on a specific datetime token.
The date token wait step today only seems to work with date tokens, not datetime tokens.
Were you able to get this to work Lysette?
I don't recall being able to select a date/time token when setting the wait step duration. While not ideal, what if you had 2 fields? 1 Date field and 1 Date/Time field.
Use the date field for the wait step and the date/time field for the webhook.
hope it helps!
