Hi @kanyewest7,
@Megan_Lask happened to ask the same question over here (same day too!) 🙂
To answer, you can construct an interface URL using a formula field to combine the part before the "rec..." at the end with RECORD_ID() in the same formula. The formula would look something like:
"https://airtable.com/appP5hH3nWTbTk2Iv/pag4lRoOvssMC0fRx?kgkbw=" & RECORD_ID()
with your interface's URL (minus the last "rec" part) between the quotes instead.
Then you are free to use this field in an automation or paste in Slack.
Hope that helps!
